Despite increasing institutional and financial support, certain public health issues are still neglected by the Chinese Government. The present paper examines the soil-transmitted helminth (STH) infection and reinfection rates by conducting a survey on 1724 children in Guizhou Province, China. Our results indicate that 37.5 percent of children had been infected with one or more of the three types of tested STH. However, only 50.4 percent of children reported having taken deworming medicine during the 18-month period before the survey. Of those who reported being dewormed, 34.6 percent tested positive for STH infections. Poverty and number of siblings are significantly and positively correlated with infection and reinfection, and parental education is significantly and negatively correlated with infection and reinfection. Given the ineffectiveness of treatment in these areas to date, for anthelminthic campaigns to actually succeed, China must pay more attention to local- level incentives to improve children's health. 相似文献

一、定期驱虫,消除感染源1.预防性驱虫。每年4~5月和10~1 1月各驱虫一次,对寄生虫感染流行严重的地方,要每季度驱虫一次,尤其在夏季,每2个月须驱虫一次。此外,在春季天气暖和时进行一次药浴,可有效防止羊螨病等体外寄生虫病的发生。2.治疗性驱虫。根据对山羊粪便的检查或对死羊的解剖,依感染轻重对症驱虫。药物驱虫1周后,应再驱虫1 相似文献
