Viral meningitis (0)

Viral meningitis is inflammation of the leptomeninges as a manifestation of central nervous system (CNS) infection. Viral names the causative agent, and the term meningitis implies lack of parenchymal and spinal cord involvement (otherwise called encephalitis and myelitis, respectively). Viral meningitis is also often referred to as aseptic meningitis.

In uncomplicated viral meningitis, the clinical course is usually self-limited, with complete recovery in 7-10 days. However, when the viral pathogen causes a more involved meningoencephalitis or meningomyelitis, the course can be significantly more protracted.
