Trachoma in a rural Haitian community.
We selected 43 patients, aged 15 days to 57 yesrs, for intensive study after screening 975 people for clinical evidence of trachoma in rural Haiti. Trachoma was present in Haiti with low endemicity and was followed by relatively mild sequelae. Laboratory studies confirmed the disease through demonstration of conjunctival inclusion bodies by immunofluoresence and serotyping of antibody in sera or eye secretions, or both. Of 23 patients (age 1 to 36 years) with active trachoma, all had serum antibody to chlamydia (range 1:10 to 1:640), nine had eye secretion antibody (range 1:10 to 1:1280), and one was inclusion positive. The remaining 20 patients (age 15 days to 57 years) had the following diagnosis: atypical follicles (eight), conjunctivitis with or without mucopurulent discharge (ten) innactive pannus only (one), and severe anemia (one). Only 16 of the 20 were tested for serum antibody and all were positive (1:10 to 1:5,120), 11 of 20 had eye secretion antibody (1:10 to less than or equal to 1:640), and one was inclusion positive. Serotyping attempted on 22 patients yielded 16 patients with antibodies specific for type A, one patient with type B, and five who were not typed.
