What causes meningitis?

Causes of Meningitis. Meningitis is caused by two main types of pathogens.

• Bacteria: Examples include meningococcal bacteria, haemophilus influenzae bacteria and pneumococcal bacteria. Bacterial meningitis is a particularly serious disease that requires timely treatment.
• Viruses: Examples include enterovirus and herpes simplex virus.
• Both viral and bacterial meningitis can be transmitted through direct exposure to droplets or oral/nasal secretions from carriers. Healthy persons, who have no signs of illness, can carry these bacteria in their nose or throat. Close and prolonged contact, such as kissing, sneezing or coughing on someone, or living in close quarters (such as a dormitory, sharing eating or drinking utensils) with an infected person (a carrier), facilitates the spread of the disease.
