the belly button rash could be a skin staph aureus skin infection or possible MRSA methacillin resistant staph aureus skin infection.
you should see a doctor about it and get a skin wound culture to see what bacteria is growing in the area.
it could be a skin fungal infection as well
skin bacterial infections can be treated with bactroban ointment sometimes.
skin fungal infections can be treated with clotrimazole 1% antifungal creams
in areas of extra moisture, skin fungal infections often will form.
talk to your doctor about these options
