BACKGROUND: To analyze the epidemiology, surveillance, and control strategies for trachoma in the state of Ceará, northeast Brazil, from 2007 to 2021. METHODS: This ecological study was based on secondary data from the Information System on Notifiable Diseases of the Secretary of Health of the state of Ceará. Data from school and home surveys for trachoma detection obtained during the study period were analyzed, the percentage of positivity was estimated, and sociodemographic and clinico-epidemiological factors were investigated. RESULTS: The coverage of trachoma surveillance and control actions in Ceará municipalities increased from 12.5% in 2007 to 55.9% in 2019, but with an average restriction of 8.0% during the COVID-19 pandemic. The estimated trachoma positivity (mean overall positivity) was less than 5.0% (2.76%, 95% CI 1.2-5.2), with a higher proportion of cases in the 5-9-year age group (45.0%, 95% CI 44.6-45.4), in females (53.2%, 95% CI 52.8-53.6), and rural areas (52.6%, 95% CI 52.2-53.0). Positivity above 10.0% was observed in the Litoral Leste/Jaguaribe and Sertão Central regions, with a higher occurrence of the follicular inflammatory clinical form (98.1%, 95% CI 98.0-98.2). CONCLUSIONS: Trachoma remains in the state of Ceará and is likely underreported. Despite recent advances, the fragility of health surveillance activities compromises the recognition of the actual magnitude and distribution of trachoma in the state. Accurate information is fundamental for planning, monitoring, and evaluating surveillance and disease control.
背景:分析 2007 年至 2021 年巴西东北部塞阿拉州沙眼的流行病学、监测和控制策略。
方法:本生态研究基于塞阿拉州卫生局传染病报告信息系统的二级数据。分析了研究期间通过学校和家庭沙眼检测调查获得的数据,估计了阳性率,并调查了社会人口统计学和临床流行病学因素。
结果:塞阿拉州各城市沙眼监测和控制行动的覆盖率从 2007 年的 12.5%增加到 2019 年的 55.9%,但在 COVID-19 大流行期间平均限制了 8.0%。估计的沙眼阳性率(总体平均阳性率)低于 5.0%(2.76%,95%CI 1.2-5.2),5-9 岁年龄组的病例比例较高(45.0%,95%CI 44.6-45.4),女性(53.2%,95%CI 52.8-53.6)和农村地区(52.6%,95%CI 52.2-53.0)。在东海岸/Jaguaribe 和中央内陆地区观察到阳性率超过 10.0%,滤泡性炎症临床形式的发生率更高(98.1%,95%CI 98.0-98.2)。
结论:沙眼仍在塞阿拉州流行,且可能报告不足。尽管最近有所进展,但卫生监测活动的脆弱性仍会影响对该州沙眼实际规模和分布的认识。准确的信息是规划、监测和评估监测和疾病控制的基础。
