Abstract:

Objective  To investigate the endemic status and trend of schistosomiasis from the national surveillance sites in Hubei province in 2014 in order to provide the scientific basis for planning comparable prevention and control strategies. Methods  According to the national surveillance protocol(Revision in 2011), we conducted surveys on the incidences of schistosomisis in population and livestock as well as the prevalence of Oncomelania snails and risk factors associated with the infection in the 16 national surveillance sites in Hubei province, and the results were analyzed with software SPSS version 19.0. Results   The infection rate for residents and cattle was 0.18% and 0, respectively. The mean density of living snails was 0.230/0.11 m2.  The occurrence rate of frames with living snails was 7.987%, and no infected snails were found. Conclusion  Although endemic schistosomiasis in human and livestock tends to decline in the national surveillance sites in Hubei province, yet the areas with living snails are still large, suggesting that this situation should be managed with great efforts in order to minimize the risks of resurgence.
