Abstract
Introduction: Epidemiological surveillance activities undertaken after the detection of an active trachoma case in the APAE-SP are described.
Material and Method: A total of 1,009 pupils, employees and household contacts had an eye examination. Treatment control was carried out at the institution 4 times at 45 day-intervals.
Results: The overall prevalence was of 5.9%, 5.1% being of follicular trachoma (TF), 0.3% of intense trachoma (TF/TI) and 0.5% of cicatricial trachoma (TS). At the first control exercise 45.5% of the trachoma cases had no signs of the disease and 40.0% underwent treatment. At the last control exercise 20% were found to have been cured with no vestigial scars. Non-attendance was of 38.2%. The distribution of secondary cases showed great dispersion, suggesting dissemination throughout Greater S. Paulo.
Discussion and Conclusions: The trachoma control activities do not show satisfactory results, perhaps due to the prolonged duration of the treatment and follow-up. The development of strategies of clinical intervention should be implemented for better control of the disease.
