Cytomegalovirus (CMV)

Cytomegalovirus (CMV) is a common viral infection that infects people of all ages. More than half of adults have been infected with CMV by age 40. Most people infected with CMV show no signs or symptoms. It rarely causes disease in healthy people.

When it does cause disease, the symptoms vary depending on the patient's age and immune status.

In some cases, infection in healthy people can cause mild illness that may include:

• Fever
• Sore throat
• Fatigue
• Swollen glands
