Cytomegalovirus (CMV) Transmission and Symptoms

CMV primarily spreads through direct contact with infected bodily fluids, including saliva, blood, urine, semen, and breast milk.
In healthy individuals, CMV infection often presents with mild or asymptomatic conditions; however, symptoms may include fever, fatigue, and swollen glands.

Complications in Immunosuppressed Hosts

The most serious complication of CMV infection in immunosuppressed individuals can lead to severe conditions such as pneumonia, retinitis, and gastrointestinal disease, potentially resulting in life-threatening situations.

Incubation Period and Herpesvirus Classification

The typical incubation period for a CMV infection ranges from 3 to 12 weeks after exposure, with the average being around 6 weeks.
CMV is classified as the largest human herpesvirus (HHV), exceeding the size of other herpesviruses.

Congenital CMV Infection Outcomes

Congenital CMV infection is most commonly associated with neurodevelopmental disabilities and can result in hearing loss, vision impairment, and developmental delays in affected infants.
