Shingles is contagious and can be spread from an affected person to babies, children, or adults who have not had chickenpox. But instead of developing shingles, these people develop chickenpox. Once they have had chickenpox, people cannot catch shingles (or contract the virus) from someone else.
You can only get shingles if you have had chickenpox. But if someone has shingles, then the watery stuff from the blisters can give someone else chicken pox if that person hasn't had it.
