Some experience minor symptoms. folks that are additional seemingly to experience signs and symptoms of CMV include:

• Newborns who became infected with CMV before they were born (congenital CMV).

• Infants who become infected during birth or shortly afterward (perinatal CMV). This group includes babies infected through breast milk.

• People who have weakened immune systems, such as those who have had an organ, bone marrow or stem cell transplant, or those who are infected with HIV.

Babies

Most babies who have innate CMV seem healthy at birth. range of|some|many} babies who have congenital CMV who appear healthy at birth develop signs over time — typically not for months or years after birth. The foremost common of those late-occurring signs are hearing disorder and organic process delay. A small number of babies can also develop vision problems.
