Horizontal In Utero Acquisition of Cytomegalovirus Infection in a Twin Pregnancy

摘要

It is generally accepted that viral infections can be transmitted horizontally by direct or indirect contact with virus-excreting persons, and some viral infections can be transmitted vertically, either prenatally or perinatally, from mother to child. This report presents data strongly supporting a prenatal horizontal acquisition of human cytomegalovirus infection in a twin pregnancy.
