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.
Shingles is not contagious (able to spread) in the sense that people who are exposed to a patient with shingles will not catch shingles.. Anyone who has already had chickenpox or has received the chickenpox vaccine, and is otherwise healthy, should be protected and at no risk when around a patient with shingles.hingles is not contagious (able to spread) in the sense that people who are exposed to a patient with shingles will not catch shingles..
