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: In Australia, the annual incidence of bacterial meningitis is approximately 3 cases per 100,000 population. Factors as geography, ethnicity, socio-economic status and availability of immunisation play crucial role.
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: Some of the major centres working in this field in Australia are Virtual medical centre, the meningitis centre and brain foundation and Government of Western Australia Department of Health.
