目的 对清远市市区托幼机构儿童的蛲虫感染情况进行调查分析,为今后的防治工作提供依据和经验。方法 按自愿受检的原则对清远市市区在册托幼机构的儿童采用透明胶纸肛拭查卵法进行检查。结果 2007-2009年共检24 567人次,感染1 738人次,总感染率为7.07%,2007年、2008年、2009年的感染率分别为5.63%、6.96%和9.15%;2、3、4、5、6岁5个年龄组的感染率依次为2.45%、4.28%、6.47%、8.63%和8.36%;男性感染率为7.67%,女性感染率为6.25%;大、中、小规模托幼机构儿童的蛲虫感染率分别为6.16%、6.61%和11.50%;市中心区、市郊及城中村托幼机构儿童蛲虫的感染率分别为3.61%和12.64%。以上不同类别结果比较差异均有统计学意义(P<0.001)。结论 清远市市区托幼机构儿童蛲虫感染率呈逐年上升趋势,病例分布不平衡,今后要采取综合防治措施,降低蛲虫感染率。
Objective To investigate the prevalence of pinworm infection in children in kindergartens and nurses in urban areas of Qingyuan City, and to provide basis and experience for future prevention and treatment work. Methods According to the principle of voluntary inspection, the children in registered nurseries of urban areas of Qingyuan City were examined by the translucent adhesive tape anal swab method. Results A total of 24 567 people were infected with 1 738 infections in 2007-2009, with a total infection rate of 7.07%. The infection rates in 2007, 2008 and 2009 were 5.63%, 6.96% and 9.15% respectively; The infection rates of 5 and 5 age groups were 2.45%, 4.28%, 6.47%, 8.63% and 8.36% respectively. The infection rate was 7.67% in males and 6.25% in females. The rates of infection in large, medium and small scales The prevalence rates of pinworm in young children were 6.16%, 6.61% and 11.50% respectively. The prevalence rates of children were 3.61% and 12.64% respectively in the nurseries in urban centers, suburbs and urban villages. The differences between the above categories were statistically significant (P <0.001). Conclusion The prevalence of pinworm infection in kindergartens and nurseries in urban areas of Qingyuan City has been increasing year by year with unbalanced distribution of cases. In the future, comprehensive prevention and control measures should be taken to reduce the incidence of pinworm infections.
