We received a "tweet" from a concerned dad.  He writes: I'm sure you receive thousands of questions, but I was wondering if putting a band aid on my daughter's ringworm (on knee) will impede healing?Ringworm is very contagious and should be treated with an anti-fungal cream.  If you place a band aid over the infected area, it will hasten the healing process.

Keep following your doctor's recommendation when using her medication.  Even when the rash appears to be getting better, continue the medication (per doctor's orders) as this will help prevent the fungus from coming back.

If it looks like it is not getting better, call your pediatrician.
