Meningitis is an infection of the membranes surrounding the spinal cord. The most common causes of meningitis are infections from viruses, fungi, bacteria, or parasites. It could also be caused by cerebrospinal liquid encircling the brain and spinal cord, a physical injury, or reactions to certain drugs. It is usually caused by the spreading of an infection around the brain and spinal cord in a human's body. It is a very dangerous disease.

In the past, most cases were seen in children under five years old. Because of current childhood vaccines, most cases are now seen in young men and women between the ages of fifteen and twenty-four. There have been incidents in older adults, as well. Meningitis affects countries in West Africa every year between February and late May. The largest epidemic of meningitis occurred in 1996. There were at least two hundred fifty thousand cases and twenty-five thousand deaths.
