肠道线虫感染的发病率和传播动力学主要取决于虫荷量,确定决定虫荷量的决定因素,对发病情况和控制感染,有极重要的意义。现有的理论认为,感染程度取决于对感染的暴露率与宿主抗力所致的感染损耗率之间的平衡。本文目的确定流行区感染性土源性蠕虫虫卵的摄入率,并对以这种方法估算的暴露率与感染率进行了比较。对象为牙买加首都金斯顿的2个儿童养育院的蛔虫和鞭虫感染者。养育院甲有27名,平均年龄7.2岁,养育院乙有24名,平均年龄3.1岁。在甲苯达唑治疗的0,1,2和3个月,测定粪便内不
The incidence of gut nematode infection and its dynamics of transmission depend mainly on the amount of insect burden. Determining the determinants of insect burden is of great importance for the incidence and control of infection. The existing theory holds that the degree of infection depends on the balance between the rate of exposure to infection and the rate of infection lost due to host resistance. The purpose of this paper is to determine the incidence of infective soil-borne worm eggs in endemic areas and to compare exposure rates estimated by this method with infection rates. The object is roundworm and whipworm infected persons in two child-care centers in Kingston, Jamaica. There are 27 nursing homes, with an average age of 7.2 years and a nursing home of 24 with an average age of 3.1 years. At 0, 1, 2, and 3 months after mebendazole treatment, no stools were measured
