Abstract
Nine hundred and sixteen people from 143 randomly selected households were included in this community-based investigation of an outbreak of acute viral conjunctivitis in urban slum communities of Delhi in 1994. During the 2-weeks recall period, 456 (49.8%) had conjunctivitis and 229 (25%) were symptomatic at the time of this investigation. Overall, females had a higher attack rate than males (P < 0.05). The attack rate increased with age (P < 0.001). A total of 61.6% of the conjunctival swabs were antigen positive as evidenced by indirect immunofluorescence assay. Viruses could be isolated from 30.3% of the samples processed. Out of these, 70% were identified as Coxsackie A 24 and 30% as EV 70.
