[Analysis of schistosomiasis epidemic situation in Xinjiangkou Township, Sonzi City, from 2004 to 2013].

OBJECTIVE: To master the status of schistosomiasis transmission in Xinjiangkou Township, Sonzi City, from 2004 to 2013. METHODS: The data of schistosomiasis epidemic situation were collected and analyzed statistically in Xinjiangkou Township, Sonzi City, from 2004 to 2013. RESULTS: From 2004 to 2013, the areas with Oncomelania hupensis snails were 193.2-185.3 hm2, and the highest density of infected living snails was 0.00070 snail/0.1 m2 in 2007. However, after 2011, no infected living snails were found. The positive rate of blood tests was 9.46% and schistosomiasis infection rate was 7.36% in 2005, and the positive rate of blood tests was 3.27% and schistosomiasis infection rate was 0.57% in 2013. There were 7 cases of acute schistosomiasis in 2004 and 2005, respectively, and there were no acute schistosomiasis patients after 2006. The schistosome infection rate of cattle was 18.27% in 2004, and after 2007, the infection rate decreased below 5%. In 2013, all the cattle were obsoleted. CONCLUSION: The schistosomiasis transmission has reduced to a low level in Xinjiangkou Township. However, to realize the aim of schistosomiasis transmission controlled, the comprehensive control measures mainly based on infectious source control should still be strengthened.
