The seroprevalence of Chagas disease in humans and the presence of triatomines were investigated in a rural locality in the State of Ceará, Brazil, an historically endemic region. Approximately 80% of the surveyed residents agreed to undergo serological tests. Intradomestic and peridomestic environments were searched for triatomines in both the dry and rainy seasons. The prevalence rate of Chagas disease was 1.2% and the majority of individuals confirmed with the disease over 50 years of age. A total of 761 specimens of triatomines were captured, most of which were from colonies composed of nymphs and adult bugs, and the majority of specimens were obtained in the dry season. Triatoma brasiliensis was the predominant species. Analysis using light microscopy revealed that 28.6% of the insects were Trypanosoma cruzi positive. Results suggest that peridomestic man-made structures, such as animal shelters, improper storage of timber and uninhabited dwellings contribute to the high rate of triatomine infestation in the area.
在巴西塞阿拉州一个历史上的地方病流行农村地区，对人类恰加斯病的血清流行率和锥蝽的存在情况进行了调查。大约80%的受访居民同意接受血清学检测。在旱季和雨季，对家庭内部和周边环境进行了锥蝽搜索。恰加斯病的患病率为1.2%，大多数确诊病例为50岁以上的个体。共捕获761只锥蝽标本，其中大部分来自若虫和成虫组成的群体，且大部分标本是在旱季获得的。巴西锥蝽是主要种类。光学显微镜分析显示，28.6%的昆虫克氏锥虫呈阳性。结果表明，家庭周边的人造建筑，如动物庇护所、木材储存不当和无人居住的房屋，导致了该地区锥蝽的高感染率。
