摘　　要：目的了解全国(除港澳台外)人群鞭虫感染状况,为制定防治规划提供依据。方法按全国统一方案进行抽样调查,粪检采用改良加藤厚涂片法定量。结果内蒙、辽宁、吉林省未发现鞭虫感染者,其余省(市、区)感染率在0.01%～31.35%之间,人群平均感染率为4.63%。感染者平均克粪虫卵数(EPG)18.99,以轻度感染为主,占89.75%。鞭虫感染受经济状况、居住环境、饮用水源和生产类型等因素影响,感染率女性高于男性,5～15岁组高于其他年龄,少数民族居民高于汉族居民,渔民高于其他职业者(P<0.01)。结论鞭虫感染仍是我国应当关注的重要公共卫生问题,预防控制工作不可松懈。Objective To understand the current situation of Trichuris trichiura infection in Chinese population and to provide scientific basis for prevention and cure in China.

The Kato-Katz thick smear methods were used to determine T. trichiura eggs of fixed quantity and qualities. Results The population infective rates of T. trichiura ranged from 0.01% to 31.35%, the average infective rate was 4.63% in China and no T. trichiura infection was found in inner Mogolia, Liaoning and Jilin. The average number of eggs per gram （EPG） was 18.99, and the most cases were mild infection（89.75%）. The females infection rate of T. trichiura was slightly higher than the males, and the highest infection rate was in age group of 5-15, minority nationality infection rate was higher than the Han people and the highest infection rate was fishermen.
