What Is Meningococcal Disease?
Meningococcal disease refers to any illness caused by a specific bacteria that affects the meninges. The meninges are a protective membrane that surrounds the brain and spinal cord. A bacterial infection of the meninges (bacterial meningitis) can cause death within hours. This bacteria can also cause infections in the blood. The bacteria spreads easily from person to person.
It can be deadly if it is not treated right away. Most people recover, but they can have serious health problems, such as brain damage, hearing loss, and problems learning.
