Viral meningitis not elsewhere classified, unspecified is typically diagnosed based on a combination of physical signs and symptoms, including fever, headache, nausea, vomiting, and stiff neck. A lumbar puncture is also necessary to identify the presence of the virus and to rule out bacterial meningitis.
Differential diagnosis includes bacterial meningitis, fungal meningitis, and other viral infections.
Treatment typically consists of supportive care, such as fever reducers and pain relievers. Antiviral medications may be prescribed if the virus is identified.
