All are true about post meningococcal reactive disease, EXCEPT:

It is immune complex related problem, develops 4-10 days after the onset of meningococcal disease, with manifestations that include a maculopapular or vasculitic rash, and polyserositis with fever. These features resolve spontaneously without sequelae. No need to treat/prophylaxis with antibiotic. Ref: Harrisons Principles of Internal Medicine, 18th Edition, Page 1215
