Meningitis, often known as spinal meningitis, is an infection of the spinal cord. It is usually the result of a viral or bacterial infection. Bacterial meningitis is more severe than viral meningitis and may cause brain damage, hearing loss, and learning disabilities. An estimated 1.2 million cases of bacterial meningitis occur every year, over a tenth of which are fatal. Symptoms include severe headache, fever, nausea, vomiting, lethargy, delirium, photophobia, and a stiff neck.
