Common symptoms include fever, headache, confusion, seizures, and altered mental status. Patients may also exhibit focal neurological deficits depending on the affected brain regions.

Diagnosis typically involves clinical evaluation, cerebrospinal fluid analysis showing pleocytosis, and imaging studies such as MRI to identify brain edema or lesions.

Treatment often includes antiviral medications such as ganciclovir for CMV encephalitis, along with supportive care to manage symptoms and prevent complications.

While the viruses causing this condition can be transmitted, the encephalitis itself is not contagious. Infection control measures are important in healthcare settings.
