目的了解和掌握小学生蛲虫感染情况,为制定综合防治决策提供依据。方法将龙川县划分为东南西北中5个片区,每个片区抽取1个乡镇,每个镇随机抽取1所小学,每所小学抽取200名学生,采用透明胶纸肛拭法检测蛲虫卵,并对其结果用流行病学统计方法进行统计分析。结果 5所小学调查总人数1 078人,感染人数280人,总感染率为25.97%,感染率最高的镇为30.93%,最低为14.09%;男女性别比为1:1.05,男女性别感染率差异无统计学意义(x2=0.2360,P>0.05);感染率较高的为6～10岁年龄组段,(平均感染率达29.21%)11～12岁年龄组段感染率较低(平均感染率只有13.51%)2个年龄组段感染率差异有统计学意义(x2=22.0380,P<0.01)。结论龙川县小学生蛲虫感染率仍较高,明显高于2009年广东省的蛲虫平均感染率(15.6%)水平,综合防治势在必行,应积极开展相关工作,把小学生蛲虫感染率降到最低水平。
Objective To understand and master the infection of pinworm in primary school and provide the basis for formulating comprehensive prevention and control policy. Methods Longchuan County was divided into five regions in the southeast, northwest and northwest of China. One township was selected for each region. One primary school was randomly selected in each town. 200 pupils were selected in each primary school. And the results of epidemiological statistical methods for statistical analysis. Results The total number of 5 primary schools surveyed was 1,078, with a total number of 280 people. The total infection rate was 25.97%. The highest infection rate was 30.93% in the town, the lowest was 14.09%. The sex ratio was 1: 1.05. (X2 = 0.2360, P> 0.05). The higher infection rate was in the 6-10 age group (mean infection rate was 29.21%), and the infection rate was lower in the 11-12 age group The rate of infection was only 13.51%) in the two age groups (x2 = 22.0380, P <0.01). Conclusion The prevalence of pinworm in primary school students in Longchuan County is still relatively high, which is obviously higher than the average infection rate (15.6%) of pinworm in Guangdong in 2009. Comprehensive prevention and control is imperative, and relevant work should be actively carried out. Rate down to the lowest level.
