Meningococcal infections (including meningococcal meningitis, meningococcal septicaemia, and invasive meningococcal disease) are caused by Neisseria meningitidis, which commonly resides in the nasopharynx. In most individuals, carriage is asymptomatic; however, in a small proportion, the bacteria invade the bloodstream or central nervous system, leading to rapidly progressive and potentially fatal illness.
