We analyzed point-prevalence data from 35 recent studies of human populations in which Plasmodium falciparum and one other Plasmodium species were the reported causes of malaria infections. For the P. falciparum-Plasmodium vivax pair, higher overall prevalence in a human population is associated with fewer mixed-species infections than expected on the basis of the product of individual species prevalences. This is not true for P. falciparum-Plasmodium malariae.
我们分析了最近35项关于人群的研究中的现患率数据,这些研究报告称恶性疟原虫和另一种疟原虫是疟疾感染的病因。对于恶性疟原虫-间日疟原虫这一组合,人群中总体患病率较高时,混合物种感染的数量比根据单个物种患病率的乘积预期的要少。而对于恶性疟原虫-三日疟原虫组合,情况并非如此。
