ResumoObjective To understand schistosomiasis of mobile population in Shanghai,and provide information for the development of control strategies.Methods Thirty survey points(administration villages) were selected by cluster sampling from 5 districts in Shanghai,and the information about mobile population was collected.In every survey point,100 people,from 105 schistosomiasis endemic counties or 38 re-endemic counties,age from 6 years to 65 years,was involved in this study.Questionnaire survey and serum tested by indirect hemagglutination(IHA)were done for every individual,and fecal examination was done to the person with positive of IHA.Results About 3.82% mobile population came from schistosomiasis endemic counties or 38 re-endemic counties.A total of 2 992 mobile people were surveyed.Sixty-four persons were positive by IHA test(2.14%).Current occupation,type of endemic areas,treatment history,and respective province,were recognized as influence factor of the result of IHA test by binary logistic regression.It was estimated that there were about 4 233 mobile people with IHA positive in Shanghai.Compared to 2004,the number of serological positive cases dropped by 71.88%.Fecal samples of 54 IHA positive cases were collected and examined,but no schistosome egg was found.Conclusions The imported schistosomiasis cases was the major risk factor in the re-endemic of schistosomiasis in Shanghai.The workers from schistosomiasis endemic counties,engaged in agriculture or animal husbandry in Shanghai suburbs,were proposed as the key population for the selective initiative surveillance.
