我们评估了当地气象和环境条件、室内残留喷洒杀虫剂、个人和社区层面使用杀虫剂处理过的蚊帐（ITNs）以及个体因素对埃塞俄比亚南部一个村庄恶性疟原虫疟疾发病率的潜在影响。对8121人进行了为期101周的主动和被动监测。在317例显微镜确诊的恶性疟原虫病例中，29.3%发生在临时居民中。发病密度为3.6/ 10000人-周观察。我们观察到，男性、5-14岁儿童、未使用蚊帐的人、穷人和居住在离病媒滋生地较近的人群中疟疾发病率较高。降雨量增加，室内滞留喷洒溴氰菊酯降低了恶性疟发病率。虽然蚊帐对使用者预防了恶性疟疾，但我们没有发现免费大规模分发蚊帐在村庄一级减少了恶性疟疾。
We assessed potential effects of local meteorological and environmental conditions, indoor residual spraying with insecticides, insecticide-treated nets (ITNs) use at individual and community levels, and individual factors on Plasmodium falciparum malaria incidence in a village in south Ethiopia. A cohort of 8,121 people was followed for 101 weeks with active and passive surveillance. Among 317 microscopically confirmed P. falciparum malaria episodes, 29.3% occurred among temporary residents. The incidence density was 3.6/10,000 person-weeks of observation. We observed higher malaria incidence among males, children 5-14 years of age, ITNs non-users, the poor, and people who lived closer to vector breeding places. Rainfall increased and indoor residual spraying with Deltamethrin reduced falciparum incidence. Although ITNs prevented falciparum malaria for the users, we did not find that free mass ITNs distribution reduced falciparum malaria on a village level.
