Meningococcal disease refers to any illness caused by bacteria called Neisseria meningitidis. These illnesses are often severe, can be deadly, and include infections of the lining of the brain and spinal cord (meningitis) and bloodstream. Symptoms begin with fever, aches, joint pain, headache, stiff neck and photophobia. If you are experiencing these symptoms, call your health care provider.
Keeping up to date with recommended vaccines is the best protection against meningococcal disease. People spread meningococcal bacteria to other people by sharing respiratory and throat secretions (saliva or spit). Generally, it takes close or lengthy contact to spread these bacteria.
