Surveys for human malaria infections were conducted in the Lower Rufiji Basin in Tanzania, before and after the long rains in 1981. A multipurpose water resources development project has been planned in the area. Overall asexual malaria parasite, gametocyte and spleen rates of 38.6%, 3.8% and 21.1% respectively were observed before the long rains whilst respective parameters after the long rains were 44.5%, 2.8% and 17.3%. Malaria parasite species percentages of 95.5, 1.0, 0.2 and 3.4 were observed in respect of P. falciparum, P. malariae, P. ovale and mixed infections respectively for both periods. Malaria endemicity in the Lower Rufiji Basin ranges between mesoendemic to hyperendemic. Following implementation of the project, malaria is likely to become holoendemic.
1981年坦桑尼亚鲁菲吉河下游盆地在大雨前后开展了人体疟疾感染调查。该地区已规划了一个多用途水资源开发项目。大雨前观察到总的无性疟原虫、配子体和脾脏感染率分别为38.6%、3.8%和21.1%,而大雨后的相应参数分别为44.5%、2.8%和17.3%。两个时期恶性疟原虫、三日疟原虫、卵形疟原虫及混合感染的疟原虫种类百分比分别为95.5%、1.0%、0.2%和3.4%。鲁菲吉河下游盆地的疟疾流行程度从中度流行到高度流行不等。项目实施后,疟疾可能会成为全流行。
