The Centers for Disease Control and Prevention maintains a national surveillance system that provides data about the HIV/AIDS epidemic for program planning and resource allocation. Until recently, incidence of HIV infection (i.e., the number of individuals recently infected with HIV) has not been directly measured. New serologic testing methods make it possible to distinguish between recent and long-standing HIV-1 infection on a population level. This article describes the new National HIV Incidence Surveillance System.
疾病控制与预防中心维持着一个全国监测系统,该系统可为项目规划和资源分配提供有关艾滋病毒/艾滋病疫情的数据。直到最近,艾滋病毒感染率(即最近感染艾滋病毒的个体数量)一直没有得到直接测量。新的血清学检测方法使得在人群层面区分近期和长期的HIV-1感染成为可能。本文介绍了新的全国艾滋病毒感染率监测系统。
