HEALTHIER YOU: What is Cytomegalovirus?

BY DR. ANNETTE MAYES, OB/GYN

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. 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 be re-infected with a different strain of the virus. Most people with CMV infection have no symptoms and aren’t aware that they have been infected.

In some cases, infection in healthy people can cause mild illness that may include: fever, sore throat, fatigue, and swollen glands. Occasionally, CMV can cause mononucleosis or hepatitis (liver problem).

People with weakened immune systems who get CMV can have more serious symptoms affecting the eyes, lungs, liver, esophagus, stomach, and intestines.

Babies born with CMV can have brain, liver, spleen, lung, and growth problems.

The most common long-term health problem in babies born with congenital CMV is hearing loss, which may be detected soon after birth or may develop in childhood.

People with CMV may pass the virus in body fluids, such as saliva, urine, blood, tears, semen, and breast milk. CMV is spread from an infected person in the following ways:

• From direct contact with saliva or urine, especially from babies and young children.
• Through sexual contact
• From breast milk to nursing infants
• Through transplanted organs and blood transfusions.

Blood tests can be used to diagnose CMV infection in adults who have symptoms. However, blood is not the best fluid to test newborns with suspected CMV infection. Tests of saliva or urine are preferred for newborns.

Healthy people who are infected with CMV usually do not require medical treatment. Medications are available to treat CMV infection in people who have weakened immune systems and babies with signs of congenital CMV.
