an acute infectious disease of children and young adults, caused by Neisseria meningitidis and characterized by fever, headache, photophobia, vomiting, nuchal rigidity, seizures, coma, and a purpuric eruption.

meningococcal meningitisAn epidemic form of MENINGITIS, sometimes called cerebrospinal fever or spotted fever, and commoner in children than in adults. The organism responsible, Neisseria meningitidis , is spread by coughed or sneezed droplets. There is early leg pain, cold hands and feet, pallor or mottling of the skin, then a sore throat, fever, severe headache, marked neck stiffness and vomiting. A rash of red spots appears on the trunk and the affected person may be gravely ill within a day of onset and quickly become confused, drowsy and comatose. Without treatment, death may occur within days or even hours but an intensive course of antibiotics is usually successful, resulting in full recovery. Vaccines are available. Contacts are sometimes given protective antibiotics.
