191 Followers. A. 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.
Such susceptible individuals include babies, young children, and unvaccinated individuals, so people with shingles are actually contagious for VZV infections in the form of chickenpox. Consequently, these individuals may get shingles at a later time in life, as can anyone who has had chickenpox. Covering the rash that occurs with shingles with a dressing or clothing helps decrease the risk of spreading the infection to others.
