Abstract: Objective Objective To understand the changes of positive rates of IHA detections of outpatients in schistosomiasis clinic. Results Results The data of IHA detections of outpatients in schistosomiasis clinic in Hubei Provincial Center for Disease Control and Prevention were collected and analyzed statistically from 2005 to 2014. Results Results A total of 7 113 outpatients were detected by IHA test，and 547 of them were positives with a positive rate of 7.69%. The positive rate of IHA test was on an upward slope be? fore 2008，and the rate reached 14.85% in 2008，which was significantly higher than that in 2005（5.81%） （χ2 = 47.40，P＜ 0.01），then it was on a declined stage after 2008，and the positive rate decreased to 3.76 in 2014，which was significantly lower than that in 2008（χ2 = 12.29，P＜0.01） . The positive rate of outpatients in the 10～＜30 years age group was higher than those in other age groups（all P < 0.012 5），and the male positives were more than the female ones. Conclusions Conclusions The schisto? somiasis endemic situation has been significantly decreased in Hubei Province. The male and people in 10～＜30 age group are the high risk groups，so the targeted health education should be strengthened.
