A random sample bloodsmear survey was conducted during evening hours in Georgetown, Guyana, to determine the prevalence of Wuchereria bancrofti microfilariae. In all, 182 of 2,818 persons tested (6.5%) yielded positive results--indicating that the overall prevalence of Bancroftian filariasis has not diminished and may be on the rise. Relatively high prevalences found in children and adolescents point to active transmission. It appears likely that certain socioeconomic and environmental factors have been contributing to such transmission, and that similar factors could encourage increased transmission elsewhere in the Americas as well.
在圭亚那乔治敦的夜间时段进行了一项随机抽样血涂片调查，以确定班氏吴策线虫微丝蚴的流行情况。总共2818人接受检测，其中182人（6.5%）结果呈阳性，这表明班氏丝虫病的总体流行率并未下降，而且可能正在上升。在儿童和青少年中发现的相对较高的流行率表明存在活跃传播。某些社会经济和环境因素似乎一直在促成这种传播，而且类似因素也可能促使美洲其他地区的传播增加。
