Cytomegalovirus (CMV) infection
Infectious diseases
General description
Cytomegalovirus (CMV), a member of the herpesvirus family, often leads to subclinical infections in numerous individuals. However, in immunocompromised patients, such as those with HIV infection or under immune suppression, it can cause encephalitis among other symptoms.
The manifestation of CMV in the central nervous system progresses subacutely over days to months, characterized by fever, loss of consciousness, and dementia. CMV infection notably affects the ventricles and the retina.
