Hope this will clear up the confusion:
Are shingles catching?
Yes. Shingles can be spread from an affected person to children or adults who have not had chickenpox. Instead of developing shingles, these people develop chickenpox. Once they have had chickenpox, people cannot catch shingles (or contract the virus) from someone else. Once infected, however, persons have the potential to develop shingles later in life.
Shingles are contagious, to persons that have not previously had chicken pox, as long as there are new blisters forming and old blisters healing. Once all of the blisters are crusted over, the virus can no longer be spread.
