CIA transnational health and economic activities

This article deals with activities of the U.S. Central Intelligence Agency related to human survival issues, emphasizing disease and basic needs such as water and agriculture.


CIA activities in this area include the preparation of National Intelligence Estimates. They examine the most lethal diseases globally and by region; develops alternative scenarios about their future course; examines national and international capacities to deal with them; and assesses their national and global social, economic, political, and security impact. Next, they assess the infectious disease threat from international sources to the United States; to US military personnel overseas; and to regions in which the United States has or may develop significant equities.citation

Intelligence key judgments on the global infectious disease threat

The IC determined that new and reemerging infectious diseases will pose a rising global health threat and will complicate US and global security over the next 20 years. These diseases will endanger US citizens at home and abroad, threaten US armed forces deployed overseas, and exacerbate social and political instability in key countries and regions in which the United States has significant interestsNIE99-17D] .

Infectious diseases are a leading cause of death, accounting for a quarter to a third of the estimated 54 million deaths worldwide in 1998. The spread of infectious diseases results as much from changes in human behavior--including lifestyles and land use patterns, increased trade and travel, and inappropriate use of antibiotic drugs--as from mutations in pathogens. HIV prevalence will increase in five hard-hit countries, contributing to more instability:

:*Twenty well-known diseases--including tuberculosis(TB), malaria, and cholera--have reemerged or spread geographically since 1973, often in more virulent and drug-resistant forms.:*At least 30 previously unknown disease agents have been identified since 1973, including human immunodeficiency virus (HIV), Ebola, hepatitis C, and Nipah virus, for which no cures are available.:*Of the seven biggest killers worldwide, TB, malaria, hepatitis, and, in particular, HIV/AIDS continue to surge, with HIV/AIDS and TB likely to account for the overwhelming majority of deaths from infectious diseases in developing countries by 2020.:*Acute lower respiratory infections--including pneumonia and influenza--as well as diarrheal diseases and measles, appear to have peaked at high incidence levels. There is, however, always the possibility of an influenza pandemicsuch as "Spanish flu" of 1918-1920,cite book

] which actually appears to have originated in the US. By whatever name, that virus, of serotype H1N1 (i.e., different than the H5N1 "bird flu", killed between 40 and 50 million people. Its genome has been sequenced, there is a much better understanding of why it was so lethal, and there are some meaningful treatments. Those treatments, however, require, at the least, a robust pharmaceutical industry with appropriately fast drug distribution, and, at the higher levels of care, respiratory intensive care. Not even the most developed nations have adequate ICUs to handle a major epidemic; SARS was a warning in a city with the excellent medical facilities of Torontocitation

Regional trends

Developing and former communist countries will continue to experience the greatest impact from infectious diseases--because of malnutrition, poor sanitation, poor water quality, and inadequate health care--but developed countries also will be affected. NIE99-17D]

Impact within the United States

Although the infectious disease threat in the United States remains relatively modest as compared to that of noninfectious diseases, the trend is up. Annual infectious disease-related death rates in the United States have nearly doubled to some 170,000 annually after reaching an historic low in 1980.citation

] Many infectious diseases--most recently, the West Nile virus--originate outside US borders and are introduced by international travelers, immigrants, returning US military personnel, or imported animals and foodstuffs. In the opinion of the US Institute of Medicine, the next major infectious disease threat to the United States may be, like HIV, a previously unrecognized pathogen. Barring that, the most dangerous known infectious diseases likely to threaten the United States over the next two decades will be HIV/AIDS, hepatitis C,tuberculosis, and new, more lethal variants of influenza. Hospital-acquired infectionscitation

] and foodborne illnesses also will pose a threatNIE99-17D] .:*Although multidrug therapies have cut HIV/AIDS deaths by two-thirds to 17,000 annually since 1995, emerging microbial resistance to such drugs and continued new infections will sustain the threat.:*Some 4 million Americans are chronic carriers of the hepatitis C virus, a significant cause of liver cancer and cirrhosis. The US death toll from the virus may surpass that of HIV/AIDS in the next five years.:*TB, exacerbated by multidrug resistant strains and HIV/AIDS co-infection, has made a comeback. Although a massive and costly control effort is achieving considerable success, the threat will be sustained by the spread of HIV and the growing number of new, particularly illegal, immigrants infected with TB.:*Influenza now kills some 30,000 Americans annually, and epidemiologists generally agree that it is not a question of whether, but when, the next killer pandemic will occur.:*Highly virulent and increasingly antimicrobial resistant pathogens, such as "Staphylococcus aureus", are major sources of hospital-acquired infections that kill some 14,000 patients annually.:*The doubling of US food imports over the last five years is one of the factors contributing to tens of millions of foodborne illnesses and 9,000 deaths that occur annually, and the trend is up.

ub-Saharan Africa

65% of all deaths in Sub-Saharan Africa come from infectious diseases. Rudimentary health care delivery and response systems, the unavailability or misuse of drugs, the lack of funds, and the multiplicity of conflicts are exacerbating the crisis. According to the AFMIC typology, with the exception of southern Africa, most of Sub-Saharan Africa falls in the lowest category. Investment in health care in the region is minimal, less than 40 percent of the people in countries such as Nigeria and the Democratic Republic of the Congo (DRC) have access to basic medical care, and even in relatively well off South Africa, only 50-70%t have such access, with black populations at the low end of the spectrum. It will remain the most vulnerable region. The death rates for many diseases, including HIV/AIDS and malaria, exceed those in all other regions. Sub-Saharan Africa's health care capacity--the poorest in the world--will continue to lag.citation

chapter = Subsaharan Africa

Four-fifths of all HIV-related deaths and 70 percent of new infections worldwide in 1998 occurred in the region. Although only a tenth of the world's population lives in the region, 11.5 million of 13.9 million cumulative AIDS deaths have occurred there. Eastern and southern African countries, including South Africa, are the worst affected, with 10-26% of adults infected with the disease.citation

Sub-Saharan Africa has an estimated 90 percent of the global malaria burden. Cholera, dysentery, and other diarrheal diseases also are major killers in the region, particularly among children, refugees, and internally displaced populations. Forty percent of all childhood deaths from diarrheal diseases occur in Sub-Saharan Africa. The region also has a high rate of hepatitis B and C infections and is the only region with a perennial meningococcal meningitis problem in a "meningitis belt" stretching from west to east.NIE99-17D] citation

] Sub-Saharan Africa also suffers from yellow fever, while trypanosomiasis or "sleeping sickness" is making a comeback in the DROC and Sudan, and the Marburg virus also appeared in DRC for the first time in 1998. Ebola hemorrhagic fever strikes sporadically in countries such as the DRC, Gabon, Cote d'Ivoire, and Sudan.

Ethiopia's second wave

Ethiopia is estimated to have the highest adult prevalence rate, between 10-18%—is the highest among the five countries. This reflects two social effects::*Like Nigeria, the disease has moved into the general population:*Unlike the other countries, the effects of war have a significant effect on spread::*Another surge of infections may be underway from the 150,000 demobilized soldiers over the last two years as the conflict with Eritrea has wound down. More troops will be sent home as the border dispute is settled.::*As soldiers demobilize, prostitutes—who have even higher rates of infection—disperse around the country as well.The figure to the right shows prevalence at prenatal clinics, which appears to be the best single indicator. Expert estimates the actual number of HIV patients may be between 3 and 5 million. Adult prevalence is much higher in cities (13-20%) than in rural areas (5%). Heterosexual transmission is the primary mode of spread, and people with multiple partners—especially those with sexually transmitted diseases (STDs) and prostitutes—have significantly higher infection rates.

Unlike conditions in other next-wave countries, war has significantly contributed to the spread of the disease in Ethiopia. Many soldiers contracted HIV/AIDS during the civil war in the 1980s by having contact with multiple sex partners. When the war ended in 1991, thousands of infected soldiers and prostitutes returned home, spreading HIV/AIDS in their villages and towns. Ethiopians, due to result of drought, malnutrition, limited healthcare, and other infectious diseases, have generally poor health. In the HIV-seropositive group, this has caused HIV to progress rapidly to AIDS. Looking ahead, we expect 7 to 10 million Ethiopians probably will be infected by 2010 because of the high current rate of adult prevalence, widespread poverty, low educational levels, and the government’s limited capacity to respond more actively.

Nigeria's second wave

Heterosexual transmission of the HIV virus is the primary mode of spread in Nigeria, and infections appear to be as numerous in rural areas as in the cities. In other words, HIV is in the general population. The reported rate of infection apparently varies significantly by region, with the lowest reported rate found generally in the predominantly Muslim northern parts of the country. Infections are most numerous among men ages 20 through 24, but some experts caution that infection rates are rising quickly in young women. citation

] Given the already advanced state of the disease and the government’s limited capacity to respond, the Intelligence Community expects HIV/AIDS to infect as many as 10 to 15 million people by 2010. Nigerian prevalence may be 18 to 26 percent of adults—close to the current rates in some of the hardest hit countries in southern Africa. This graphic is of a second-wave country; Southern Africa is already badly affected by the first wave.

Asia and the Pacific

Multidrug resistant TB, malaria, and cholera are rampant in this area. The spread of HIV/AIDS, with its immunosuppression, will lead to a dramatic increase in infectious disease deaths. By 2010, the region could surpass Africa in the number of HIV infections.citation

chapter = Asia and the Pacific

Although the more developed countries of Asia and the Pacific, such as Japan, South Korea, Australia, and New Zealand, have strong records in combating infectious diseases, infectious disease prevalence in South and Southeast Asia is almost as high as in Sub-Saharan Africa. The health care delivery system of the Asia and Pacific region--the majority of which is privately financed--is particularly vulnerable to economic downturns even though this is offset to some degree by much of the region's reliance on traditional medicine from local practitioners. In South and Southeast Asia, reemergent diseases such as TB, malaria, cholera, and dengue fever are rampant, while HIV/AIDS, after a late start, is growing faster than in any other region.

TB caused 1 million deaths in the Asia and Pacific region in 1998, more than any other single disease, with India and China accounting for two-thirds of the totalNIE99-17D] . Several million new cases occur annually--most in India, China and Indonesia--representing as much as 40 percent of the global TB burden. HIV/AIDS is increasing dramatically, especially in India, which leads the world in absolute numbers of HIV/AIDS infections, estimated at 3-5 million. China is better off than most of the countries to its south, but it too has a growing AIDS problem, with HIV infections variously estimated at 100,000 to 4000,000. and spreading rapidly. Regionwide, the number of people infected with HIV could overtake Sub-Saharan Africa in absolute numbers before 2010.

Former Soviet Union (FSU) and Eastern Europe

These areas will see a substantial increase in infectious disease incidence and deaths. In the FSU especially, the steep deterioration in health care and other services owing to economic decline has led to a sharp rise in diphtheria, dysentery, cholera, and hepatitis B and C. TB has reached epidemic proportions throughout the FSU, while the HIV-infected population in Russia alone could exceed 1 million by the end of 2000 and double yet again by 2002.citation

chapter = Former Soviet Union (FSU) and Eastern Europe
] The sharp decline in health care infrastructure in Russia and elsewhere in the former Soviet Union (FSU) and, to a lesser extent, in Eastern Europe--owing to economic difficulties--are causing a dramatic rise in infectious disease incidence. Death rates attributed to infectious diseases in the FSU increased 50% from 1990 to 1996, with TB accounting for a substantial number of such deaths. Access to health care ranges from 50-70% in most European FSU states, including Russia and Ukraine, and from 40-50% in FSU states located in Central Asia. WHO estimates are consistent, that only 50-80% of FSU citizens had regular access to essential drugs in 1997, as compared to more than 95% a decade earlier as health care budgets and government-provided health services were slashed. Health care access is better in Eastern Europe, particularly in more developed states such as Poland, the Czech Republic, and Hungary, where it ranges from 70-90%, while only 50-70% have access in countries such as Bulgaria and Romania. More than 95 percent of the population throughout the East European region had such access in 1987, according to WHO.

Crowded living conditions are among the causes fueling a TB epidemic in the FSU, especially among prison populations--while surging intravenous drug abuse (IVDA) and rampant prostitution are substantially responsible for a marked increase in HIV/AIDS incidence. There were 111,000 new TB infections and 25,000 deaths in Russia alone in 1996, a growing number of them multidrug resistant. The number of new infections for the entire FSU in 1996 was 188,000, while East European cases totaled 54,000.

Diphtheria reached epidemic proportions in the FSU in the first half of the decade, owing to lapses in vaccination. Cholera and dysentery outbreaks are occurring with increasing frequency in Russian cities, such as St. Petersburg and Moscow, and elsewhere in the FSU, such as in T'bilisi, owing to deteriorating water treatment and sewerage systems. Hepatitis B and C, spread primarily by IVDA and blood transfusions, are on the rise, especially in the non-European part of the FSU. Polio also has reappeared owing to interruptions in vaccination, with 140 new cases in Russia in 1995. .

Russian HIV 2nd wave

Each country in the second wave have different social factors causing increased spread. HIV has not yet made a move into the general populations of some countries, such as Russia. The single social factor (80-90% of new cases) for Russian spread is IVDA, coming from prostitutes and prison inmates—many of whom are IVDAs—are contributing to the spread of the disease. Drug use is so widespread that many users are integrated into society with jobs and families, suggesting the disease is moving into the mainstream. An estimated 20-25% of IVDA in prison, where there is easy access to drugs, are seropositive .

HIV/AIDS also is increasing in the Russian military services. Up to 33% of prospective conscripts are deemed unfit for service owing to the effects of prior drug use (chronic hepatitis or HIV infection). Enlisted men in the ground troops have the largest number of infections, while strategic military forces and airborne troops have the lowest.

Latin America

There is distinct progress in infectious disease control in this region, including the eradication of polio, but uneven economic development has contributed to widespread resurgence of cholera, malaria, TB, and dengue. These diseases will continue to take a heavy toll in tropical and poorer countries.citation

chapter = Latin America

Latin American countries are making considerable progress in infectious disease control, including the eradication of polio and major reductions in the incidence and death rates of measles, neonatal tetanus, some diarrheal diseases, and acute respiratory infections. Nonetheless, infectious diseases are still a major cause of illness and death in the region, and the risk of new and reemerging diseases remains substantial.citation

] Widening income disparities, periodic economic shocks, and rampant urbanization have disrupted disease control efforts and contributed to widespread reemergence of cholera, malaria, TB, and dengue, especially in the poorer Central American and Caribbean countries and in the Amazon basin of South America. According to the AFMIC typology, Latin America's health care capacity is substantially more advanced than that of Sub-Saharan Africa and somewhat better than mainland Asia's, with 70-90% of populations having access to basic health care in Chile, Costa Rica, and Cuba on the upper end of the scale. Less than 50 percent have such access in Haiti, most of Central America, and the Amazon basin countries, including the rural populations in Brazil.

Cholera reemerged with a vengeance in the region in 1991 for the first time in a century with 400,000 new cases, and while dropping to 100,000 cases in 1997, it still comprises two-thirds of the global cholera burden. TB is a growing problem regionwide, especially in Brazil, Peru, Argentina, and the Dominican Republic where drug-resistant cases also are on the rise. Haiti does not provide data but probably also has a high infection rate. HIV/AIDS also is spreading rapidly, placing Latin America third behind Sub-Saharan Africa and Asia in HIV prevalence. Prevalence is high in Brazil and especially in the Caribbean countries (except Cuba), where 2 percent of the population is infected. Malaria is prevalent in the Amazon basin. Dengue reemerged in the region in 1976, presenting both as the usual form and the more lethal dengue hemorrhagic fever (DHF). Hepatitis B and C prevalence is greatest in the Amazon basin, Bolivia, and Central America, while DHF is particularly prevalent in Brazil, Colombia, and Venezuela. Yellow fever has made a comeback over the last decade throughout the Amazon basin, and there have been several recent outbreaks of gastrointestinal disease attributed to "E. coli" infection in Chile, Argentina, Bolivia and Perucitation

The Middle East and North Africa region

has substantial TB and hepatitis B and C prevalence, but conservative social mores, climatic factors, and the high level of health spending in the oil-producing states tend to limit some globally prevalent diseases, such as HIV/AIDS and malaria. The region has the lowest HIV infection rate among all regions, although this is probably due in part to above-average underreporting because of the stigma associated with the disease in Muslim societies.citation

chapter = The Middle East and North Africa region

The region's conservative social mores, climatic factors, and high levels of health spending in oil-producing states tend to limit some globally prevalent diseases, such as HIV/AIDS and malaria, but others, such as TB and hepatitis B and C, are more prevalent. The region's advantages are partially offset by the impact of war-related uprooting of populations, overcrowded cities with poor refrigeration and sanitation systems, and a dearth of water, especially clean drinking water. Health care capacity varies considerably within the region, according to the AFMIC typology. Israel and the Arabian Peninsula states minus Yemen are in far better shape than Iraq, Iran, Syria, and most of North Africa. Ninety to 100 percent of the Israeli population and 70 to 90 percent of the Saudi population have good access to health care. Elsewhere, access ranges from less than 40 percent in Yemen to 50 to 70 percent in the smaller Gulf states, Jordan and Tunisia, while most North African states fall into the 40- to 50-percent category.

Western Europe

Threats from several infectious diseases, include both thjose transmitted by humans, such as HIV/AIDS, TB, and hepatitis B and C, as well as from several economically costly zoonotic diseases (that is, those transmitted from animals to humans). The region's large volume of travel, trade, and immigration increases the risks of importing diseases from other regions, but its highly developed health care system will limit their impact.citation
title = National Intelligence Estimate 99-17D: The Global Infectious Disease Threat and Its Implications for the United States
date = January 2000
url =
chapter = Western Europe

Its status as a hub of international travel, commerce, and immigration, moreover, dramatically increases the risks of importing new diseases from other regions. Tens of millions of West Europeans travel to developing countries annually, increasing the prospects for the importation of dangerous diseases, as demonstrated by the importation of typhoid in 1999. Some 88 percent of regional population growth in the first half of the decade was due to immigration; legal immigrants now comprise about 6 percent of the population, and illegal newcomers number an estimated 6 million. Nonetheless, the region's highly developed health care infrastructure and delivery system tend to limit the incidence and especially the death rates of most infectious diseases, though not the economic costs. Access to high-quality care is available throughout most of the region, although governments are beginning to limit some heretofore generous health benefits, and a growing antivaccination movement in parts of Western Europe, such as Germany, is causing a rise in measles and other vaccine-preventable diseases. The AFMIC typology gives somewhat higher marks to northern over some southern European countries, but the region as a whole is ranked in the highest category, along with North America.

TB, especially its multidrug resistant strains, is on the upswing,citation

] as is co-infection with HIV, particularly in the larger countries, with some 50,000 TB cases reported in 1996. Hepatitis C prevalence is growing, especially in southern Europe. Western Europe also continues to suffer from several zoonotic diseases, among which is the deadly new variant Creutzfeldt-Jakob disease (nvCJD), linked to the bovine spongiform encephalopathy or "mad cow disease" outbreak in the United Kingdom in 1995 that has since ebbed following implementation of strict control measures. Other recent disease concerns include meningococcal meningitis outbreaks in the Benelux countries and leishmaniasis-HIV co-infection, especially in southern Europe.

Response capacity

Development of an effective global surveillance and response system probably is at least a decade or more away, owing to inadequate coordination and funding at the international level and lack of capacity, funds, and commitment in many developing and former communist states. Although overall global health care capacity has improved substantially in recent decades, the gap between rich and poorer countries in the availability and quality of health care.

In most poorer countries, health care--ranging from basic pharmaceuticals and postnatal care to costly multidrug therapies--remains very limited. Market forces drive private pharmaceutical companies, and many developed country government research programs, to focus on drugs needed in their environment, not necessarily those of the poorer countries. This is generating a growing controversy between rich and poorer nations over such issues as intellectual property rights, as some developing countries make their own copies, not always with permission, of drugs under patent protection.citation

A global composite measure of health care infrastructure devised by DIA's Armed Forces Medical Intelligence Center (AFMIC) assesses factors such as the priority attributed to health care, health expenditures, the quality of health care delivery and access to drugs, and the extent of surveillance and response systems.

A major obstacle to effective global surveillance and control of infectious diseases will continue to be the quality of national health statistical reporting by many developing countries and lack of followthrough to properly direct aid and to follow recommended health care practices. Those areas of the world most susceptible to infectious disease problems are least able to develop and maintain the sophisticated and costly communications equipment needed for effective disease surveillance and reporting. In addition to the barriers dictated by low levels of development, revealing a disease outbreakmay harm national prestige, commerce, and tourism. For example, nearly every country initially denied or minimized the extent of the HIV/AIDS virus within its borders, and even today, some countries known to have significant rates of HIV infection refuse to cooperate with WHO. Only a few, such as Uganda, Senegal, and Thailand, have launched major preventative efforts, while many WHO members do not even endorse AIDS education in schools. Similarly, some countries deny the existence of cholera within their borders.

Aid programs to prevent and treat infectious diseases in developing countries depend largely on indigenous health workers for their success and cannot be fielded effectively in their absence. Training indigenous workers appears more effective than educating the general public of these countries.

International organizations such as WHO and the World Bank, institutions in several developed countries such as the US CDC, and Nongovernmental Organizations (NGOs) will continue to play an important role in strengthening both international and national surveillance and response systems for infectious diseases. Development of an integrated global surveillance and response system probably is at least a decade or more away. This owes to the magnitude of the challenge; inadequate coordination at the international level; and lack of funds, capacity, and, in some cases, cooperation and commitment at the national level. Some countries hide or understate their infectious disease problems for reasons of prestige and fear of economic losses. Total international health-related aid to low- and middle-income countries--some $2-3 billion annually--remains a fraction of the $250 billion health bill of these countries.

WHO has the broadest health mandate under the UN system, including setting priorities, coordinating global health surveillance, and emergency assistance in the event of disease outbreaks. Health experts give WHO credit for major successes, such as the eradication of smallpox, near eradication of polio, and substantial progress in controlling childhood diseases, and in expanding primary health care in developing countries. WHO defenders blame continued member state parsimony that has kept WHO's regular biennial budget to roughly $850 million for several years and forced it to rely more on voluntary contributions that often come with strings attached as the cause of its shortcomings. This situation led to lack of focus at the top level as well as overly optimistic forecasts.

The 1998 election of Gro Harlem Brundtland as Secretary General, along with a series of reforms, including expansion of the Emerging and other Communicable Diseases Surveillance and Control (EMC) Division, has placed WHO in a better position to revitalize itself. Internal oversight and transparency have been expanded, programs and budgets are undergoing closer scrutiny, and management accountability is looming larger. Bruntland has moved quickly to revitalize top management, mostly from outside the organization, including from the private sector. She also strengthened country offices and to made the regional offices more responsive to central direction. WHO is increasing its focus on the fight against resurgent malaria, while a better-funded EMC is expanding efforts to establish a global surveillance and response system in cooperation with UNAIDS, UNICEF, and national entities such as the US CDC, the US DoD, and France's Pasteur Institute. Margaret Chan, the current Director-General, is still being assessed; there were questions about her performance as chief of public health for Hong Kong.

WHO competes for resources with other UN agencies that are involved in health care. The United Nations Children's Fund (UNICEF) focuses on children's health. The United Nations AIDS Program (UNAIDS) focuses on improving the response capacity toward HIV/AIDS at the country, regional, and global levels in cooperation with other UN agencies. Other UN agencies involved in health care issues include the UN Development Program (UNDP); the UN Family Planning Agency (UNFPA); the UN High Commissioner for Refugees (UNHCR); the UN Educational, Scientific and Cultural Organization (UNESCO); the International Labor Organization (ILO); the Food and Agricultural Organization (FAO); and the World Food Program (WFP).

Alternative scenarios

The 1999 estimatecitation

chapter = Alternative Scenerios
] looked at three plausible scenarios for the course of the infectious disease threat over the next 20 years::#Steady progress to a "health transition" in which such noninfectious diseases as heart disease and cancer would replace infectious diseases as the overarching global health challenge. The intelligence community states this is unlikely, givem inadequate emphasis to persistent demographic and socioeconomic challenges in the developing countries, to increasing microbial resistance to existing antibiotics, and because related models have already underestimated the force of major killers such as HIV/AIDS, TB, and malaria.:#"Progress stymied" is a more pessimistic--and more plausible--scenario projects little or no progress in countering infectious diseases over the duration of this Estimate. Under this scenario, HIV/AIDS reaches catastrophic proportions as the virus spreads throughout the vast populations of India, China, the former Soviet Union, and Latin America, while multidrug treatments encounter microbial resistance and remain prohibitively expensive for developing countries. Multidrug resistant strains of TB, malaria, and other infectious diseases appear at a faster pace than new drugs and vaccines, wreaking havoc on world health. Although more likely than the "steady progress" scenario, the IC judges this unlikely, because it is overoptimistic about the prospect of development, collaboration, and medical advances to constrain the spread of at least some widespread infectious diseases.:#"Deterioration, Then Limited Improvement" is judged most likely by the IC. The infectious disease threat--particularly from HIV/AIDS--worsens during the first half of our time frame, but decreases fitfully after that, owing to better prevention and control efforts, new drugs and vaccines, and socioeconomic improvements. In the next decade, under this scenario, negative demographic and social conditions in developing countries, such as continued urbanization and poor health care capacity, remain conducive to the spread of infectious diseases; persistent poverty sustains the least developed countries as reservoirs of infection; and microbial resistance continues to increase faster than the pace of new drug and vaccine development.cite book

] More positive demographic changes such as reduced fertility and aging populations; gradual socioeconomic improvement in most countries; medical advances; expanded international surveillance and response systems; and improvements in national health care capacities take hold in all but the least developed countries. Barring the appearance of a deadly and highly infectious new disease, a catastrophic upward lurch by HIV/AIDS, or the release of a highly contagious biological agent capable of rapid and widescale secondary spread, these developments produce at least limited gains against the overall infectious disease threat. The remaining virulent diseases, led by HIV/AIDS and TB, continue to take a significant toll.

Economic, social, and political impact

The persistent infectious disease burden is likely to aggravate and, in some cases, may even provoke economic decay, social fragmentation, and political destabilization in the hardest hit countries in the developing and former communist worlds, especially in the worst case scenario outlined above:citation

chapter = Economic, Social, and Political Impact

:*The economic costs of infectious diseases--especially HIV/AIDS and malaria--are already significant, and their increasingly heavy toll on productivity, profitability, and foreign investment will be reflected in growing GDP losses, as well, that could reduce GDP by as much as 20 percent or more by 2010 in some Sub-Saharan African countries, according to recent studies.

:*Some of the hardest hit countries in Sub-Saharan Africa--and possibly later in South and Southeast Asia--will face a demographic upheaval as HIV/AIDS and associated diseases reduce human life expectancy by as much as 30 years and kill as many as a quarter of their populations over a decade or less, producing a huge orphan cohort. Nearly 42 million children in 27 countries will lose one or both parents to AIDS by 2010; 19 of the hardest hit countries will be in Sub-Saharan Africa.

The relationship between disease and political instability is indirect but real. A wide-ranging study on the causes of state instability suggests that infant mortality--a good indicator of the overall quality of life--correlates strongly with political instability, particularly in countries that already have achieved a measure of democracy. The severe social and economic impact of infectious diseases is likely to intensify the struggle for political power to control scarce state resources.

As a major hub of global travel, immigration, and commerce with wide-ranging interests and a large civilian and military presence overseas, the United States and its equities abroad will remain at risk from infectious diseases.

:*Emerging and reemerging infectious diseases, many of which are likely to continue to originate overseas, will continue to kill at least 170,000 Americans annually. Many more could perish in an epidemic of influenza or yet-unknown disease or if there is a substantial decline in the effectiveness of available HIV/AIDS drugs.:*Infectious diseases are likely to continue to account for more military hospital admissions than battlefield injuries. US military personnel deployed at NATO and US bases overseas, will be at low-to-moderate risk. At highest risk will be US military forces deployed in support of humanitarian and peacekeeping operations in developing countries.:*The infectious disease burden will weaken the military capabilities of some countries--as well as international peacekeeping efforts--as their armies and recruitment pools experience HIV infection rates ranging from 10 to 60 percent. The cost will be highest among officers and the more modernized militaries in Sub-Saharan Africa and increasingly among FSU states and possibly some rogue states.:*Infectious diseases are likely to slow socioeconomic development in the hardest-hit developing and former communist countries and regions. This will challenge democratic development and transitions and possibly contribute to humanitarian emergencies and civil conflicts.:*Infectious disease-related embargoes and restrictions on travel and immigration will cause frictions among and between developed and developing countries

Patterns of infectious diseases

Broad advances in controlling or eradicating a growing number of infectious diseases--such as tuberculosis (TB), malaria, and smallpox--in the decades after WWII fueled hopes that the global infectious disease threat would be increasingly manageable. This optimism, however, led to complacency and overlooked the role of such factors as expanded trade and travel and growing microbial resistance to existing antibiotics in the spread of infectious diseases. According to the 1999 NIE, citation

chapter = Patterns of Infectious Disease

:*Infectious diseases remain a leading cause of death. Of the estimated 54 million deaths worldwide in 1998, about one-fourth to one-third were due to infectious diseases, most of them in developing countries and among children globally.:*Infectious diseases accounted for 41 percent of the global disease burden measured in terms of Disability-Adjusted Life Years (DALYS) that gauge the impact of both deaths and disabilities, as compared to 43 percent for noninfectious diseases and 16 percent for injuries.:*Although there has been continuing progress in controlling some vaccine-preventable childhood diseases such as polio, neonatal tetanus, and measles, a White House-appointed interagency working group identified at least 29 previously unknown diseases that have appeared globally since 1973, many of them incurable, including HIV/AIDS, Ebola hemorrhagic fever, and hepatitis C. Most recently, Nipah encephalitis was identified. Twenty well-known diseases such as malaria, TB, cholera, and dengue have rebounded after a period of decline or spread to new regions, often in deadlier forms.:*These trends are reflected in the United States as well, where annual infectious disease deaths have nearly doubled to some 170,000 since 1980 after reaching historic lows that year, while new and existing pathogens, such as HIV and West Nile virus, respectively, continue to enter US borders.


Detection and control of emerging infectious diseases in conflict situations are major challenges due to multiple risk factors known to enhance emergence and transmission of infectious diseases. These include inadequate surveillance and response systems, destroyed infrastructure, collapsed health systems and disruption of disease control programs, and infection control practices even more inadequate than those in resource-poor settings, as well as ongoing insecurity and poor coordination among humanitarian agencies. citation

The probability of a bioterrorist attack against US civilian and military personnel overseas or in the United States also is likely to grow as more states and groups develop a biological warfare capability. Although there is no evidence that the recent West Nile virus outbreak in New York City was caused by foreign state or nonstate actors, the scare and several earlier instances of suspected bioterrorism showed the confusion and fear they can sow regardless of whether or not they are validated.citation

One of the challenges of detecting bioterrorism is that while automated aerosol detection equipment exists, it can cover only limited physical areas, such as high-value targets or troop concentration. In a civilian population, the first warning of covert terrorism is apt to come from clinicians that can compare many cases. An emergency room is one obvious place for comparison, but the availability of electronic health records, from which data from many office encounters can be extracted, with due regard for privacy, and searched for patterns.

Multidrug resistance and coinfection

Another reason for the increased danger of infectious diseases is antibiotic resistance, especially Multidrug resistance. By themselves, bacteria can transfer the genes for resistance to a specific antibiotics. Improper medical use, where antibiotics are not needed for the actual problem but expose other bacteria to be selected out as resistant, or where patients do not take the full prescribed course, are significant sources of new forms. Use as an agricultural growth stimulant is generating resistant forms. While researchers continue to develop new classes of antibiotics, the rate of development is slower than the emergence of resistant forms.IOM2003]

War and other factors are spreading resistant forms. In the US, "Acinetobacter" strains were previously seen only in immunosuppressed patients, but "Acinetobacter baumanii" has been a common, and drug-resistant, infection in military patients from Iraq and Afghanistan.citation

pread through rapid transportation

The increase in international air travel, trade, and tourism will dramatically increase the prospects that infectious disease pathogens such as influenza--and vectors such as mosquitoes and rodents--will spread quickly around the globe, often in less time than the incubation period of most diseases. Earlier in the decade, for example, a multidrug resistant strain of "Streptococcus pneumoniae" originating in Spain spread throughout the world in a matter of weeks, according to the director of WHO's infectious disease division. The cross-border movement of some 2 million people each day, including 1 million between developed and developing countries each week, and surging global trade ensure that travel and commerce will remain key factors in the spread of infectious diseases.<

Technology, medicine, and industry

Although technological breakthroughs will greatly facilitate the detection, diagnosis, and control of certain infectious and noninfectious illnesses, they also will introduce new dangers, especially in the developed world where they are used extensively. Invasive medical procedures will result in a variety of hospital-acquired infections, such as "Staphylococcus aureus". The globalization of the food supply means that nonhygienic food production, preparation, and handling practices in originating countries can introduce pathogens endangering foreign as well as local populations. Disease outbreaks due to "Cyclospora spp, Escherichia coli," and "Salmonella spp." in several countries, along with the emergence, primarily in Britain, of Bovine Spongiform Encephalopathy, or "mad cow" disease, and the related new variant Creutzfeldt-Jakob disease (nvCJD) affecting humans, result from such food practices.

Antibiotics as an agricultural growth stimulant

Many farmers have found they have fewer fatalities and greater meat yield if antibiotics are given to feed animals who show no evidence of disease. citation

] Antibiotic use in food animal production has been associated with the emergence of antibiotic-resistant strains of bacteria including "Salmonella" spp., "Campylobacter" spp., "Escherichia coli", and "Enterococcus" spp. Evidence from some US and European studies suggest that these resistant bacteria cause infections in humans that do not respond to commonly prescribed antibiotics.

In response to these practices and attendant problems, several organizations (e.g. The American Society for Microbiology (ASM), American Public Health Association (APHA)cite web

title = HCWH Policy Statement on Antibiotics in Food
] and the American Medical Association (AMA)) have called for restrictions on antibiotic use in food animal production and an end to all non-therapeutic uses.

Inappropriate use of antimicrobial drugs in humans

There is misuse of antimicrobial drugs, antimicrobial being defined as a superset of antibiotics that include disinfectants in both developed and less-developed countries, although the inappropriate treatment varies with the medical standards of the country.

Developed countries: overuse of antibiotics

One study on respiratory tract infections found "physicians were more likely to prescribe antibiotics to patients who they believed expected them, although they correctly identified only about 1 in 4 of those patients".cite journal |author=Ong S, Nakase J, Moran GJ, Karras DJ, Kuehnert MJ, Talan DA |title=Antibiotic use for emergency department patients with upper respiratory infections: prescribing practices, patient expectations, and patient satisfaction |journal=Annals of emergency medicine |volume=50 |issue=3 |pages=213–20 |year=2007 |pmid=17467120 |doi=10.1016/j.annemergmed.2007.03.026] Multifactorial interventions aimed at both physicians and patients can reduce inappropriate prescribing of antibiotics. cite journal |author=Metlay JP, Camargo CA, MacKenzie T, "et al" |title=Cluster-randomized trial to improve antibiotic use for adults with acute respiratory infections treated in emergency departments |journal=Annals of emergency medicine |volume=50 |issue=3 |pages=221–30 |year=2007 |pmid=17509729 |doi=10.1016/j.annemergmed.2007.03.022] Delaying antibiotics for 48 hours while observing for spontaneous resolution of respiratory tract infections may reduce antibiotic usage; however, this strategy may reduce patient satisfaction.cite journal |author=Spurling G, Del Mar C, Dooley L, Foxlee R |title=Delayed antibiotics for respiratory infections |journal=Cochrane database of systematic reviews (Online) |volume= |issue=3 |pages=CD004417 |year=2007 |pmid=17636757 |doi=10.1002/14651858.CD004417.pub3]

Economic development and land use

Changes in land and water use patterns will remain major factors in the spread of infectious diseases. The emergence of Lyme disease in the United States and Europe has been linked to reforestation and increases in the deer tick population, which acts as a vector, while conversion of grasslands to farming in Asia encourages the growth of rodent populations carrying hemorrhagic fever and other viral diseases. Human encroachment on tropical forests will bring populations into closer proximity with insects and animals carrying diseases such as leishmaniasis, malaria, and yellow fever, as well as heretofore unknown and potentially dangerous diseases, as was the case with HIV/AIDS. Close contact between humans and animals in the context of farming will increase the incidence of zoonotic diseases--those transmitted from animals to humans. Water management efforts, such as dambuilding, will encourage the spread of water-breeding vectors such as mosquitoes and snails that have contributed to outbreaks of Rift Valley fever and schistosomiasis in Africa.

Global animal trade

Globalization has had an impact on the worldwide animal trade. This worldwide movement of animals has increased the potential for the translocation of zoonotic diseases, which pose serious risks to human and animal health.

The magnitude of the global movement of animals is staggering. In terms of sheer numbers, 37,858,179 individually counted live amphibians, birds, mammals, and reptiles were legally imported to the United States from 163 countries in 2000–2004.

Animals are legally imported into the United States for many reasons. They are used for exhibitions at zoos; scientific education, research, and conservation programs; food and products; and in the case of companion animals, tourism and immigration. Increasingly, however, animals are being imported for a thriving commercial pet trade. In many cases the animals that are imported and traded are of species that are considered exotic (here defined as non-native species, animals not traditionally kept as pets, or both). This can be a risky business, as many shipments include a high volume of wild-caught versus captive raised. For most of these animals, there are no requirements for zoonotic disease screening either before or after arrival into the United States. There have been anecdotal reports of high rates of death among animals in these shipments.

Animals imported for commercial trade represent a substantial risk to human health. In 2003, monkeypox was introduced into the United States when a shipment of African rodents was distributed to various US exotic pet dealers, one of whom housed these animals with prairie dogs. The prairie dogs subsequently became ill and transmitted the infection to 47 humans, including prairie dog owners and veterinary staff caring for the ill animals. In addition to monkeypox, human tularemia and salmonellosis outbreaks have been traced back to contact with prairie dogs and hedgehogs.

Exotic pet ownership brings unanticipated risks to agribusiness, wildlife conservation, and the ecosystem. For example, giant African land snails released into farmlands have become agricultural pests. They reproduce rapidly, consume large amounts of vegetation, and are hosts for parasites such as "Angiostrongylus cantonensis". The illegal trade of exotic wildlife, with promises of considerable financial return in the underground markets, has disastrous implications for many endangered or threatened species.citation

Priority diseases

The seven infectious diseases that caused the highest number of deaths in 1998, according to WHO and DIA's Armed Forces Medical Intelligence Center (AFMIC), will remain threats well into the next century. HIV/AIDS, TB, malaria, and hepatitis B and C--are either spreading or becoming more drug-resistant, while lower respiratory infections, diarrheal diseases, and measles, appear to have at least temporarily peaked. citation

Human Immunodeficiency Virus

The National Intelligence Council has worked with a concept of "waves" of AIDS, with first wave in Subsaharan Africa, but the next wave, to be evident by 2010, will spread significantly into Asia and Russia.

Intelligence estimates of infection rates and their likely trajectories go beyond the official statistics by incorporating the assessments of academics and NGOs with field experience. The numbers cited in the estimages should be considered rough estimates with a relatively high margin of error. Infection surveillance of women attending prenatal clinics is considered the most reliable indicator of adult Human Immunodeficiency Virus (HIV) prevalence in the general population. But even these statistics can be affected by poor clinic attendance when fee for services or mandatory HIV testing is instituted.citation

HIV estimates in 1999

An IC 1999 paper, which focused on the spread of AIDS in the context of other growing infectious diseases, observed that following its identification in 1983, the spread of HIV intensified quickly. Despite progress in some regions, HIV/AIDS shows no signs of abating globally. According to WHO, some 33.4 million people were living with HIV by 1998, up from 10 million in 1990, and the number could approach 40 million by the end of 2000. Although infection and death rates have slowed considerably in developed countries owing to the growing use of preventive measures and costly new multidrug treatment therapies, the pandemic continues to spread in much of the developing world, where 95 percent of global infections and deaths have occurred. Sub-Saharan Africa currently has the biggest regional burden, but the disease is spreading quickly in India, Russia, China, and much of the rest of Asia. HIV/AIDS probably will cause more deaths than any other single infectious disease worldwide by 2020 and may account for up to one-half or more of infectious disease deaths in the developing world alone.

HIV estimates in 2003

HIV/AIDS problem through 2010 in five countries of strategic importance to the United States that have large populations at risk for HIV infection: Nigeria, Ethiopia, Russia, India, and China. The paper does not attempt to make aggregate projections about global trends.ICA2002-04D] The five countries were selected because they are::*Among the world’s most populous countries, together representing over 40 percent of the world population.:*In the early-to-mid-stages of an HIV/AIDS epidemic.:*Led by governments that have not yet given the issue the sustained high priority that has been key to stemming the tide of the disease in other countries.

The number of people with HIV/AIDS will grow significantly by the end of the decade. The increase will be driven by the spread of the disease in five populous countries—Nigeria, Ethiopia, Russia, India, and China—where the number of infected people will grow from around 14 to 23 million currently to an estimated 50 to 75 million by 2010. This estimate eclipses the projected 30 to 35 million cases by the end of the decade in central and southern Africa, the current focal point of the pandemic. China will have 10 to 15 million HIV/AIDS cases, and India is likely to have 20 to 25 million by 2010—the highest estimate for any country. By 2010, Nigeria will have 10 to 15 million cases, Ethiopia 7 to 10 million, and Russia 5 to 8 million.

HIV/AIDS is spreading at different rates in the five countries, with the epidemic the most advanced in Nigeria and Ethiopia. In all countries, however, risky sexual behaviors are driving infection rates upward at a precipitous rate.:*Adult prevalence rates—the total number of people infected as a percentage of the adult population—are substantially lower in Russia, India, and China, where the disease remains concentrated in high-risk groups, such as IVDA in Russia and people selling blood plasma in China, where some villages have reported 60% infection rates.:*Nevertheless, the disease is spreading to wider circles through heterosexual transmission in India, the movement of infected migrant workers in China, and frequent prison amnesty releases of large numbers of infected prison inmates and rising prostitution in Russia.

It will be difficult for any of the five countries to check their epidemics by 2010 without dramatic shifts in priorities. The disease has built up significant momentum, health services are inadequate, and the cost of education and treatment programs will be overwhelming. Government leaders will have trouble maintaining a priority on HIV/AIDS—which has been key to stemming the disease in Uganda, Thailand, and Brazil—because of other pressing issues and the lack of AIDS advocacy groups.:*The governments of Nigeria, India, and China are beginning to focus more attention on the HIV/AIDS threat.:*Even if the five next-wave countries devote more resources to HIV/AIDS programs, implementation is likely to miss significant portions of the population, given weak or limited government institutions and uneven coordination between local and national levels.:*Nigeria and Ethiopia have very limited public services to mobilize. Russia is beset by other major public health problems. China has decentralized most responsibility for health and education issues to local governments that often are corrupt.:*India has taken some steps to improve its healthcare infrastructure to combat HIV/AIDS, but the government has few resources to treat existing infections and must cope with other major health problems such as tuberculosis (TB), which has become linked to the spread of HIV/AIDS.

The rise of HIV/AIDS in the next-wave countries is likely to have significant economic, social, political, and military implications. The impact will vary substantially among the five countries, however, because of differences among them in the development of the disease, likely government responses, available resources, and demographic profiles.

:*Nigeria and Ethiopia will be the hardest hit, with the social and economic impact similar to that in the hardest hit countries in southern and central Africa—decimating key government and business elites, undermining growth, and discouraging foreign investment. Both countries are key to regional stability, and the rise in HIV/AIDS will strain their governments.:*In Russia, the rise in HIV/AIDS will exacerbate the population decline and severe health problems already plaguing the country, creating even greater difficulty for Russia to rebound economically. These trends may spark tensions over spending priorities and sharpen military manpower shortages.:*HIV/AIDS will drive up social and healthcare costs in India and China, but the broader economic and political impact is likely to be readily absorbed by the huge populations of these countries. We do not believe the disease will pose a fundamental threat through 2010 to their status as major regional players, but it will add to the complex problems faced by their leaders. The more HIV/AIDS spreads among young, educated, urban populations, the greater the economic cost of the disease will be for these countries, given the impact on, and the need for, skilled labor.

The growing AIDS problem in the next-wave countries probably will spark calls for more financial and technical support from donor countries. It may lead to growing tensions over how to disburse international funds, such as the Global Fund for AIDS, TB and Malaria.

The cost of antiretroviral drugs—which can prolong the lives of infected people—has plunged in recent years but still may be prohibitively high for low-income countries. More importantly, the drug costs are only a portion of HIV/AIDS treatment costs. Drug-resistant strains are likely to spread because of the inconsistent use of antiretroviral therapies and the manufacture overseas of unregulated, substandard drugs.:*If an effective vaccine is developed in the coming years, Western governments and pharmaceutical companies will come under intense pressure to make it widely available.:*The next-wave countries are likely to seek greater US technical assistance in tracking and combating the disease.According to UNAIDS, Asia alone is likely to outstrip Sub-Saharan Africa in the absolute number of HIV carriers by 2010.

Governments often do not spend enough money to get quality infection surveillance because they have other budget priorities, do not want to acknowledge the extent of the epidemic, and the drug users and prostitutes at high risk of infection are not key political constituencies. :*Other hidden pockets of infection include TB patients—some of whom have contracted TB because they are HIV positive—and patients with venereal diseases and reproductive tractinfections.:*It is difficult to get data on HIV prevalence rates in foreign military ranks, which harbor significant numbers of infected men.

Even if testing is available, many people do not get tested because of denial, stigma, discrimination, or resignation.:*IVDA, prostitutes, and homosexuals usually are reluctant to identify themselves for fear of punishment.:*Some avoid testing when healthcare and treatment for the disease is unavailable.


WHO declared Tuberculosis (TB) a global emergency in 1993 and the threat continues to grow, especially from multidrug resistant TB. The disease is especially prevalent in Russia, India, Southeast Asia, Sub-Saharan Africa, and parts of Latin America. Although the vast majority of TB infections and deaths occur in developing regions, the disease also is encroaching into developed regions due to increased immigration and travel and less emphasis on prevention. Drug resistance is a growing problem; the WHO has reported that up to 50 percent of people with multidrug resistant TB may die of their infection despite treatment, which can be 10 to 50 times more expensive than that used for drug-sensitive TB. HIV/AIDS also has contributed to the resurgence of TB; the immune suppression of HIV makes the patient more vulnerable to TB. One-quarter of the increase in TB incidence involves co-infection with HIV. TB probably will rank second only to HIV/AIDS as a cause of infectious disease deaths by 2020.


Thought to be coming under control in the sixties and seventies, malaria, a mainly tropical disease, is making a deadly comeback--especially in Sub-Saharan Africa where infection rates increased by 40 percent from 1970 to 1997. Drug resistance, historically a problem only with the most severe form of the disease, is now increasingly reported in the milder variety, while the prospects for an effective vaccine are poor.

Hepatitis B and Hepatitis C

Hepatitis B, which caused at least 0.6 million deaths in 1997, is highly endemic in the developing world, and some 350 million people worldwide are chronic carriers. The less prevalent but far more lethal hepatitis C identified in 1989 has grown dramatically and is a significant contributor to cirrhosis and liver cancer. WHO estimated that 3 percent of the global population was infected with the hepatitis C virus by 1997, which means that more than 170 million people were at risk of developing the diseases associated with this virus. Up to 25 percent of people with chronic hepatitis B and C will die of cirrhosis of the liver and liver cancer over the next 20 to 30 years.<

Lower respiratory infections

Lower respiratory infections, especially influenza and pneumonia, killed 3.5 million people in 1998, most of them children in developing countries, down from 4.1 million in 1993. Due to immunosuppression from malnutrition and growing bacterial resistance to antibiotics, these children are especially vulnerable to such diseases and will continue to experience high death rates. There are a few drugs effective against the influenza virus, but resistance is developing; immunization is key to control

To make each year's version of the influenza vaccine, samples of that year's mutations are necessary. Typically, the new virus strains start in Asia. Indonesia's decision to withhold samples of avian influenza virus A (H5N1) from the World Health Organization for much of 2007 caused a crisis in global health. The World Health Assembly produced a resolution to try to address the crisis at its May 2007 meeting. Indonesia refused to make samples of a virus in a local outbreak available, based on international legal principle of sovereignty and its appeal to rules on the protection of biological and genetic resources found in the Convention on Biological Diversity. The incident involving Indonesia's actions with virus samples illustrates both the importance and the limitations of international law in global health diplomacy.

Cholera and other acute gastrointestinal diseases

Diarrheal diseases--mainly spread by contaminated water or food--accounted for 2.2 million deaths in 1998, as compared to 3 million in 1993, of which about 60 percent occurred among children under five years of age in developing countries. The most common cause of death related to diarrheal diseases is infection with "Escherichia coli" ("E. coli"). Other diarrheal diseases include cholera, dysentery, and rotaviral diarrhea, prevalent throughout the developing world and, more recently, in many former communist states. Such waterborne and foodborne diseases will remain highly prevalent in these regions in the absence of improvements in water quality and sanitation. citation

Control of fecal–orally transmitted pathogens is inadequate in many developing countries, in particular, in sub-Saharan Africa. Acquired resistance to antimicrobial drugs is becoming more prevalent among "Vibrio cholerae", "Salmonella enteritidis", diarrheagenic "Escherichia coli", and other pathogens in this region. The poor, who experience most of the infections caused by these organisms, bear the brunt of extended illness and exacerbated proportion of deaths brought about by resistance. Improved antimicrobial drug stewardship is an often cited, but inadequately implemented, intervention for resistance control. Resistance containment also requires improvements in infectious disease control, access to and quality assurance of antimicrobial agents, as well as diagnostic facilities. Structural improvements along these lines will also enhance disease prevention and control as well as rational antimicrobial drug use. Additionally, more research is needed to identify low-cost, high-impact interventions for resistance control.

Oral rehydration therapy was an enormous step in treating these diseases, based on the seemingly simple, but long missed, idea that sugar is necessary for the absorption of salts and water. The availability of oral rehydration solution, which can be improvised under Third World conditions, broke through the probability of needing the skills and materials for intravenous rehydration.


While immunization is reducing the incidence, the disease still infects some 42 million children annually and killed about 0.9 million in 1998, down from 1.2 million in 1993. It is a leading cause of death among refugees and internally displaced persons. Measles will continue to pose a major threat in developing countries, particularly Sub-Saharan Africa, until the still relatively low vaccination rates are substantially increased. It also will continue to cause periodic epidemics in areas such as South America with higher, but still inadequate, vaccination rates.

According to the World Health Organization and partner agencies, there has been success with reducing the incidence of measles in Africa.citation

evere Acute Respiratory Syndrome

The outbreak of Severe Acute Respiratory Syndrome (SARS) has been overcome, but SARS has notbeen eradicated. Although WHO declared on 5 July that all transmission chains of SARS had been broken, many health experts fear it could return again in the fall when cooler temperatures return in temperate areas. We remain vulnerable.

The major concerns include::*The possible presence of animal reservoirs of the coronavirus that causes SARS :*lack of a reliable diagnostic test :*lack of a vaccine for eradication.:*If a resurgence of SARS this winter coincides with the annual outbreak of influenza, identifying and isolating suspected SARS cases will be much more difficult. SARS also could mutate, altering the symptoms, transmissibility, or lethality of the disease.:*As the first line of defense, healthcare systems and workers are particularly vulnerable. Moreover, most wealthy countries have little recent experience implementing large-scale quarantine and isolation programs, and poor countries already have inadequate health surveillance and infection control procedures.

The emergence of SARS illustrates the challenge of battling infectious diseases in anincreasingly globalized world. Global links have sped the geographic spread of the disease andamplified the economic and political impact.

The initial SARS outbreak

SARS exemplifies the potential of an infection spread through air travel. The first case of SARS was reportedly originated from a rural area in Foshan, Guangdong in Nov 2002, and the patient, a farmer, was treated in the First People's Hospital of Foshan. The patient died soon after, and no definite diagnosis was made on his cause of death. China delayed reporting this to international health organizations, and SARS spread beyond China.citation

Outside China, the first clue of the outbreak appears to be November 27, 2002 when Canada's Global Public Health Intelligence Network (GPHIN), an electronic warning system which is part of the World Health Organization's (WHO) Global Outbreak and Alert Response Network (GOARN), picked up reports of a "flu outbreak" in China through internet media monitoring and analysis and sent them to the WHO.citation

Subsequently, the WHO requested information from Chinese authorities on December 5 and 11.Heymann2004] Importantly, while GPHIN's capability had recently been upgraded to enable Arabic, Chinese, English, French, Russian and Spanish translation, the system was limited to English or French in presenting this information. Thus, while the first reports of an unusual outbreak were in Chinese, an English report was not generated until January 21, 2003."Mawadeku and Blench"]

In late April, revelations occurred as the PRC government admitted to underreporting the number of cases of SARS due to the problems inherent in the healthcare system. Dr. Jiang Yanyong exposed the coverup that was occurring in China, at great personal risk. A number of PRC officials were fired from their posts, including the health minister and mayor of Beijing, and systems were set up to improve reporting and control in the SARS crisis. Since then, the PRC has taken a much more active and transparent role in combating the SARS epidemic.

Potential of SARS recurrence

Political leadership has been a key variable in managing the epidemic. China’s efforts to hide the initial outbreak allowed SARS to build up dangerous momentum before Chinese officials became more open, while Vietnam’s willingness to promptly highlight the threat and seek international assistance helped offset the country’s weak healthcare system. The more SARS spread, the tougher countries became in implementing control measures, including quarantiningand isolating people to stop its transmission.cite web

] :*Although SARS has killed far fewer people than die each year from more common maladies such as pneumonia, influenza, malaria, tuberculosis, and HIV/AIDS, it generated significant attention and created a sense of urgency to respond because it was a mysterious new illness that seemed able to go anywhere and hit anyone.:*SARS hit parts of Asia and Canada with extensive commercial links to the rest of the world. Although the economic impact, particularly in China, was less severe than initially forecast, SARS wreaked havoc on the tourism and travel industries, erasing revenues and jobs.:*The same forces of globalization that drove the spread of SARS also have been key to managing it. Modern advances in communication, science, and travel almost certainly helped alert people more quickly to the disease, facilitated a stronger national and international response, and sped research efforts to help contain the disease.

The intense focus on SARS has opened a window of opportunity for the United States and the WHO to pursue longer-term bilateral and multilateral cooperation on health issues.

Three scenarios for SARS

The future course of SARS will depend on a host of complex variables, making forecastingdifficult. Complexity and uncertainty preclude assessing the relative likelihood of any oneof the three. SARS, even in a developed country, demands extremely careful nursing practices to avoid having the disease spread by medical personnel, according to WHO citation

date = 24 April 2003

] Countries that lack the necessary respirators and other barrier nursing equipment can risk spread.

The first scenarion is "SARS Simmers": SARS could resurface but be limited to random outbreaks in a few countries, rendering it more of a public health nuisance than a crisis. Political and economic reverberations still would occur, with some companies and investors looking to reduce their exposure in East Asia, particularly China.

The next alternative is that "SARS Gains a Foothold in Poor Countries, Regions. SARS could spread to poor countries in Africa or Asia, potentially generating more infections and deaths than before but with relativelylittle international economic impact. The risk of spread would continue, however, even if SARSemerged in poor countries or isolated regions of Russia and China with weak healthcare systems. WHO and CDC probably would come under intense pressure to provide money and technical assistance to compensatefor weak healthcare systems.

Some isolated countries such as North Korea probably would resist outside assistance, even at the risk of putting their own citizens at risk and requiring the US to improve its medical intelligence collection to protect its own and allied forces.citation

] Some repressive regimes hit by SARS are likely to employ brutal tactics to quarantine and isolate people, possibly sowing division among outside countries and multilateral organizations over how to respond to apparent human rights violations.

The worst case is a full resurgence of SARS could come back in the places it hit before—such as China, Taiwan, Canada, and Singapore—or hit harder in other well-connected places like the United States, Japan, Europe, India, or Brazil. Even if the number of infected persons were not significantly greater, the resurgence of the disease in globally linked countries probably would generate a significant impact again. The return of SARS to Asia is likely to cause somewhat less disruption the second time as citizens learn to live with the disease, but more multinational companies probably would reduce their exposure in the region if they concluded that SARS posed a long-term health challenge. Bigger outbreaks in Europe or the United States would hit a whole new set of business and government players, potentially doing serious damage to trade and growth.
