To evaluate the schistosomiasis control effect of county promotion and comprehensive control interventions in Jingzhou City.

The data of schistosomiasis endemic situation of 9 counties (cities, districts) in Jingzhou City from 2006 to 2010 were collected by a retrospective survey method, and the schistosome infection situation of residents and cattle were selectively examined in November, 2010.

The endemic situation in Jingzhou City from 2006 to 2010 presented a decline tendency. Compared to the infection rate of residents in 2006 (5.15%), that in 2010(2.22%) decreased by 56.89%, and no acute schistosomiasis cases were found. No sudden epidemic happened in the consecutive 5 years. The infection rate of cattle dropped from 8.04% in 2006 to 1.87% in 2010, with a reduction rate of 81.72%. The snail area and area with infected snails in 2010 were 31 070.61 hm2 and 321.70 hm2, respectively, with reduction rates of 3.68% and 71.20%, respectively, compared to those in 2006. Compared to 2006, the snail density and infection rate of snails in 2010 decreased by 63.76% and 64.74%, respectively.

After the implementation of the project with county promotion and comprehensive control interventions in Jingzhou City, the schistosomiasis control work has obtained obvious achievement, and the endemic situation has been controlled effectively.
