Study on risk assessing indicator system after schistosomiasis transmission interruption in Wuxi City / 中国血吸虫病防治杂志

ABSTRACT

Objective To establish a risk assessing indicator system after the transmission interruption of schistosomiasis in Wuxi City,so as to provide evidences for formulating strategies on schistosomiasis control and prevention. Methods A primary risk assessing indicator system was established based on the literature review. Alternative indicators were scored and screened to establish a final indicator system through two rounds of Delphy method and the related normalized weights and combined weights were also calculated. Results The risk assessing indicator system was established through two rounds of expert consultation in-cluding 3 first grade indicators and 15 second grade indicators. Among the first grade indicators,the normalized weights of natu-ral environment,key populations and social environment were 0.3706,0.2929 and 0.3365,respectively. Among the second grade indicators,the migrant population accounted for the highest combined weight of 0.1252 compared to domestic animal of 0.0371. The authority degree among the first grade indicators was between 0.91 and 0.93,while the authority degree among the second grade indicators was between 0.79 and 0.92. Conclusion The scientific and authoritative risk assessing indicator sys-tem after the transmission interruption of schistosomiasis is established,which provides the evidences for risk assessment on schistosomiasis transmission in Wuxi City.
