What are the Causes of Meningitis?

Meningitis is usually caused by bacteria or viral infections.

Viruses that can cause meningitis include:

  • Enteroviruses (most common cause of viral infections)
  • Herpes simplex virus type 2
  • Varicella zoster virus
  • Mumps virus
  • HIV

Bacterial infections commonly include infection by:

  • Neisseria meningitidis
  • Haemophilus influenza B
  • Streptococcus pneumoniae

Other less common causes of meningitis include infections by fungi, amoeba and protozoa.

Non-infectious causes of meningitis include systemic diseases like SLE, sarcoidosis, polyarteritis nodosa, rheumatoid arthritis, toxins, certain medications and malignancies. Meningitis caused by non-infectious agents is called sterile meningitis because no microorganism is isolated from the spinal fluid.

Meningitis is a dangerous disease. My son had meningitis and we stayed in the hospital for 32 days. It is very costly too! The medicines are expensive. We almost lost him, too. Good thing the doctors are very good.
