Cytomegalovirus, or CMVirus, is a common virus that affects people of all ages, races, ethnicities and geographies. It’s typically harmless to the general population but can cause serious disease for the immunocompromised or in babies infected before birth (congenital CMVirus). It is estimated that 50–80% of adults have been infected with CMVirus before they are 40 years old. Once CMVirus is in a person’s body, it stays there for life and can reactivate.

CMVirus is the most common infectious cause of birth defects in the United States. And 91% of women don’t know about it.

Pregnant women may be able to lessen their risk of getting CMVirus by reducing contact with saliva, mucus, and urine from babies and young children.
