Household distribution of seroreactivity to Trypanosoma cruzi in inhabitants was analyzed in relation to house construction and the distribution of Panstrongylus megistus, the principal domestic vector of Chagas' disease in a rural area in northeast Brazil. No children residing in mud-brick houses were seroreactive to T. cruzi. The highest rates of seroreactivity occurred in residents of unplastered mud-stick houses, and were twice as high as those found in persons living in mud-brick houses or plastered mud-stick houses. Two-thirds of seroreactive children in this area resided in unplastered mud-stick houses. Over 90% of the P. megistus infestations were found in mud-stick houses. Mud-brick houses had the lowest infestation rates of P. megistus and the lowest household rates of seroreactivity to T. cruzi.
针对巴西东北部农村地区恰加斯病的主要家庭传播媒介——大锥猎蝽的分布情况以及房屋建造情况，对当地居民锥虫血清反应性的家庭分布进行了分析。居住在土坯房中的儿童对克氏锥虫无血清反应。血清反应性发生率最高的是居住在未抹灰泥的泥棒房中的居民，是居住在土坯房或抹灰泥的泥棒房中的居民的两倍。该地区三分之二有血清反应的儿童居住在未抹灰泥的泥棒房。超过90%的大锥猎蝽感染发生在泥棒房。土坯房的大锥猎蝽感染率最低，对克氏锥虫的家庭血清反应率也最低。
