Meningococcal disease can refer to any illness that is caused by the type of bacteria called Neisseria meningitidis, also known as meningococcus [muh-ning-goh-KOK-us]. These illnesses are often severe and include infections of the lining of the brain and spinal cord (meningitis) and bloodstream infections (bacteremia or septicemia).
Meningococcus bacteria are spread through the exchange of respiratory and throat secretions like spit (e.g., by living in close quarters, kissing). Meningococcal disease can be treated with antibiotics, but quick medical attention is extremely important. Keeping up to date with recommended vaccines is the best defense against meningococcal disease.

World Scout Jamboree
Four cases of meningococcal disease have been reported and several others are under investigation among Scottish and Swedish participants who attended the World Scout Jamboree held in Japan from July 28 – August 8, 2015. Based on currently available information, U.S. participants are at low risk. We recommend attendees be aware of the signs and symptoms of meningococcal disease and be up to date with their meningococcal vaccination.
Signs & Symptoms
Symptoms of meningococcal disease are usually sudden onset of fever, headache, and 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.
