What are the 5 causes of meningitis?

Meningitis is usually caused by a viral or bacterial infection.

  • meningococcal bacteria – there are several different types, called A, B, C, W, X, Y and Z.
  • pneumococcal bacteria.
  • Haemophilus influenzae type b (Hib) bacteria.
  • enteroviruses – viruses that usually only cause a mild stomach infection.
  • the mumps virus.

How is Neisseria transmitted?

Summary. Neisseria meningitidis is an obligate human commensal bacterium that frequently colonises the upper respiratory tract. Person-to-person transmission occurs via direct contact or through dispersion of respiratory droplets from a carrier of the bacteria, and can lead to invasive meningococcal disease.
