I history of staph infections I had a heat rash in august that will go away with antifungal cream but always returns been using antifungal 3 months?

Heat rash. First off - staph is a bacterial infection so the anti fungal shouldn't work - heat rashes are generally non infectious and respond to products like talc power or gold bond powder if it is truly a staph infection - generally oral antibiotics are required or at least a topical antibiotic.
