Abstract:
Objective To explore the impact of environment factors and social economic factors(environment interference factors for short)and control measures on the endemic status of schistosomiasis in Poyang Lake Eco?economic Region. Meth?ods The grey relational analysis model was applied to analyze the relationships between the key indexes of schistosomiasis epi?demic status and the environment interference factors and control measures in Jiujiang City of Poyang Lake Eco?economic Re?gion. Results Six environment factors,which included the annual average water level of Poyang Lake,average annual tempera?ture,storm frequency,annual average relative humidity,annual sunshine duration,and annual precipitation,had the most closed relationship with the indexes of schistosomiasis epidemic status(all ri>0.9). Among the socioeconomic factors,the num?ber of health technicians and beds of health facilities were most associated with the indexes of schistosomiasis epidemic status. Among the control measures of schistosomiasis,the number of cattle treated with extending chemotherapy,chemically killing of Oncomelania hupensis snails and eco?renovation were most associated with the indexes of schistosomiasis epidemic status. Con?clusion The various environment interference factors and their interaction should be considered in formulating the comprehen?sive control strategy for schistosomiasis,and the control strategy should be adjusted according to the epidemic dynamic and schistosomiasis?focused targets,so as to further strengthen the scientificity and validity of the control strategy.
