Meningitis is a disease caused by the inflammation of the protective membranes covering the brain and spinal cord known as the meninges. The inflammation is usually caused by an infection of the fluid surrounding the brain and spinal cord.eningitis can be caused by viruses, like enteroviruses, arboviruses and herpes simplex viruses. Itâs serious, but less severe than bacterial meningitis, and people with normal immune systems usually get better on their own. There are vaccines to prevent some kinds of viral meningitis.
Viral infections are the most common cause of meningitis, with bacterial infections being the second most common cause. Additional and more rare causes of meningitis include parasites, fungi, and causes that are non-infectious such as ones related to drugs. Meningitis caused by a viral infection is sometimes referred to as, 'aseptic meningitis,' and is serious, although rarely fatal in people with average immune systems. The symptoms of viral meningitis usually last between 7 and 10 days, and people often experience a complete recovery.
