"Haemophilus influenzae" biogroup "aegyptius" ("Hae") is a causative agent of conjunctivitis. It was discovered independently by Koch and Weeks in the 1880s. In and around the São Paulo State of Brazil during the mid 1980s to early 1990s a highly virulent clonal group of "Hae" was found to be responsible for Brazilian purpuric fever, an acute septacaemic fulminant illness of children.
