What is bacterial meningitis?

Bacterial meningitis is often severe and is considered a potential medical emergency. If left untreated, bacterial meningitis may be fatal or cause serious long-term complications. Because bacterial meningitis can progress rapidly, it is important

to identify the bacteria and begin antibiotic treatment as soon as possible.

Acute bacterial meningitis is a true medical emergency, and requires immediate hospital-based treatment. Bacterial strains that cause meningitis include Streptococcus pneumoniae, Haemophilus influenzae, Neisseria meningitidis (meningococcus), Listeria monocytogenes, and many other types of bacteria. In the U.S. about 17,500 cases of bacterial meningitis occur each year.

Bacterial infection in the ears, mouth, or sinuses can spread directly to the brain and spinal cord. Some types of bacteria are transmitted from person to person through secretions from the mouth and nose.

The bacteria are spread among people by coughing, sneezing and kissing. These bacteria cannot live outside the body for long, so they cannot be picked up from water supplies, swimming pools, or a building's air-conditioning system.

Individuals can carry these bacteria for days, weeks, or months without becoming ill. In fact, about 25 percent of the population carries the bacteria. Only rarely do the bacteria overcome the body's defenses and invade the cerebra spinal fluid, causing meningitis.
