Birth-acquired herpes
Definition:
Birth-acquired herpes is an infection with the herpes virus that an infant gets at the time of birth. Alternative Names:
HSV; Congenital herpes; Herpes - congenital Text Continues Below
Causes, incidence, and risk factors:
Newborn infants can become infected with herpes virus while in the uterus (intrauterine herpes), during passage through the birth canal (birth-acquired herpes, the most common method of infection), or in the period immediately following birth (postpartum). If the mother has an active genital herpes infection at the time of delivery, the infant is more likely to become infected during the birthing process. It is possible for a mother with a primary (first-time) herpes infection to transmit the virus to a child during birth. In addition, some people have had herpes infections in the past, but have not been diagnosed or treated. These people, not knowing that they have it themselves, may pass herpes on to their child. Herpes type 2 (genital herpes) is the most common cause of herpes infection in newborn babies, but herpes type 1 can also occur. Intrauterine herpes is very rare. It can cause severe brain damage, eye disease, such as inflammation of the retina (chorioretinitis), and skin lesions. Birth-acquired herpes can produce localized or systemic (throughout the body) disease. Infants may develop only a localized skin infection consisting of small fluid-filled blisters (vesicles) that rupture, crust over, and finally heal, often leaving a mild scar. A second type of birth-acquired herpes infection leads to encephalitis, an inflammation of the brain that can result in seizures and later neurologic (brain and nervous system) problems. If untreated, it may lead to death.
