title: The prevalence of trachoma in preschool and school children in Olimpia, Guaraci and Cajobi, Sao Paulo, Brazil.
abstract: A school-based prevalence survey of trachoma was conducted in three rural municipalities in the state of Sao Paulo, Brazil, in 1989. A total of 950 children aged 4-11 years were examined. The prevalence of inflammatory trachoma was found to be 6.3%, peaking at 24.1% in the 4 year-old age group. The prevalence of trachomatous scarring was 2.7% and was more prevalent in older children. Risk factors included household sleeping arrangements and nasal discharge.
