meningococcal meningitis

me·nin·go·coc·cal men·in·gi·tis

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. Even in the absence of meningitis, meningococcemia can induce toxic phenomena such as vasculitis, disseminated intravascular coagulation, shock, and Waterhouse-Friderichsen syndrome due to adrenal hemorrhage; late complications include paralysis, mental retardation, and gangrene of the extremities. Synonym(s): cerebrospinal fever, epidemic cerebrospinal meningitis

meningococcal meningitis

Meningeal infection by Neisseria meningitidis, primarily of children, typically of rapid onset after an upper respiratory tract infection (URI).

Epidemiology

me·nin·go·coc·cal me·nin·gi·tis

(mĕ-ning'gō-kok'ăl men-in-jī'tis) An acute infectious disease affecting children and young adults, caused by Neisseria meningitidis; characterized by nasopharyngeal catarrh, headache, vomiting, convulsions, stiffness in the neck (nuchal rigidity), photophobia, constipation, cutaneous hyperesthesia, a purpuric or herpetic eruption, and the presence of Kernig sign. Fulminant form may cause Waterhouse-Friderichsen syndrome.

meningococcal meningitis

An 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.
