Abstract: Objective　To investigate the correlation between the source of Schistosoma japonicum infections and sociological factors among mobile populations in Haining City, so as to provide insights into the management of schistosomiasis among mobile populations in Haining City. Methods　A total of 12 villages were randomly sampled from 8 townships and 4 subdistricts in Haining City. The mobile populations from schistosomiasis?endemic areas were detected for S. japonicum infections using serological tests. In addition, the awareness of schistosomiasis prevention and control knowledge was investigated using a questionnaire survey. Results　A total of 1 019 mobile populations were investigated in 12 villages from Haining City, and 23 sero?positives were found, with a positive rate of 2.26%; however, no egg?positives were detected. Logistic regression analysis showed that the mobile populations with original occupations of aquaculture and husbandry were more likely to be sero?positive. The mobile populations had an overall low awareness rate of schistosomiasis prevention and control knowledge, and a higher rate was seen in sero?positive than in sero?negatives. Conclusions　The mobile populations with original occupations of aquaculture and husbandry were the key for the surveillance of source of S. japonicum infections. The health education should be intensified to improve the awareness of schistosomiasis prevention and control knowledge among mobile populations.

摘要： 目的　了解海宁市流动人群潜在血吸虫病传染源与社会因素的关系，为海宁市流动人口血吸虫病防控提供依据。方法 　2016年在海宁市8个乡（镇）、4个街道各随机抽取1个村（共12个村），对来自血吸虫病流行省份的流动人口进行血吸虫病血清学检查；并发放问卷，调查人群血吸虫病防治知识知晓率。结果　海宁市12个村共调查流动人口1 019人，检出血清学阳性23人，血检阳性率为2.26%，病原学检查未发现血吸虫病患者；logistic回归分析显示，流动人口中原职业为从事水产养殖、农牧业的人群更易检出血清学阳性；流动人口对血吸虫病防治知识的整体知晓率较低，血检阳性者血吸虫病防治知识知晓率高于血检阴性者。结论　原职业为从事水产养殖、农牧业的人群是海宁市流动人口血吸虫病传染源监测的重点，应加强宣传，以提高血吸虫病防治知识知晓率。
