Cytomegalovirus (CMV)


EARLY HEARING DETECTION AND INTERVENTION (EHDI) - CYTOMEGALOVIRUS (CMV)

Cytomegalovirus (pronounced sy-toe-MEG-a-low-vy-rus), or CMV, is a common virus that infects people of all ages. In the United States, nearly one in three children are already infected with CMV by age five. Over half of adults by age 40 have been infected with CMV. Once CMV is in a person's body, it stays there for life and can reactivate. A person can also be re-infected with a different strain (variety) of the virus.

 

Most people infected with CMV show no signs or symptoms. That's because a healthy person's immune system usually keeps the virus from causing illness. However, CMV infection can cause serious health problems for people with weakened immune systems and for unborn babies (congenital CMV).
