Abstract:

A risk assessment index system after schistosomiasis transmission interruption in Wuxi city was established by the Delphi method and transmission risk was assessed by the fuzzy comprehensive evaluation method. The risk assessment index system had primary indicators of natural environment, key populations and social environment, with normalized weights of 0.370 6, 0.292 9 and 0.336 5, respectively. Among the 15 secondary indicators secondary indicators, population from endemic areas of schistosomiasis had the highest combined weight of 0.125 2 while free-range livestock had the lowest combined weight of 0.037 1. The final analysis indicated a low level of schistosomiasis transmission risk after the interruption of transmission in Wuxi city, with a risk assessment score of 0.193 6.

Key words: Schistosomiasis, Transmission interruption, Risk assessment, Fuzzy comprehensive evaluation method
