Meningococcal disease is caused by a bacterium known as meningococcus. Some people carry this germ in their throat or nose without getting sick. In rare instances, the germ overcomes the body's natural defences, and causes serious diseases, including bacterial meningitis (an inflammation of the tissue surrounding the brain and spinal cord), and meningococcemia (a widespread infection of the blood and other organs).
The symptoms of meningitis include high fever, headache, stiff neck, vomiting and drowsiness. Other symptoms of meningococcal disease might include sensitivity to bright light (photophobia), confusion, and a purplish skin rash. Anyone with these symptoms should seek immediate medical attention.
Meningococcal disease is serious, and sometimes fatal. Approximately 10 percent of people who develop the disease will die. In addition, about 10 percent of those who recover will have long-term complications. These can include deafness, brain damage, problems with the nervous system and seizures, and may result in amputation of one or more limbs.
