Endemic situation of schistosomiasis in Qingxin county, Guangdong from 2006 to 2010

Objective To understand the endemic situation of schistosomiasis in Qingxin county, Guangdong province from 2006 to 2010. Method According to the schistosomiasis surveillance protocols of Guangdong province, synchronous surveillances of Oncomelania hupensis and infection sources in the former endemic areas were carried out in the Qingxin county, and the surveillance data were analyzed. Results From 2006 to 2010, an area of 13 hm2 in Qingxin county was surveyed and no living Oncomelania hupensis was found. 12 patients with a history of previous schistosomiasis were re-examined, and no chronic or advanced-stage infection was found. 10 out of 1 122 young people living in the endemic areas were sero-positive in the DIGFA test and no schistosomiasis patient was found. 2 456 subjects from the migrating population were also examined using the DIGFA test, 80 subjects were found to be sero-positive. Among these 2 456 subjects, 13 chronic schistosomiasis patients were found, and schistosome eggs were found in the stools from 2 patients. 38 imported cases were reported through the passive surveillance system from 2006 to 2010. Furthermore,1 900 cattle were surveyed by stool examination, and none of cattle was infected by Schistosoma japonicum. Conclusions Schistosomiasis is successfully controlled in Qingxin county. The surveillance program should be continued, especially the monitoring of the imported infection sources and Oncomelania hupensis.
