The idea that malaria in South-East Asia is synonymous with adult malaria is questioned in this paper. In the Lao People's Democratic Republic, community-based malariometric data were collected in Savannakhet Province, which shares borders with Viet Nam in the east and Thailand in the west. The data indicate that endemic malaria is rural and stable in large areas of the province. In these areas, which are rarely subject to malaria control, there is significant childhood malaria. A little more than one-quarter of individuals examined in mass blood surveys carried out in the peak malaria season were parasite-positive. Unlike other studies in the region reporting a declining risk of positive parasitaemia with age, thus suggesting immunity consistent with high and prolonged exposure to malaria, the communities studied in the Lao People's Democratic Republic did not show the expected acquisition of immunity. Further community-based studies on this matter are therefore warranted.
本文对东南亚疟疾等同于成人疟疾这一观点提出质疑。在老挝人民民主共和国，在与东部的越南和西部的泰国接壤的沙湾拿吉省收集了基于社区的疟疾测量数据。数据表明，该省大部分地区的地方性疟疾呈农村性且稳定。在这些很少进行疟疾控制的地区，儿童疟疾发病率很高。在疟疾高发季节进行的大规模血液调查中，略多于四分之一接受检查的人寄生虫呈阳性。与该地区其他研究报告的随着年龄增长寄生虫血症阳性风险下降，从而表明与长期大量接触疟疾相一致的免疫力不同，老挝人民民主共和国所研究的社区并未表现出预期的免疫力获得情况。因此，有必要就此问题开展更多基于社区的研究。
