Objective To understand the current situation of schistosomiasis in Dali Prefecture, Yunnan Province in 2010, and to evaluate its effect of prevention and treatment, so as to provide reference for future prevention and treatment. Methods Development of “Dali Prefecture schistosomiasis monitoring program”, carried out as required epidemiological surveillance. Results A total of 7 epidemic surveillance spots were identified in the whole state, which were distributed in 5 endemic counties (cities) with schistosomiasis prevalence. The infection rate of residents in monitoring sites was 0.68%, the average infection rate of livestock was 0.49%, the area of snails was 176044m ~ 2, 0.177 3 /0.11m ~ 2), found no contagious snails. Conclusion The overall epidemic situation of schistosomiasis in Dali Prefecture in 2010 is still at a relatively low level.
