Overview, Causes, & Risk Factors
Most cases of meningococcal meningitis occur in children, from infancy to adolescence. Meningococcus is the most common cause of bacterial meningitis in children and the second most common cause of bacterial meningitis in adults.
The onset of the disease may be rapid and may start with an upper respiratory infection or sore throat. The infection occurs more often in winter or spring and may cause local epidemics at boarding schools, college dormitories, or military bases.
Risk factors include recent exposure to meningococcal meningitis and recent upper respiratory infection.
