The following can occur due to meningococcal infection-
Meningococcemia Meningococcemia, like many other gram-negative blood infections, can cause disseminated intravascular coagulation (DIC), which is the inappropriate clotting of blood within the vessels. DIC can cause ischemic tissue damage when upstream thrombi obstruct blood flow and haemorrhage because clotting factors are exhausted. Small bleeds into the skin cause the characteristic petechial rash, Waterhouse_ friderichsen syndrome which appears with a star-like shape. This is due to the release of toxins into the blood that break down the walls of blood vessels. A rash can develop under the skin due to blood leakage that may leave red or brownish pinprick spots,which can develop into purple bruising. Meningococcal rash can usually be confirmed by a glass test in which the rash does not fade away under pressure Symptoms. Waterhouse-Friderichsen syndrome is characterized by the abrupt onset of fever, petechiae, septic shock, and disseminated intravascular coagulation (DIC) followed by acute hemorrhagic necrosis of the adrenal glands and severe cardiovascular dysfunction Ref Harrison20th edition pg 1077
