Abstract:
Objective To understand the distribution and characteristics of historical Oncomelania hupensis snail environ-ments and wetland environments in Wuxi City since 1952 so as to provide the evidence for formulating the monitoring strategy after the schistosomiasis transmission was interrupted. Methods A cross-sectional survey was conducted to collect the informa-tion of historical O. hupensis snail environments and wetland environments. Google Earth was used to present and analyze the distribution and characteristics of them. Results There were 2 124 historical O. hupensis snail environments in Wuxi City and the accumulative area was 2 995.7 hm2. In 2013 there were 61 surveillance sites of wetland with the area of 32.8 hm2 totally 1 695 snails were caught and no O. hupensis snails were found. Conclusion The historical O. hupensis snail environments were distributed widely and covered a large area in Wuxi City. The surveillance should be focused on the key environments and wetland.
