控制恰加斯病需要控制其锥蝽载体，这需要了解感染的决定因素。对莫雷洛斯州 Chalcatzingo 镇的 27 个家庭环境特征进行了分析，以确定其与当地主要病媒苍白锥蝽 (Triatoma pallidipennis) 感染的关系。数据是通过定时家庭搜索锥蝽以及对住所内和住所周围环境进行表征的调查获得的。在接受调查的家庭中，28.4%的家庭受到苍白毛蝽感染。进行横断面多元逻辑回归分析，对环境变量的感染进行回归。全镇530户家庭中，84%的家庭有足够的数据纳入其中。土坯墙、农产品、垃圾堆、缺乏蚊帐和兔子数量与家庭内感染显着相关。垃圾堆以及狗、猫和兔子的数量与家庭周围感染显着相关。垃圾堆、农产品以及猫、兔子和鸟类的数量与总体感染显着相关。出乎意料的是，石堆的存在与感染无关。这项研究的结果为在受苍白锥虫感染的墨西哥农村地区设计南美锥虫病控制计划提供了信息。
Control of Chagas disease requires control of its triatomine vectors, which requires an understanding of the determinants of infestation. Twenty-seven household environmental characteristics in the town of Chalcatzingo, Morelos, were analyzed for association with infestation by Triatoma pallidipennis, the predominant local vector. Data were obtained through timed household searches for triatomines and surveys that characterized intradomicile and peridomicile environments. Of the households surveyed, 28.4% were infested by T pallidipennis. Cross-sectional multivariate logistic regression analyses were performed that regressed infestation on environmental variables. Of the 530 households in the town, 84% had sufficient data to be included. Adobe walls, agricultural products, junk piles, lack of bednets, and number of rabbits were significantly associated with intradomiciliary infestation. junk piles and numbers of dogs, cats, and rabbits were significantly associated with peridomiciliary infestation. junk piles, agricultural products, and numbers of cats, rabbits, and birds were significantly associated with overall infestation. Unexpectedly, presence of stone piles was not associated with infestation. The results of this study provide information for designing Chagas disease control programs in rural Mexican areas infested by T pallidipennis.
