**7. Final considerations**

Cytomegalovirus is a common agent that can be seen all over the world. Although CMV is generally asymptomatic in healthy individuals, it can lead to severe infection in individuals with immune deficiency. During pregnancy, CMV also cause significant disabilities in babies whose mother has CMV. After its primary infection, the virus remains as an inactive form in the host throughout the life. Recurrent CMV infections may occur with the reactivation of the silent virus. Due to the fact that congenital CMV infections are asymptomatic, a hearing test is strongly recommended to the newborns.
