恰加斯病是由克氏锥虫引起的，它主要由在建造不良的房屋中寻找有利环境的锥虫虫的粪便传播。先前的研究表明，尽管多次使用杀虫剂和进行教育干预，但厄瓜多尔南部Loja省的房屋中仍存在狐螨病。我们的目标是制定一项可持续战略，通过促进旨在防止锥蝽在农村房屋中殖民的生活环境，阻断恰加斯病的传播。本研究通过识别未使用triatomine的家庭所使用的知识、态度和实践（2010-2012），利用积极偏差为反triatomine原型房屋的设计提供信息。积极的越轨者报告的做法包括维护房屋的结构要素，对住宅和动物收容所进行熏蒸，用“驱虫”植物清扫，以及将家畜从房子里移走等等。参与者喜欢与目前使用的建筑材料（土坯墙和瓦屋顶）没有太大区别的建筑材料。他们还表示，他们相信干净的房子和健康之间有着明确的联系。家庭的经济动态影响空间的使用，在原型设计中必须考虑到这一点。总的来说，结果表明，在该地区，作为防治恰加斯病的一项保护措施，改善住房的气氛是积极的。
Chagas disease is caused by Trypanosoma cruzi, which is mainly transmitted by the faeces of triatomine insects that find favourable environments in poorly constructed houses. Previous studies have documented persistent triatomine infestation in houses in the province of Loja in southern Ecuador despite repeated insecticide and educational interventions. We aim to develop a sustainable strategy for the interruption of Chagas disease transmission by promoting living environments that are designed to prevent colonisation of rural houses by triatomines. This study used positive deviance to inform the design of an anti-triatomine prototype house by identifying knowledge, attitudes and practices used by families that have remained triatomine-free (2010-2012). Positive deviants reported practices that included maintenance of structural elements of the house, fumigation of dwellings and animal shelters, sweeping with "insect repellent" plants and relocation of domestic animals away from the house, among others. Participants favoured construction materials that do not drastically differ from those currently used (adobe walls and tile roofs). They also expressed their belief in a clear connection between a clean house and health. The family's economic dynamics affect space use and must be considered in the prototype's design. Overall, the results indicate a positive climate for the introduction of housing improvements as a protective measure against Chagas disease in this region.
