Neisseria meningitidis: presentation, treatment, and prevention

Abstract

Neisseria meningitidis is a leading cause of meningitis and septicemia in children and young adults in the United States. Highly publicized outbreaks of disease caused by this organism in communities and on college campuses have resulted in a heightened public awareness of its potentially devastating effects. The rapid progression of signs and symptoms of meningococcemia necessitate early recognition and institution of appropriate therapeutic measures. Identifying contacts of index cases who are at high risk of acquiring the disease allows health care providers to institute appropriate chemoprophylaxis. During community outbreaks, health care providers play an equally important role in calming the fears of low-risk contacts and their families. Familiarity with the risks and benefits of the meningococcal vaccine allows health care providers to offer this immunization to appropriate patients.
