Abstract:

From 2005 to 2010, the infection rates of schistosomiasis among residents (above 6 years old) were 13.34%, 9.59%, 4.81%, 3.03%, 2.35% and 2.19%, respectively. The positive rates of schistosomiasis among domestic animals fluctuated from 2.50% to 25.92%. Oncomelania snails were not found inside embankment since 1980, yet a high density of infected snails was found at low and uneven areas outside embankment. The cattle were the main infectious source and we should strengthen the ad? ministration and control of cattle.
