Abstract:

【Abstract】 Objective  To understand the endemic status of schistosomiasis in surveillance sites in Wuhan in 2014 for scientific evidences to plan measures with prevention and control of this disease. Methods   Twenty-eight surveillance sites were established on administrative villages basis. Infections in residents and cattle as well as snail prevalence were monitored in each site, and related factors were examined.  Results  A total of 15 310 people and 348 cattle were examined in 2014, and 1 370.90hm2 of areas in 67 sites with or suspected with snails were surveyed. The results indicated that the infection rate was 0.05% for people and zero for cattle. The infection rate was decreased by 61.54% compared with that in 2013(χ2= 5.844, P=0.016). No infected snails were found in both inside and outside embankment areas. Conclusion  The schistosomiasis appears to be effectively controlled in the national surveillance sites in Wuhan City, however, surveillance should be continued in order to prevent the rebound of schistosomiasis through control of the infection sources.
