2005-2014年血吸虫病门诊就诊者IHA检测结果分析

IHA detection results of outpatients in schistosomiasis clinic,2005-2014

目的了解血吸虫病专科门诊就诊者血清IHA检测阳性率变化。方法收集2005-2014年湖北省疾病预防控制中心门诊就诊者IHA检测资料,并进行统计分析。结果2005-2014年,该专科门诊共采用IHA检测7 113人,547人检测结果为阳性,阳性率为7.69%;2008年以前为阳性率增高阶段,2008年血检阳性率达14.85%,较2005年（5.81%）明显升高（χ~2=47.40,P〈0.01）;2008年后为回落阶段,至2014年阳性率降至3.76%,较2008年显著下降（χ~2=12.29,P〈0.01）。10~〈30岁年龄组IHA阳性率高于其他年龄组,差异有统计学意义（P均〈0.012 5）;男性就诊及血检阳性人数均多于女性。结论湖北省血吸虫病疫情显著下降,男性和10~〈30岁年龄组为感染高危人群,应有针对性地开展健康教育措施。

Objective To understand the changes of positive rates of IHA detections of outpatients in schistosomiasis clinic. 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 A total of 7 113 outpatients were detected by 1HA 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 before 2008, and the rate reached 14.85% in 2008, which was significantly higher than that in 2005 （5.81%） （ x^2 = 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 （ x^2 = 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 The schistosomiasis 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.
