ABSTRACT
Objective To understand the epidemiologic trend and characteristics of the distribution of schistosomiasis in Yunnan Province, China. Methods The data of two sampling surveys on schistosomiasis in Yunnan in 1995 and 2003 were collected, and the database of GIS was set up. The spatial status of rates of human infection and cattle infection were analyzed by using the GIS software, ArcView 3.2, contours method. The relationships between rates of human infection and cattle infection in 1995 and 2003 were analyzed with SPSS statistical software. Results The high-risk areas of schistosomiasis in Yunnan were Dali City, Yongsheng, Heqing, Eryuan, Weishan and Nanjian counties, and those areas contained different infection grades which were intertwine. The rate of human infection was descendent and the distribution of high-risk areas of schistosomiasis was decreasing. The infection rate of cattle was higher than before in the south of epidemic areas in Yunnan. Those epidemic areas of schistosomiasis could be identified as three spatial distributions. Conclusions The control and prevention of schistosomiasis in Yunnan should be focus on Dali City, Eryuan, Weishan, Yongsheng, Heqing and Nanjian counties, and the key is synchronistical chemotherapy in human and cattle.
