Pathophysiology: Meningitis is an inflammation of the tissue lining that covers the brain and spinal cord. The pathogenesis of each family of viruses that causes viral meningitis varies. It is uncommon complication of common systemic infections. In children some studies shows learning disabilities, neuromuscular impairments (ie, mild paresis or loss of coordination), and deafness to viral meningitis. Communicating hydrocephalus is a rare complication of viral meningitis.
Disease Statistics: Enterovirus infection was the most common cause of viral meningitis in United Kingdom. Among others are herpes simplex virus (HSV), and varicella zoster virus (VZV) infections in immunocompetent adults.
Treatment: For most of the cases, there is no specific treatment for viral meningitis. Mostly people completely recover on their own within 7 to 10 days. However disease from certain viruses such as herpesvirus and influenza requires treatment with an antiviral medication. Antibiotics are useful only in cases of bacterial meningitis.
Research: In recent times, more study has been done on the different strains of enterovirus. Royal Hallamshire Hospital, Sheffield is among the centre for research study and pathophysiology.
