Human betaherpesvirus 5, also called human cytomegalovirus (HCMV,HHV-5),[2] is a species of virus in the genus Cytomegalovirus, which in turn is a member of the viral family known as Herpesviridae or herpesviruses. It is also commonly called CMV.[3] Within Herpesviridae, HCMV belongs to the Betaherpesvirinae subfamily, which also includes cytomegaloviruses from other mammals.[4] CMV is a double-stranded DNA virus.[5]

Although they may be found throughout the body, HCMV infections are frequently associated with the salivary glands.[4] HCMV infection is typically unnoticed in healthy people, but can be life-threatening for the immunocompromised, such as HIV-infected persons, organ transplant recipients, or newborn infants.[3] Congenital cytomegalovirus infection can lead to significant morbidity and even death. After infection, HCMV remains latent within the body throughout life and can be reactivated at any time. Eventually, it may cause mucoepidermoid carcinoma and possibly other malignancies[6] such as prostate cancer,[7][8] breast cancer,[9] ovarian cancer[10] and glioblastoma.[11][12]

HCMV is found in all geographic locations and all socioeconomic groups, and infects between 60% and 70% of adults in the first world and almost 100% in the third world.[13] Of all herpes viruses, HCMV harbors the most genes dedicated to altering (evading) innate and adaptive host immunity and represents a lifelong burden of antigenic T cell surveillance and immune dysfunction.[14] Commonly it is indicated by the presence of antibodies in the general population.[3] Seroprevalence is age-dependent: 58.9% of individuals aged 6 and older are infected with CMV while 90.8% of individuals aged 80 and older are positive for HCMV.[15] HCMV is also the virus most frequently transmitted to a developing fetus.[16] HCMV infection is more widespread in developing countries and in communities with lower socioeconomic status and represents the most significant viral cause of birth defects in industrialized countries. Congenital HCMV is the leading infectious cause of deafness, learning disabilities, and intellectual disability in children.[17] CMV also "seems to have a large impact on immune parameters in later life and may contribute to increased morbidity and eventual mortality."[18]
