On January 24, two men butchered a dead chimpanzee they found
dead in the forest. On February 5-6, 19 original cases showed signs of EHF
(high fever, bloody diarrhea, and severely reddened eyes) and were admitted
to Makokou provincial hospital. The average age of the 19 original patients
was 18 years. Rapid identification and the implementation of appropriate control
measures brought the outbreak quickly under control and prevented further
amplification. The last case of EHF died on 12 March 1996. Outbreak officially
declared over by the WHO (World Health Organization) on 23 April 1996; 42
days (twice the incubation period) after the last EHF patient death. Total
number of EHF cases was 37 (17 females, 20 males), and the mean age of the
EHF patients was 27 years (range seven months to 70 years).
