The Full Form of CMV is‍ Cytomegalovirus.

Cytomegalovirus (pronounced sy-toe-MEG-a-low-vy-rus), or CMV, is a common virus that infects people of all ages. Over half of adults have been infected with CMV by age 40. Most people infected with CMV show no signs or symptoms. When a baby is born with cytomegalovirus (CMV) infection, it is called congenital CMV. About one out of every 200 babies is born with congenital CMV infection.  About one in five babies with congenital CMV infection will have long-term health problems.

• Cytomegalovirus (CMV) is a common virus for people of all ages; however, a healthy person’s immune system usually keeps the virus from causing illness.
• The COVID-19 pandemic is changing rapidly and continues to affect communities across the United States differently.  If you have questions about keeping your families safe and healthy during the coronavirus pandemic, please visit the CDC’s coronavirus website and the People with Disabilities web page.

In the United States, nearly one in three children are already infected with CMV by age five. Over half of adults have been infected with CMV by age 40. 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 with CMV infection have no symptoms and aren’t aware that they have been infected.
