Objective: To evaluate the end-term effectiveness of the medium-and-long-term programme for prevention and control of schistosomiasis in Fanchang County, Anhui Province.
Methods: The epidemiological data of schistosomiasis were collected and analyzed in Fanchang County from 2004 to 2014. The end-term effectiveness of the programme was observed and evaluated.
Results: From 2004 to 2014, 1 938 schistosomiasis patients and 64 256 persons with the history of infested water contact were treated. Totally 12 cattle-times of schistosome infected cattle and 2 745 cattle-times of cattle with the history of infested water contact were treated. The area with snails controlled by molluscicides was 7 758.1 hm2, and the area with snails controlled by environmental modification was 36.0 hm2. The integrated control measures were carried out in all of the endemic villages with human infection rate being higher than 1%. Up to 2014, the infection rates of human and cattle, and the incidence rate of acute schistosomiasis were reduced to 0.27%, 0 and 0, respectively; the area with snails reduced to 103.20 hm2; the densities of both living snails and infected snails showed a declining trend in general.
Conclusions: The effect of the integrated strategies of schistosomiasis control is remarkable, and the whole county reached the criteria of transmission-controlled of schistosomiasis.
