What causes bacterial meningitis?

ANSWER

Bacterial meningitis is caused by several different bacteria. The most common ones that bring on the disease in the U.S. are:

A bacteria called Haemophilus influenzae type b (Hib) was a common cause of meningitis in babies and young children until the Hib vaccine became available for infants. There are also vaccines for Neisseria meningitidis and Streptococcus pneumoniae. They're recommended for all children as well as adults who are at a higher risk for the disease.

  • Streptococcus pneumoniae (pneumococcus)
  • Neisseria meningitidis (meningococcus)
  • Listeria monocytogenes (in older people, pregnant women, or those with immune system problems)
