若依精神科医师诊疗过的病人来做推估,点盛行率(point prevalence)只有0.05%至1%. 也有的学者认为,...流行率(prevalence)是一个比例...点流行率(point prevalence):指特定的...时间点的流行率

prevalence：盛行率

(即使不是有没有超过消费上限那麼黑白分明,而要牵涉个人判断,那里的理论考虑仍不会建基於实践考虑的. )因为抗病毒药物的发展,盛行率(Prevalence)上升是必然的现像,盛行率上升必定引致感染率上升,这也是基本原则和演绎,不是诠释.

prevalence rate：患病率

(三)患病率(prevalence rate) 1.定义 患病率也称现患率.是指某特定时间内总人口中某病新旧病例所占比例.患病率可按观察时 间的不同分为期间患病率和时点患病率两种.时点患病率较常用.通常患病率时点在理论上是无长度的,
