Abstract:

【Abstract】 Objective  To analyze the epidemiological characteristics of schistosomiasis in Eryuan County of Yunan province for policy decisions in consolidating the achievement. Methods  The informative data on schistosomiasis prevention and control from 2004 through 2013 were collected, and retrospectively analyzed and compared with historical records. Results  Eryuan County used to be schistosomiasis severely hit area. After 60 years of effort, the schistosomiasis endemic tended to fall year by year, and current rates of population infection and the domestic cattle infection were greatly reduced by 96.62% and 98.84%, respectively against 2004. In the past years, no single acute schistosomiasis case was reported. Areas with snail existence were reduced by 70.05% in 2013 as compared with those in 2004, and 26 villages were up to the criteria of schistosomiasis transmission interruption in 2014. Conclusion  Although the achievement is remarkable in Eryuan County in schistosomiasis prevention and control, yet some difficulties and problems are still existing, which suggests that there is long way to go to maintain the accomplishment.
