1998～2007年马鞍山市小学生血吸虫抗体检测报告

Analysis of Pupils' Serum Schistosoma Antibody Test Data from 1998 to 2007 in Ma'anshan

目的分析马鞍山市辖区小学生血吸虫抗体1998～2007年的动态变化,为评价防治效果和制定防治策略提供依据。方法采用IHA法,检测血清血吸虫抗体。结果10年来共检测3类、5类流行区小学生17 256人次,血检阳性率平均为1.65%。其中3类流行区学校学生血检阳性率为2.80%(183/6 559),5类流行区学校为0.94%(101/10 697);男生血检阳性率为2.23%(204/9 138),女生为0.99%(80/8 038);中、高年级学生血检阳性率为1.98%(239/12 061),低年级为0.87%(45/5 195)。前者血检阳性率均显著高于后者(P<0.01)。结论10年来,马鞍山市辖区小学生血检阳性率呈先上升后下降趋势,感染血吸虫状况总体上相对较轻,其中3类流行区学校、男生及中高年级学生感染血吸虫状况相对较重,是我们今后防治的重点对象。

Objective To analyze the pupils＇ serum anti - body to schistosoma from 1998 to 2007 in Ma＇ anshan so as to provide scientific evidence for evaluating the control results and exploring the control strategy. Methods Indirect hemag- glutination （IHA） test examination was used to screen the pupils. Results A total of 17 256 pupils were tested with IHA during a period from 1998 to 2007 , and the average serum positive rate was 1.65%. It was 2.80% （ 183/6 559 ） in the endemic school with 3 level, and 0.94% （ 101/10 697 ） in 5 level respectively. It was 2.23% （204/9 138 ） in boys, and 0. 99% （ 80/8 038 ） in girls respectively. It was 2.0% （ 239/12 061 ） in middle - high grade pupils, and 0.87% （ 45/5 195 ） in low grade respectively. By all, the former serum positive rate were significantly higher than the latter （ P 〈0.01 ）. Conclusion In the 10 years, it rose in the first years in terms of the serum positive rate, and declined in the latter years, which reached its peak in 2004. It was light infection status on the whole. And the endemic school with 3 level than 5 level, boys than girls, middle - higher grades than in low grade, the serum positive rate was higher. It suggested that the former infected more serious than the latter.
