Abstract: Objective To explore the relationship between schistosome serum test positive rate of residents and positive rate of Oncomelania snails in a national schistosomiasis surveillance site of Jiangling County. Methods According to the national schistosomiasis monitoring scheme，the data of surveillance including the schistosome serum test positive rates of residents and positive rates of Oncomelania snails from 2005 to 2011 were collected and analyzed statistically. Results From 2005 to 2011， the schistosome serum test positive rates of residents were 26.09%，11.84%，10.37%，10.09%，12.08%，9.61%，and 6.00%，re? spectively；the schistosome positive rates of Oncomelania snails were 0.36%，0.08%，0.15%，0.129%，0.067%，0.091%，and 0.045%，respectively. There was a significant positive correlation between them（r = 0.929，P < 0.01） . Conclusion There is a positive correlation between schistosome serum test positive rate of residents and positive rate of Oncomelania snails. Therefore， we should strengthen the snail control.
