背景:本文为供者逆转录病毒流行病学研究报告,通过比较单采和全血供者的人口统计学资料,未被发现的危险行为和病毒传染病的流行情况以及患病率,以了解这两个人群的特征及对在输血传播的病毒性传染病相对安全性方面作出评估。研究目的及方法:通过研究1991年至1994年间由美国5个州立血液采集中心收集的资料,共36119名单采供者(≥1次单采捐献)和138万名全血供者(≥1次全血捐献)。比较了他们的病毒性传染病的人口统计学资料,流行率(每10万供者)和发病率(每10万人年)。可能延迟献血的危险行为定义为,如果他们的那些危险行为被讲出来,有可导致供血延期。可能延期献血的危险行为
Background: This is a retrospective study on the epidemiology of donor retroviruses. By comparing the demographic data of both apheresis and whole blood donors, the prevalence of undiscovered dangerous behaviors and viral infections, and the prevalence to understand The characteristics of these two populations and their assessment of the relative safety of transmissible viral infections. OBJECTIVES AND METHODS: By studying data collected from five U.S. State Blood Collection Centers from 1991 to 1994, a total of 36,119 single-donor donors (≥1 single-donor donations) and 1.38 million whole blood donors (≥1 Whole blood donation). Demographic information on their viral infections was compared, prevalence (per 100,000 donors) and morbidity (per 100,000 person-years). Dangerous behaviors that may delay blood donation are defined as delaying the supply of blood if their dangerous behaviors are stated. May delay the dangerous behavior of blood donation
