Therefore, it is a good time to review what meningitis is and how it is contracted. The following facts were compiled from information supplied by the National Center for Infectious Diseases, part of the U.S. Public Health Service Centers for Disease Control and Prevention. Meningitis is an infection of the fluid of a person's spinal cord and the fluid that surrounds the brain.
People sometimes refer to it as spinal meningitis.
Meningitis is usually caused by a viral or bacterial infection. Knowing whether meningitis is caused by a virus or bacterium is important because the severity of illness and the treatment differ. Viral meningitis is generally less severe and resolves without specific treatment, while bacterial meningitis can be quite severe and may result in brain damage, hearing loss, or learning disability. For bacterial meningitis, it is also important to know which type of bacteria is causing the meningitis because antibiotics can prevent some types from spreading and infecting other people. Today, Streptococcus pneumoniae and Neisseria meningitidis are the leading causes of bacterial meningitis.
