 The 'meningitis belt' of tropical Africa is the zone lying between 5° and 15° N of the Equator, and characterised by an annual rainfall between 30 and 110 cm. The disease however is not limited to Africa. Overcrowding enhances the risk of acquiring the infection. Nearly 3000 people died from meningitis in two Brazilian cities in 1974. Effective vaccines against types A and С are now available.
