What causes meningitis?
Meningitis is most commonly caused by a virus. Other causes include bacteria, fungi, parasites, chemicals, drugs, and tumors.
If the infection is bacterial, the most common bacteria include: Neisseria meningitidis, Haemophilus influenzae, Streptococcus pneumoniac, Listeria monocytogenes, Escherichia coli, Klebsiella species, and group B streptococcus. Bacteria spread through passing of respiratory and throat secretions (coughing, kissing). It is important to protect yourself by practicing good hygiene.
If the infection is viral, some common types of viruses may include: viruses that cause intestinal conditions (enteroviruses), viruses that causes cold sores and genital herpes (herpes viruses), West Nile virus, mumps and HIV virus.
Know the risk factors
What increases my risk for meningitis?
Certain factors may increase your risk of developing meningitis:
- Skipping meningitis vaccinations
- Age: Most cases of viral meningitis occur in children younger than age 5.
- Weak immune system
- Have your spleen removed
- Pregnant: If you are pregnant, you are at increased risk of contracting listeriosis — an infection caused by listeria bacteria, which also may cause meningitis
Not having risk factors does not mean you cannot get meningitis. You should consult your doctor for more information.

Treatment for meningitis depends on the cause. For most viral infections, the doctors would treat the symptoms and wait for the infection to resolve on its own. For bacterial infections, patients may require to stay at the hospital for doctors and nurses to keep a close watch.
