Child bearing age women constitute the fastest growing subset of the human immunodeficiency virus (HIV) infected population. Consistent with this fact is the increasing number of HIV infected children. Vertical transmission from mother to child is the most common route of infection. Because of the nature of the virus, it is difficult to determine the timing of infection. There are three time periods during which infection can occur: prenatally, perinatally, or postnatally. Evidence for each is presented within this review.
育龄妇女是感染人类免疫缺陷病毒（HIV）人群中增长最快的亚群体。与此事实相符的是，感染HIV的儿童数量也在不断增加。母婴垂直传播是最常见的感染途径。由于该病毒的特性，很难确定感染时间。感染可能发生在三个时间段：产前、围产期或产后。本综述将介绍每个时间段的相关证据。
