肠寄生虫病是学生易患的常见病之一。长期以来,全国各地积极开展学校肠寄生虫病普查普治工作,取得了显著成效。近年来,随着生活水平的提高和卫生条件的不断改善以及开展学校健康教育,学校肠寄生虫病得到有效控制(尤其在城市),学生的蛔虫感染率比起80年代初已有明显下降。一些地区坚持每年二次给学生定期集体服药驱虫,连续十几年,使学生蛔虫感染率由41.61%下降至0.42%,效果明显。为此,在讨论当今学校肠寄生虫病控制对策时,一些专家提议:在全国范围内推行学生长期集体普服药物(称之预防性服药)和开展健康教育相结合的方法来最大限度控制肠寄虫病。中国学生营养促进会在制定“学生蛔虫感染计划防治方案”中也明确要求全国各地中小学校进行每年二次的集体驱虫。对此,笔者结合当地 Intestinal parasitic disease is one of the common diseases that students are susceptible to. For a long time, all over the country to actively carry out the general survey of intestinal parasitic diseases school work has achieved remarkable results. In recent years, intestinal infective diseases have been effectively controlled in schools (especially in cities) as living standards improve and sanitation conditions improve and school health education is implemented. Ascaris infection rates among students have dropped significantly from the early 1980s. In some areas, they insist on giving students twice a year a collective drug to repel worms for more than 10 consecutive years, reducing the infection rate of ascaris from 41.61% to 0.42%. The effect is obvious. To address this issue, in discussing control strategies for intestinal parasites in schools today, some experts have proposed that there should be a nationwide implementation of a combination of long-term, group-based generalized medication for students (called preventive medication) and health education to maximize control of the intestine Invasive disease. Chinese Students Nutrition Association in the development of “Student Ascaris infection program prevention and control programs” also explicitly require primary and secondary schools across the country twice a year collective deworming. In this regard, I combine the local
