目的：掌握湖北省血吸虫病潜在流行区疫情动态。方法2008-2012年在湖北省选择三峡库区和汉江流域血吸虫病潜在流行区设立固定监测点和流动监测点，采用间接血凝试验（IHA）、Kato-Katz法或塑料杯顶管法调查当地居民、流动人口及家畜血吸虫感染情况。在可疑环境开展钉螺调查，并在三峡库区开展钉螺扩散调查。结果调查当地6～65岁居民6052人，IHA阳性72例，阳性率为1.19％，72例IHA阳性者Kato-Katz法检测均为阴性。检测流动人口5004人，IHA阳性68例，阳性率为1.36％，68例IHA阳性者Kato-Katz法检测均为阴性。钉螺调查287.07 hm2，未查获钉螺，钉螺扩散及可疑环境调查亦未发现钉螺。结论湖北省血吸虫病潜在流行区发现一定数量的IHA阳性者，应继续加强监测。

Objective To explore the potential key risk factors of schistosomiasis transmission in potential endemic areas so as to provide the evidence for setting up the prediction and surveillance systems of schistosomiasis outbreak epidemic. Methods From 2008 to 2012,fixed and mobile surveillance sites in potential endemic areas of 2 counties in Hubei Province were selected. The immunological assays and stool examinations were carried out to investigate the schistosome infection situation of local people, mobile population and livestock. The distribution of Oncomelania hupensis snails was investigated in risk areas and suspicious ar-eas,and spreading patterns of snails were observed in the rivers that directly connected with the Yangtze River. Results A total of 6 052 local people aged 6-65 years were screened by IHA immunological tests,and the positive rate of antibody was 1.19%(72/6 052). Totally 72 antibody positives were examined by Kato-Katz technique and there were no positives. A total of 5 004 mo-bile persons were tested by IHA immunological tests and the positive rate was 1.36%(68/5 004). Totally 68 antibody positives were examined by Kato-Katz technique and there were no positives. Totally 287.07 hm2 potential endemic areas were investigated for Oncomelania snail detection,and no snails were found. The investigation on snail spreading patterns and the surveillance on suspicious circumstances were carried out,with no snails found. Conclusions In the schistosomiasis potential endemic areas, some positives of IHA immunological tests are found. Therefore,monitoring is still needed to be strengthened.
