In 1970, Brazil implemented the Schistosomiasis Control Program (PCE, Portuguese acronym for Programa de Controle da Esquistossomose) was implemented in Brazil, where, through successive treatment interventions, the epidemiology and transmission of schistosomiasis have changed significantly over time. This study aimed to evaluate the PCE's effectiveness by critically analyzing the disease notification system.
An ecological study was conducted using data on reported schistosomiasis cases in Brazil between 2007 and 2020.
The highest number of municipalities actively participating in the PCE was 750, recorded in 2007. Conversely, participation reached its lowest point in 2020, with only 259 municipalities involved. Over the past decade, there has been a drastic decline in the number of municipalities with active schistosomiasis control programs. During the same period, there was an observed increase in the number of deaths caused by schistosomiasis, while the number of reported cases decreased. This suggests an inverse correlation.
The present data suggest that schistosomiasis cases are not correctly diagnosed or reported, reflecting a twisted image of the magnitude of this public health problem in Brazil.
1970 年，巴西实施了血吸虫病控制计划（PCE），随着时间的推移，通过连续的治疗干预，血吸虫病的流行病学和传播发生了显著变化。本研究旨在通过批判性分析疾病报告系统来评估 PCE 的有效性。
使用 2007 年至 2020 年巴西报告的血吸虫病病例数据进行了一项生态学研究。
2007 年，有 750 个市积极参与 PCE，这是参与度最高的一年。相反，2020 年的参与度达到了最低点，只有 259 个市参与。在过去十年中，积极开展血吸虫病控制项目的市数量急剧下降。同期，血吸虫病死亡人数有所增加，而报告病例数则有所减少。这表明两者呈负相关。
目前的数据表明，血吸虫病病例并未得到正确诊断或报告，这反映了巴西这一公共卫生问题的严重程度被扭曲了。
