[Effect of schistosomiasis control in Jingzhou City from 2009 to 2013].

OBJECTIVE: To evaluate the effect of schistosomiasis control in Jingzhou City of Hubei Province from 2009 to 2013, so as to provide the reference for the establishment of control strategy in the future. METHODS: The annual reports on schistosomiasis control from 2009 to 2013 in nine counties (cities, districts) in Jingzhou City were collected and analyzed sta- tistically. RESULTS: The estimated number of schistosomiasis patients in Jingzhou City dropped from 78 903 in 2009 to 28 034 in 2013, with a reduction rate of 63.37%. The schistosome infection rate of residents dropped from 2.21% in 2009 to 0.65% in 2013, which showed an exponential decline trend (y = 3.196e(-0.317x)). The number of cattle with schistosomiasis decreased from 2 132 in 2009 to 0 in 2013, and the infection rate of cattle dropped from 1.87% in 2009 to 0% in 2013. Only 2 cases with acute infection of schistosome were found in 2009, and no schistosome infected snails were found out in 2 consecutive years, 2012 and 2013. CONCLUSIONS: The endemic level of schistosomiasis in Jingzhou City has decreased significantly. In order to consolidate the achievement of control, the comprehensive strategy including infection source control, snail control with mol- luscicides and snail surveillance should be implemented.
