Most CMV infections are asymptomatic in healthy individuals. However, in immunocompromised persons such as organ transplant recipients, HIV-positive individuals, and those undergoing chemotherapy, CMV can cause severe and life-threatening illnesses. Symptoms may include fever, pneumonia, gastrointestinal inflammation, hepatitis, and retinitis. Congenital CMV infection can lead to hearing loss, intellectual disabilities, and other developmental problems.
