摘要: 在1987—1990年,对影响高原峡谷型血吸虫病流行区云南省巍山县中和村血吸虫病流行的自然、生物和社会因素作了流行病学调查,并应用层次分析法和概率累和法对调查资料进行了分析综合处理。结果表明,29个流行因素中,以年均气温、传染源数量、感染螺点数、水温、年均雨量等12个因素对血吸虫病流行的影响为大。干预试验前后的概率影响度值分别为3.513和2.066,下降了41%。

Abstract: In Zhonghe Village of Weishan County,Yunnan Province,a schistosomiasis endemic area of mountainous valley subtype,an epidemiological investigation was conducted on its natural,biological and social factors influencing schistosomiasis transmission in 1987 1990.The results were analyzed by stratified sampling analysis and probability accumulation method.It was demonstrated that 12 of 29 factors were the most important factors influencing schistosomiasis transmission including annual average air temperature,number of infection sources,number of spots with infected snails,water temperature and annual average rainfall,etc.The values of influence degree before and after intervention measures were 3.513 and 2.066 ,respectively,the decrease being 41%.
