A cross-institutional research group has revealed for the first time in the world that infants with symptomatic congenital cytomegalovirus (CMV) infection who were treated with a combination of immunoglobulin fetal therapy and neonatal therapy with antiviral drugs were less likely to experience the severe aftereffects associated with the infection than those who only received the neonatal therapy. It is hoped that the number of children suffering severe aftereffects resulting from congenital CMV infection will decrease in the future. The research group included the following members: Doctor YAMADA Hideto (Director of the Center for Recurrent Pregnancy Loss and Genome Medical Center, Teine Keijinkai Hospital, visiting professor at Osaka University and former professor of the Department of Obstetrics and Gynecology, Kobe University Graduate School of Medicine)
