What is bacterial meningitis?

ANSWER

Bacterial meningitis is serious, occurring more often in winter months. A common cause affecting teens is the bacterium Neisseria meningitidis, which causes meningococcal disease. It can be fatal if you don't receive treatment right away. The bacteria that cause it live in the noses and throats of up to a quarter of the population. It is not known why these bacteria sometimes travel to the nervous system and cause meningitis. Another leading cause of bacterial meningitis is Streptococcus pneumoniae.
