作者对圣露西恩(St.Lucian)一个2000人口的滨海农村进行了不同年龄组毛首鞭形线虫感染率和感染度的现场调查,共查了231人,收集其中119名感染者的出生年月资料,结合经甲苯达唑治疗前后的粪便虫卵计数(Kato法)以及开始服药后的第3天起连续收集4天的粪便成虫计数,进行观察探讨。结果显示感染率不能反映鞭虫感染的真象,所获曲线自1岁开始急剧上升到4～5岁,其后曲线呈平台型,各年龄组感染率无大差异。感染度则自1岁开始随年龄而升高,其高峰在5～14岁。1～10岁组儿童所淘获虫数占所有有儿童所淘虫数的84％,虫荷/人
The authors conducted a field survey of the prevalence and severity of larval nematodes in a 2000-population coastal rural area of St.Lucian in a total of 231 people and collected 119 of them Years of data, combined with the mebendazole treatment of mebendazole eggs before and after the count (Kato method) and began taking the first 3 days after administration of faecal colony collected continuously for 4 days count were observed and discussed. The results showed that the infection rate can not reflect the true image of whipworm infection, the curve from 1 year old rose sharply to 4 to 5 years old, followed by the curve was platform type, no significant difference in infection rates in all age groups. Infection from the age of 1 began to increase with age, the peak in the 5 to 14 years old. The number of children scavenged by children aged 1 to 10 accounted for 84% of the total number of children screened by the children,
