Inflammation of meninges leading to meningitis. In addition to retrograde propagation from nerve endings and bloodstream transmission, viruses can also reactivate from a dormant condition inside the nervous system and go to the meninges, composed of three layers, resulting in an inflammatory reaction brought on by a virus as it progresses through the subarachnoid space and reaches the CNS. The prognosis is worse for encephalitis, which happens when the brain parenchyma is inflamed
