Meningococcal disease refers to any illness that is caused by Neisseria meningitidis bacteria. The two most severe and common illnesses caused by these bacteria include infections of the tissue covering the brain and spinal cord (meningitis) and bloodstream infections (bacteremia or septicemia).
Symptoms of meningococcal disease may include sudden onset of a high fever, headache, or stiff neck. It can start with symptoms similar to influenza (flu), and will often also cause nausea, vomiting, increased sensitivity to light, rash, and confusion. If you think you or your child has any of these symptoms, call the doctor right away.
