Overview
Meningococcemia is a life-threatening infection that occurs when the bacteria Neisseria meningitidis invades the blood stream. Bleeding into the skin (petechiae and purpura) usually occurs and the tissue may die (become necrotic or gangrenous). If the patient survives, the areas heal with scarring.
