房屋改善和环境管理可以显著改善疟疾流行社区的疟疾传播控制。这项研究评估了房屋和周围环境的物理特征对坦桑尼亚农村地区蚊子叮咬风险的影响，并调查了居民对这些因素与疟疾传播之间关系的知识和看法。这项研究进一步评估了人们是否担心这些风险以及他们是如何应对的。对坦桑尼亚东南部乌兰加地区的四个村庄进行了室内蚊子密度的昆虫学调查。这项调查包括每月抽样的48套哨所和其他每月随机抽取的48套住房，在12个月的时间里进行一次性抽样。记录了房屋和周围环境的物理特征。对200名户主进行了问卷调查，以评估他们对观察到的住房和环境特征的了解和关注，以及他们在建造房屋时是否考虑了这些特征。进行了焦点小组讨论，以澄清人们对住房或环境因素与疟疾传播之间的关系的看法的新主题。昆虫学调查显示，与抹灰或砖墙相比，泥墙房屋的室内传播疟疾媒介(阿拉伯按蚊和按蚊)的密度更高，与关闭的屋檐相比，敞开的屋檐比关闭的屋檐，与纱窗相比，未加纱窗的房子的室内疟疾媒介密度更高。大多数受访者报告说，他们的房子允许蚊子进入，至少部分允许。与会者意识到，房屋结构和环境特征影响室内蚊子密度，从而影响疟疾传播。他们担心住在屋檐、墙壁、窗户和门上有缺口的劣质房屋，但受到低收入的制约。在坦桑尼亚东南部的农村，相当大一部分人仍然住在屋檐敞开、窗户没有遮挡、门上有缝隙的房子里。尽管他们充分意识到与蚊子叮咬和病原体传播相关的风险，但他们受到低收入水平的制约。该研究提出，以社区为基础的住房改善倡议与有针对性的补贴相结合，可以降低资金障碍，改善获得基本建筑材料或设计的机会，并显著加快这些社区的疟疾传播控制。
House improvement and environmental management can significantly improve malaria transmission control in endemic communities. This study assessed the influence of physical characteristics of houses and surrounding environments on mosquito biting risk in rural Tanzanian villages, and examined knowledge and perceptions of residents on relationships between these factors and malaria transmission. The study further assessed whether people worried about these risks and how they coped. Entomological surveys of indoor mosquito densities were conducted across four villages in Ulanga district, south-eastern Tanzania. The survey involved 48 sentinel houses sampled monthly and other sets of 48 houses randomly recruited each month for one-off sampling over 12 months. Physical characteristics of the houses and surrounding environments were recorded. Questionnaire surveys were administered to 200 household heads to assess their knowledge and concerns regarding the observed housing and environmental features, and whether they considered these features when constructing houses. Focus group discussions, were conducted to clarify emergent themes on people’s perceptions on relationships between housing or environmental factors and malaria transmission. The entomological surveys showed statistically higher indoor densities of the malaria vectors (Anopheles arabiensis and Anopheles funestus) in houses with mud walls compared to plastered or brick walls, open eaves compared to closed eaves and unscreened windows compared to screened windows. Most respondents reported that their houses allowed mosquito entry, at least partially. Participants were aware that house structure and environmental characteristics influenced indoor mosquito densities and consequently malaria transmission. They were concerned about living in poorly-constructed houses with gaps on eaves, walls, windows and doors but were constrained by low income. In rural south-eastern Tanzania, significant proportions of people still live in houses with open eaves, unscreened windows and gaps on doors. Though they are fully aware of associated mosquito biting and pathogen transmission risks, they are constrained by low-income levels. The study proposes that community-based house improvement initiatives combined with targeted subsidies could lower the financial barriers, improve access to essential construction materials or designs, and significantly accelerate malaria transmission control in these communities.
