What Is It?
Meningitis is an inflammation of coverings (meninges) of the brain and spinal cord. Most often it is caused by a viral or bacterial infection. Other infectious agents such as fungi can also cause meningitis. Rarer causes of meningitis include atypical drug reactions and systemic lupus erythematosus. Viral, or aseptic, meningitis is the most common type. In general, viral meningitis is not directly contagious. Anyone can get viral meningitis, but it occurs most often in children. Many different viruses can cause meningitis; an enterovirus tends to be the usual culprit.
