Analysis of schistosomiasis endemic situation in Jiangling County from 2004 to 2013

OBJECTIVE: To analyze the schistosomiasis endemic situation and understand its transmission trend in Jiangling County from 2004 to 2013, so as to improving the schistosomiasis control. METHODS: The relevant data of schistosomiasis were collected and analyzed statistically in Jiangling county from 2004-2013. RESULTS: The human prevalence of schistosomiasis was decreased from 10.22% in 2004 to 0.63% in 2013 with the descend rate of 93.84%, and the notable descend rate was 76.92% from 2009-2013. The cattle infection rate was decreased yearly from 7.59% in 2004 to 0 in 2013. The appearance rate of frames with living Oncomelania hupensis snails and the infection rate of snails reduce by 17.53% and 100% respectively. CONCLUSIONS: After 10-year control, the endemic situation of schistosomiasis in Jiangling County decreases and is at a low level. However, the risk factors of transmission still exist. Therefore, the comprehensive control measures still should be enhanced continuously.
