This document discusses fever with a purpuric skin rash and provides potential diagnoses. It begins by defining rash types and then discusses maculopapular, papular/vesicular, and purpuric rashes. Potential viral, bacterial, and immune-mediated causes are outlined for each rash type. A case scenario describes a child with fever and purpuric rash, for which meningococcal infection is identified as the most likely diagnosis. Details of meningococcal infection, meningococcemia, treatment, and importance of meningococcal vaccination are then provided.
