Bacteria and viruses are the two main causes of meningitis. The bacterium Neisseria meningitidis, also called meningococcus, causes meningococcal meningitis. In children and teens, meningococcus is the most common cause of bacterial meningitis. In adults, it is the second most common cause.
Pediatric bacterial meningitis is most common in children younger than 4 years, with a peak incidence in those aged 3-8 months. Male infants have a higher incidence of gram-negative neonatal meningitis. Female infants are more susceptible to L monocytogenes infection. S agalactiae (GBS) affects both sexes equally.
