Methods The immigration popula? tion 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 preven? tive 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%.
