由曼氏血吸虫感染引起的肠道血吸虫病在乌干达是一个普遍的公共卫生问题。虽然早就知道它是地方病，但目前在该国的分布情况需要更新寄生虫学数据，以帮助指导有计划的控制。我们报告1998年和2002年之间收集的数据，从201所学校和68个社区在乌干达。按照流行病学的预期，流行率和强度随着年龄的增长而增加，在10-20岁时达到高峰，此后随着年龄的增长而适度下降，而强度随着年龄的增长而下降得更快，学校的感染流行率与平均感染强度呈非线性关系。我们使用地理信息系统来绘制感染分布图，并将寄生虫学数据与内插的环境表面重叠。衍生的地图表明，感染的广泛发生和感染流行率的显着变化，与流行率通常最高的湖岸附近和沿着大河。在海拔1400米以上或年总降雨量
Intestinal schistosomiasis caused by infection with Schistosoma mansoni is a widespread public health problem in Uganda. Although long known to be endemic, its current distribution within the country requires updating of parasitological data to help guide planned control. We report such data collected between 1998 and 2002 from 201 schools and 68 communities across Uganda. In accordance with epidemiological expectation, prevalence and intensity increased with age, peaking at 10-20 years and thereafter declined moderately with age, whereas intensity declined more rapidly with age, and the prevalence of infection in a school was non-linearly related to the mean intensity of infection. We used geographical information systems to map the distribution of infection and to overlay parasitological data with interpolated environmental surfaces. The derived maps indicate both a widespread occurrence of infection and a marked variability in infection prevalence, with prevalence typically highest near the lakeshore and along large rivers. No transmission occurred at altitudes >1400 m or where total annual rainfall was
