ABSTRACT

OBJECTIVE: To understand the epidemic situation of schistosomiasis in Jiujiang City, so as to provide the evidence for formulating further control strategy. METHODS: The data of schistosomiasis control were collected in Jiujiang City from 2008 to 2014. and the indicators including the annual schistosome infections of human and cattle, acute schistosome infection, outbreak of schistosomiasis endemic, schistosome infected Oncomelania hupensis snails were analyzed statistically. RESULTS: Compared with 2008, in 2014, the infection rates of schistosomiasis declined by 98.40% and 92.54% in human and cattle respectively. The area of schistosome infected snails decreased from 103.24 hm² to zero. The occurrence rate of frames with snails and density of living snails declined from 14.86% and 0.334 5/0.1 m² to 6.89% and 0.126 5/0.1 m², respectively. The acute schistosomiasis infection cases occurred except 2011 and 2014. CONCLUSION: The control strategy emphasizing on infection sources control is effective in Jiujiang City, but the risk of schistosomiasis still exists, and the risk control and schistosomiasis control strategy should be strengthened.
