本研究比较了冈比亚Farafenni地区使用蚊帐与不用蚊帐的儿童与疟疾发病率的关系。从脾肿率与疟原虫检出率的对比来看,蚊帐对疟疾有明显的防护作用。调查选择了冈比亚河北岸疟疾流行区自然环境相同的41个村庄,总人数12 313人。按1:5随机抽样挑选7岁以下儿童600人,每月随访调查发病情况,对体温≥37.5℃者作系统观察并采制血片。到当年雨季结束时,医生检查各组儿童,并采血进行血液学、寄生虫学与血清学的研究,调查蚊帐使用情
This study compared the incidence of malaria in children living with and without mosquito nets in Farafenni, Gambia. From the splenomegaly and malaria parasite detection rate comparison, the mosquito net has a significant protective effect on malaria. The survey selected 41 villages of the same natural environment as the malaria-endemic areas of the northern bank of the Gambia, with a total of 12,313. According to the random sampling of 1: 5, 600 children under 7 years of age were selected. The incidence of the disease was investigated by monthly follow-up. The body temperature of 37.5 ℃ was observed and the blood film was taken. By the end of the rainy season, doctors examined each group of children and collected blood for hematology, parasitology and serology, and investigated the use of mosquito nets
