A member of the herpes virus group, which includes herpes simplex virus types 1 and 2, varicella-zoster virus (which causes chickenpox), and Epstein-Barr virus (which causes mononucleosis). These viruses share a characteristic ability to remain dormant within the body over a long period.

Transmission of CMV occurs from person to person. Infection requires close, intimate contact with a person excreting the virus in their saliva, urine, or other bodily fluids. CMV can be sexually transmitted and can also be transmitted via breast milk, transplanted organs, and rarely from blood transfusions.

CMV infection is important to certain high-risk groups. Major areas of concern are the risk of infection to the unborn baby during pregnancy, the risk of infection to the immunocompromised person, such as organ transplant recipients and persons infected with human immunodeficiency virus (HIV).

Recurrent disease rarely occurs unless the person's immune system is suppressed due to therapeutic drugs or disease. So, for the most people a CMV infection is not a serious problem. For more information see the CDC. If you are at risk get tested by a blood test.
