The African meningitis belt is a term that refers to a region in sub-Saharan Africa where meningitis outbreaks are common. It includes 26 countries stretching from Senegal in the west to Ethiopia in the east. Other terms used to describe this area include the meningitis belt, the African meningitis corridor, and the meningitis belt of Africa. The region is characterized by dry and dusty conditions during the harmattan season, which is associated with the outbreak of meningitis. The disease is transmitted through respiratory droplets and can cause inflammation of the protective membranes covering the brain and spinal cord. The use of vaccines has been effective in reducing the incidence of meningitis in the region.
