在撒哈拉以南非洲，凉爽房屋将扩大经杀虫剂处理的蚊帐的覆盖面，这是控制疟疾的主要工具。我们研究了是否改善通风，使用窗户与网屏蔽，冷却房屋在夜间和减少疟疾蚊子进入冈比亚的房子。建造了相同的房屋，门不合适是蚊子唯一的入口。两个人睡在每个房子里，用灯光捕捉蚊子。首先，在四个有0，1，2和3个纱窗的房子里比较温度和蚊子密度。第二，二氧化碳（CO2），一种主要的蚊子引诱剂，在房屋中测量（i）没有窗户，（ii）纱窗和（iii）纱窗和纱门。计算流体动力学模型捕捉了二氧化碳的空间运动。增加通风使房屋更凉爽，更舒适，并减少疟疾蚊子进入房屋;三个窗户使蚊子密度降低95%（95%CI = 90-98%）。纱窗和门使室内温度降低0.6°C（95%CI = 0.5-0.7°C），室内CO2浓度在21.00和00.00 h之间降低31%，疟疾蚊子进入降低76%（95%CI = 69-82%）。模型显示，筛选减少了房屋的二氧化碳羽流。在我们的实验条件下，交叉通风不仅降低了室内温度，而且通过减弱房屋散发的二氧化碳烟流来减少进入房屋的疟疾蚊子的密度。
In sub-Saharan Africa, cooler houses would increase the coverage of insecticide-treated bednets, the primary malaria control tool. We examined whether improved ventilation, using windows screened with netting, cools houses at night and reduces malaria mosquito house entry in The Gambia. Identical houses were constructed, with badly fitting doors the only mosquito entry points. Two men slept in each house and mosquitoes captured using light traps. First, temperature and mosquito density were compared in four houses with 0, 1, 2 and 3 screened windows. Second, carbon dioxide (CO2), a major mosquito attractant, was measured in houses with (i) no windows, (ii) screened windows and (iii) screened windows and screened doors. Computational fluid dynamic modelling captured the spatial movement of CO2. Increasing ventilation made houses cooler, more comfortable and reduced malaria mosquito house entry; with three windows reducing mosquito densities by 95% (95%CI = 90–98%). Screened windows and doors reduced the indoor temperature by 0.6°C (95%CI = 0.5–0.7°C), indoor CO2 concentrations by 31% between 21.00 and 00.00 h and malaria mosquito entry by 76% (95%CI = 69–82%). Modelling shows screening reduces CO2 plumes from houses. Under our experimental conditions, cross-ventilation not only reduced indoor temperature, but reduced the density of house-entering malaria mosquitoes, by weakening CO2 plumes emanating from houses.
