The cytomegalovirus (CMV) is a widespread and usually harmless virus. If you have it while pregnant, it can pose issues in your baby (congenital CMV). Congenital CMV infection affects around one out of every 200 babies, according to the Centers for Disease Control and Prevention. CMV infection in the neonate results in a reduced interferon response compared to infection in adults. During pregnancy, CMV infection and the risk of reactivation of cytomegalovirus infection have been described. Congenital CMV infection can also result from these.
