With the climate changing and worsening rainfall patterns, dengue, and its vector, the Aedes spp. mosquito, are becoming an urgent matter both in Colombia and globally. The limited availability of vaccines for this arbovirus, combined with the risk of severe disease with each reinfection, means that dengue control primarily relies on targeted vector control tailored to specific areas. This study aims to analyze the social perceptions and environmental risk factors that affect mosquito presence and dengue acquisition in Restrepo, Meta, Colombia. A knowledge, attitudes and practices questionnaire, and focus groups were conducted in communities of Restrepo, and entomological indexes were calculated for the municipality. Quantitative and qualitative analysis were performed. Participants had good knowledge of arbovirus infections, but lacked specific knowledge about transmission and how best to protect themselves. Those knowledgeable of cleaning water tanks were 0.28 times as likely to have mosquitos trapped in their house than those who did not. By contrast, those that reported using bed nets were more likely to have mosquitoes in their house than those who did not, potentially due to an overestimated sense of protection or need to use a net because of their presence. There was little reported community organization to control Aedes mosquitos, and social stratum was determined to be a risk factor for mosquito presence. Participants were in favor of interventions by the Health Secretariat, especially insecticide spraying. Our findings identify areas of need for education and engagement initiatives: encouraging community responsibility and day-time bite prevention measures may empower residents to protect themselves better. This can help the Health Secretariat to guide promotion and prevention strategies by knowing the sociodemographic characteristics and popular knowledge of the inhabitants of the city of Restrepo.
随着气候变化和降雨模式恶化，登革热及其病媒伊蚊在哥伦比亚乃至全球都成为了紧迫问题。这种虫媒病毒疫苗供应有限，再加上每次再次感染都有患重病的风险，这意味着登革热防控主要依赖于针对特定区域量身定制的病媒控制措施。本研究旨在分析影响哥伦比亚梅塔省雷斯特雷波市蚊子滋生和登革热感染的社会认知及环境风险因素。在雷斯特雷波市的社区开展了知识、态度和行为问卷调查以及焦点小组讨论，并计算了该市的昆虫学指标。进行了定量和定性分析。参与者对虫媒病毒感染有一定了解，但缺乏关于传播方式以及如何最佳保护自己的具体知识。了解清洁水箱的人家里诱捕到蚊子的可能性是不了解的人的0.28倍。相比之下，报告使用蚊帐的人家里有蚊子的可能性比不使用的人更大，这可能是由于保护意识过高，或者因为有蚊子而需要使用蚊帐。报告显示几乎没有社区组织来控制伊蚊，社会阶层被确定为蚊子滋生的一个风险因素。参与者支持卫生秘书处的干预措施，尤其是杀虫剂喷洒。我们的研究结果确定了教育和参与倡议的需求领域：鼓励社区责任感和白天防蚊措施可能会使居民更好地保护自己。这有助于卫生秘书处通过了解雷斯特雷波市居民的社会人口特征和大众知识来指导推广和预防策略。
