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 positive rate of serum IHA detection in schistosomiasis specialist outpatients. Methods The IHA test data of outpatients from 2005 to 2014 in Hubei Provincial Center for Disease Control and Prevention were collected and analyzed statistically. Results A total of 7 113 IHA patients were detected in this specialist outpatient department from 2005 to 2014, with 547 positive tests and a positive rate of 7. 69%. Before 2008, the positive rate was 14.85%. (5.81%) in 2005 (χ ~ 2 = 47.40, P <0.01). After 2008, the positive rate dropped to 3.76% in 2014, which was significantly lower than that in 2008 (χ ~ 2 = 12.29, P <0.01). The positive rate of IHA in 10 ~ <30 years old group was higher than that in other age groups (P <0.012 5). The number of male IHA and blood test positive was more than that of female. Conclusion The epidemic situation of schistosomiasis in Hubei Province decreased significantly. Male and 10 ~ <30 years old group were infected with high risk population. Health education measures should be carried out in a targeted manner.
