不久前de Vlas SJ等探讨了粪检法导致低估曼氏血吸虫感染率程度的问题。现在,他又与Van Oortmarssen G等一起通过虫卵计数的随机统计模型设计出一种利用单次粪检就能推导出“真实”感染率的估算图。 曼氏血吸虫虫卵计数模型基于两个不同的变量:一是由于个体间感染的虫数(或对
Not long ago de Vlas SJ et al explored the problem of stool tests leading to an underestimation of the rate of S. mansoni infection. Now, together with Van Oortmarssen G et al., He designed an estimate of the “true” infection rate using a single stool test using a stochastic statistical model of egg counts. The Schistosoma mansoni egg counting model is based on two different variables: one is due to the number of insects infected between individuals (or pairs
