In meningococcal meningitis this is caused by the bacteria invading the cerebrospinal fluid and circulating through the central nervous system. Sub ...
Although meningitis is a notifiable disease in many countries, the exact incidence rate is unknown. [22] In 2013 meningitis resulted in 303,000 deaths – down from 464,000 deaths in 1990.
