There is a 95% chance my dad has shingles. He hasn't seen DS since before the rash appeared, so I'm not concerned about DS getting chicken pox or anything now (and DH and I have both had chicken pox and I have had the vaccine).

My question is- how long will my dad be contagious, and how long should I keep DS away from him? Besides being totally freaked out that my dad has it, and all the potential complications for him which I can't even think about, how long do you think he will be contagious? Any experience with this?
