What protocol is recommended if a pregnant mother is exposed to varicella?

The recommended protocol for a pregnant mother exposed to varicella is the administration of immune globulin within 96 hours of exposure. This is particularly important because varicella, or chickenpox, can lead to significant complications for both the mother and the developing fetus if contracted during pregnancy. The use of immune globulin can provide passive immunity and help reduce the risk of severe disease.

Administration of immune globulin is most effective when given shortly after exposure, ideally within a specific time frame, to help the mother’s immune system mitigate the effects of the virus and protect the fetus from potential complications such as congenital varicella syndrome.

Other options such as immediate induction of labor or waiting for symptoms do not address the immediate concern of the viral exposure effectively, and starting antiviral treatment at delivery does not provide the necessary immediate intervention after exposure. By focusing on passive immunization within the critical time frame, the correct approach helps safeguard both the pregnant mother and her developing baby.
