[Investigation on schistosomiasis japonica infection and preventive knowledge of immigration population in Jinshan District, Shanghai].

OBJECTIVE: To investigate the schistosomiasis japonica infection and preventive knowledge of immigration population in Jinshan District, Shanghai so as to provide the evidence for improving the control work. METHODS: The immigration population from schistosomiasis endemic provinces and local people were screened by serum IHA screening for schistosome infection, and the positives were further examined by Kato-Katz technique and the miracidium hatching method. The schistosomiasis preventive knowledge and behaviors were investigated by questionnaires. RESULTS: A total of 579 were investigated with 348 immigration people and 231 local people, and among them, the male accounted for 72.0% and female accounted for 28.0%. In the immigration population, the main age group was 20-29 (56.0%), and 56.6% of the immigration had an education level at senior middle school or higher. The most proportion of immigration was from Anhui Province (36.2%). There were 4 IHA positive persons (1.15%) in the immigration, and 1 was positive in the stool test, and the schistosome infection rate was 0.29%. There were no positives in the local people. The schistosomiasis preventive knowledge of the immigration was generally poor, and some people' s behaviors of see doctor and medication were incorrect. CONCLUSION: There are schistosome infected persons among the immigration population from schistosomiasis endemic provinces, and their schistosomiasis prevention knowledge was poor, thus there is a schistosomiasis transmission risk.
