was first observed in 1883 by Koch, a German bacteriologist. As a member of the German Cholera Commission of Egypt, Koch studied 50 patients suffering from Egyptian eye disease
After the study, he discovered the disease was caused by two bacteria, one of which was Haemophilus aegyptius. H. ageyptius was the more benign form but it had not been named at that time. Three years later, Weeks published a paper detailing the essential characteristics of H. aegyptius.
During the mid-1980s to early 1990s, a highly virulent clonal group of Haemophilus aegyptius was found responsible for Brazilian purpuric fever, an acute septicemic fulminant illness affecting children.
