Cytomegalovirus (CMV) Infection: Symptoms & Signs

Medically Reviewed on 9/10/2019

A cytomegalovirus (CMV) infection is a viral infection with a member of the herpes virus family. Cytomegalovirus infection is very common and typically does not cause any symptoms or signs.

Most people have antibodies to CMV infection, indicating that they have been infected with the virus at some point in life. In young children or those who have not had an infection, the virus can cause a syndrome similar to infectious mononucleosis, with fever, tiredness, sore throat, swollen glands (enlarged lymph nodes), night sweats, joint pain, appetite loss, and muscle pain.

Cause of cytomegalovirus infection

CMV infection spreads from person to person through contact with body fluids (including saliva, blood, urine, semen, vaginal fluids, and breast milk) of a person infected with cytomegalovirus.
