- Panzootic
A panzootic (from Greek παν "pan" all + ζόιον "zoion" animal) is an
epizootic (an outbreak of aninfectious disease of animals) that spreads across a large region (for example a continent), or even worldwide. The equivalent inhuman populations is called apandemic .A panzootic can start when three conditions have been met:
* the emergence of a disease new to the population.
* the agent infects a species and causes serious illness.
* the agent spreads easily and sustainably among animals.A disease or condition is not a panzootic merely because it is widespread or kills a large number of animals; it must also be infectious. For example
cancer is responsible for a large number of deaths but is not considered a panzootic because the disease is, generally speaking, not infectious.
=Avian flu and zoonoticepidemiology =In February
2004 ,avian influenza virus was detected in birds inVietnam , increasing fears of the emergence of new variant strains. It is feared that if the avian influenza virus combines with a human influenza virus (in a bird or a human), the new subtype created could be both highly contagious and highly lethal.In October 2005, cases of the avian flu (the deadly strain
H5N1 ) were identified inTurkey . EU Health Commissioner Markos Kyprianou said: "We have received now confirmation that the virus found in Turkey is an avian flu H5N1 virus. There is a direct relationship with viruses found in Russia, Mongolia and China." Cases of bird flu were also identified shortly thereafter inRomania , and thenGreece . Possible cases of the virus have also been found inCroatia ,Bulgaria and in theUnited Kingdom . [http://news.bbc.co.uk/1/hi/world/europe/4348404.stm] . However, by the end of October only 67 people had died as a result of H5N1 which was atypical of previous influenza pandemics.ee also
