In some areas of Africa, health facility data have indicated declines in malaria that might have resulted from increasingly effective control programs. Most such reports have been from countries where malaria transmission is highly seasonal or of modest intensity. In Malawi, perennial malaria transmission is intense, and malaria control measures have been scaled up during the past decade. We examined health facility data for children seen as outpatients and parasitemia-positive children hospitalized with cerebral malaria in a large national hospital. The proportion of Plasmodium falciparum-positive slides among febrile children at the hospital declined early in the decade, but no further reductions were observed after 2005. The number of admissions for cerebral malaria did not differ significantly by year. Continued surveillance for malaria is needed to evaluate the effects of the increased malaria control efforts.
在非洲的一些地区，医疗机构的数据显示疟疾发病率有所下降，这可能是因为控制项目越来越有效。这些报告大多来自疟疾传播具有明显季节性或中度强度的国家。在马拉维，疟疾常年传播强度很大，过去十年中，疟疾控制措施已经扩大。我们研究了一家大型国家医院的门诊儿童和患有脑型疟疾的寄生虫血症阳性住院儿童的医疗机构数据。该医院发热儿童中疟原虫阳性载玻片的比例在十年早期下降，但 2005 年后未观察到进一步下降。因脑型疟疾住院的人数各年之间无显著差异。需要继续进行疟疾监测，以评估增加疟疾控制工作的效果。
