title: Acute haemorrhagic conjunctivitis in Soweto, 1982. An epidemiological investigation.
abstract: In mid-March 1982 an epidemic of acute haemorrhagic conjunctivitis (AHC) broke out in Soweto. Over 34 000 people were treated before the epidemic subsided some 13 weeks later, the overall attack rate being 34,1/1 000. The records of 3 945 patients seen at St John's Eye Hospital were analysed, and the populations at greatest risk of contracting the disease were identified. Males were at greatest risk, with a male to female attack rate ratio of 1,8:1. The age-specific attack rates for both sexes show a similar pattern, peaking in the young adult age groups.
