Epidemiological surveillance activities undertaken after the detection of an active trachoma case in the APAE-SP are described.
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.
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.
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.
描述了在圣保罗市APAE地区发现活动性沙眼病例后开展的流行病学监测活动。
共有1009名学生、员工及家庭接触者接受了眼部检查。在该机构每隔45天进行4次治疗控制。
总体患病率为5.9%，其中滤泡性沙眼（TF）占5.1%，重度沙眼（TF/TI）占0.3%，瘢痕性沙眼（TS）占0.5%。在首次控制检查时，45.5%的沙眼病例无疾病体征，40.0%接受了治疗。在最后一次控制检查时，发现20%已治愈且无残留瘢痕。未就诊率为38.2%。二代病例的分布显示出很大的分散性，表明沙眼在大圣保罗地区广泛传播。
沙眼控制活动未显示出令人满意的结果，可能是由于治疗和随访时间过长。应实施临床干预策略以更好地控制该疾病。
