My grandson (who lives with us) has been exposed to impetigo, which I understand is a contagious bacterial skin infection, sometimes a strep infection, and sometimes staph. I'm only 7 weeks out from a six month treatment of steroids and just finished antibiotics for bronchitis. Should I be worried? (Seems like I get an infection every time my GS is sick.)

I guess I know what to look for symptom wise, but how paranoid should I be? Open to suggestions.
