Meningococcal meningitis

Epidemics of meningococcal meningitis: Every year, bacterial meningitis epidemics affect more than 400 million people living in the 26 countries of the extended "African meningitis belt" (from Senegal to Ethiopia). In this area over 900 000 cases were reported in the last 20 years (1995–2014). Of these cases, 10% resulted in deaths, with another 10–20% developing neurological sequelae. The most recent large-scale epidemic in the Belt occurred in 2009 and affected mainly Nigeria and Niger, causing over 80 000 reported cases. From 2010 to 2014 cases have been steadily decreasing, with approximately 24 000 cases in 2010 to 11 500 cases in 2014.
