What is meningococcal disease?
It is a sudden and severe illness caused by Neisseria meningitidis bacteria. It most commonly presents as meningitis or meningococcemia. The bacteria can also cause pneumonia, arthritis or pericarditis. It is spread through close or prolonged contact, usually by saliva or droplets produced by coughing. About 10% of people carry the bacteria with no signs or symptoms.
Providers must report confirmed meningococcal disease cases.
