1997年雨季期间，对苏丹东部难民营室内喷洒马拉硫磷对发病率和死亡率的影响进行了探索性试验。9月中旬，对随机选择的5个难民营的房屋内墙喷洒马拉硫磷，并将10月至12月难民营的发病率和死亡率与5个对照组的发病率和死亡率进行比较。除虫菊喷雾收集和人类着陆捕获分两轮进行。阿拉伯按蚊是最常见的嗜外嗜内种群。8个营地242只蚊的平均人血指数为0.51。1040只蚊子中只有两只携带孢子虫。采用聚合酶链反应法对83例疑似疟疾患者的血样进行寄生虫检测。喷洒后3个月内，喷洒营区的死亡率显著降低，但喷洒营区和未喷洒营区的临床疟疾发病率差异不显著。(C) 2001 Elsevier Science BN。版权所有。
An exploratory trial of the efficacy of indoor spraying with malathion on morbidity and mortality in refugee camps in eastern Sudan was conducted during the rainy season of 1997. The interior walls of houses from a randomly selected group of five camps were sprayed with malathion in mid-September and morbidity and mortality rates in the camps for the months October to December compared with rates in five controls. Pyrethrum spray collection and human landing catches were performed in two collection rounds. An exophagic but endophilic population of Anopheles arabiensis was the most common mosquito collected. The mean human blood index of 242 mosquitoes from eight camps was 0.51. Only two of 1040 mosquitoes examined harboured sporozoites. Blood samples of 83 putative malaria patients were examined for parasites by PCR. Mortality rates in the 3 months following spraying were significantly lower in sprayed camps although differences in clinical malaria incidence between sprayed and non-sprayed camps were not significant.
