Abstract Meningococcal meningitis (MM) is a medical emergency that progresses rapidly to cause life-threatening organ failure, and a high level of suspicion is required for early diagnosis and intervention with antibiotics and fluid resuscitation. Herein, we present two cases of meningococcal meningitis in an adolescent boy and a young female child who presented with fever and rash; the purpose is to alert the emergency physicians about this life-threatening condition as early disease recognition and management is highly important for the patient’s survival.
