With the development of sensitive screening assays to more adequately prote
ct blood supply, perinatal (mother-to-infant) transmissions of the virus ha
s become the most commonly reported HIV transmission risk for children. The
shift in transmission risk means that the immature immune systems and deve

ion. Perinatal HIV infection has unique features that are not commonly repo
rted in adult hosts. This article reviews the organ-specific manifestations
of perinatally acquired HIV infection.
