Meningitis is a deadly brain infection that causes inflammation of the tissues surrounding the brain, which helps protect the brain and spinal cord, also known as meninges. Meningitis can be caused by bacteria, virus, fungi, or parasites, but the most dangerous form of meningitis which can kill within 24 hours is caused by bacteria and requires urgent treatment. Most cases of meningitis in the United States are caused by a viral infection. It can also be caused by bacteria, parasites and fungi.
