城市地区的大多数病媒控制活动侧重于家庭环境；然而，与家庭以外的空间感染风险有关的信息很少，这些空间所代表的相对风险尚未得到充分了解。我们使用数据驱动的模拟来调查家庭和非家庭环境对登革热昆虫学风险的重要性，在两个报告了登革热传播的肯尼亚城市。现场工作使用了四种针对不同阶段蚊子的策略：诱卵器、幼虫收集、Prokopack吸入法和BG哨兵诱捕器。分别分析家庭和非家庭环境中的数据，以评估蚊子的存在、收集的媒介数量和媒介存在的风险因素。利用这些数据，我们模拟了媒介种群和人类种群，以估计家庭和非家庭环境中的参数m和蚊子与人的密度。在分析的变量中，主要差异是蚊子丰度，在基苏木的非家庭环境中蚊子丰度一直较高，但在乌昆达类似。风险因素分析表明，家庭中与水有关的小型容器是蚊子滋生的地方，而不是非家庭结构中与垃圾和降雨有关的容器。我们发现，在基苏木的非家庭环境中，媒介密度(M)高于家庭环境，在乌昆达，两种环境之间的媒介密度(M)也相似或略低。这些结果表明，由于媒介丰富，在非家庭环境中存在潜在的传播风险；因此，媒介控制活动应考虑到这些空间。
Most vector control activities in urban areas are focused on household environments; however, information relating to infection risks in spaces other than households is poor, and the relative risk that these spaces represent has not yet been fully understood. We used data-driven simulations to investigate the importance of household and non-household environments for dengue entomological risk in two Kenyan cities where dengue circulation has been reported. Fieldwork was performed using four strategies that targeted different stages of mosquitoes: ovitraps, larval collections, Prokopack aspiration, and BG-sentinel traps. Data were analyzed separately between household and non-household environments to assess mosquito presence, the number of vectors collected, and the risk factors for vector presence. With these data, we simulated vector and human populations to estimate the parameter m and mosquito-to-human density in both household and non-household environments. Among the analyzed variables, the main difference was found in mosquito abundance, which was consistently higher in non-household environments in Kisumu but was similar in Ukunda. Risk factor analysis suggests that small, clean water-related containers serve as mosquito breeding places in households as opposed to the trash- and rainfall-related containers found in non-household structures. We found that the density of vectors (m) was higher in non-household than household environments in Kisumu and was also similar or slightly lower between both environments in Ukunda. These results suggest that because vectors are abundant, there is a potential risk of transmission in non-household environments; hence, vector control activities should take these spaces into account.
