To estimate the prevalence of Chagas disease, Hansen disease and schistosomiasis among residents of rural productive villages of the São Francisco River Integration Project in Ceará and to verify the presence, species and positivity of triatomines for Trypanosoma cruzi.
This is a descriptive cross-sectional study conducted in the productive villages located in Jati, Brejo Santo and Mauriti, based on a clinical-epidemiological, serological and parasitological survey for schistosomiasis, Chagas disease and Hansen disease; and a triatomine survey. The descriptive analysis was composed by calculating absolute and relative frequencies with 95% confidence intervals.
The prevalence of schistosomiasis was 0.97% (2/206) by the Kato-Katz method and 11.54% (27/234) by the Immunochromatographic POC-CCA Test method. For Chagas disease, the prevalence was 0.27% (1/368). The suspected cases of Hansen disease through dermato-neurological examination comprised 2.67% (8/300) of the subjects, none of which were subsequently confirmed. Among the 245 household units investigated, triatomines were identified in 4 them (1.63%) (6 Triatoma pseudomaculata and 1 Panstrongylus megistus), but none with the presence of Trypanosoma cruzi.
Chagas disease and schistosomiasis persist as endemic in these study areas. Even without the identification of triatomines infected by T. cruzi and of Hansen disease cases, the context of the region reinforces the need for continuous surveillance. It is essential to implement integrated public health actions to combat different neglected tropical diseases in new territories of human occupation. Contexts of endemicity and vulnerability make it essential to strengthen this topic on municipal and state public agendas.
评估塞阿拉州圣弗朗西斯科河综合开发项目农村生产性村庄居民中恰加斯病、麻风病和血吸虫病的患病率，并核查锥蝽感染克氏锥虫的情况、种类及阳性率。
这是一项描述性横断面研究，在位于贾蒂、布雷茹圣托和毛里蒂的生产性村庄开展，基于对血吸虫病、恰加斯病和麻风病的临床流行病学、血清学及寄生虫学调查；以及锥蝽调查。描述性分析包括计算绝对频率和相对频率以及95%置信区间。
采用加藤-卡茨法，血吸虫病患病率为0.97%（2/206），采用免疫层析即时检测法（POC-CCA）患病率为11.54%（27/234）。恰加斯病患病率为0.27%（1/368）。经皮肤-神经学检查疑似麻风病的病例占受试者的2.67%（8/300），但随后均未确诊。在调查的245个家庭单元中，在4个单元发现了锥蝽（1.63%）（6只伪黄斑锥蝽和1只大长红猎蝽），但均未感染克氏锥虫。
恰加斯病和血吸虫病在这些研究地区仍为地方病。即使未发现感染克氏锥虫的锥蝽和麻风病病例，该地区的情况仍凸显持续监测的必要性。在新的人类居住地区实施综合公共卫生行动以防治不同的被忽视热带病至关重要。地方病和脆弱性背景使得在市和州公共议程中强化这一议题必不可少。
