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 cannot catch shingles from someone who has shingles. You can, however,catch chickenpox from someone who has shingles. If you are not immune to the varicella zoster virus and you are exposed to someone who has shingles there is a very small chance that you could develop chickenpox.f you do develop shingles, make sure you contact your health care provider right away. The most common symptom is a painful rash on one side of the face or body. The rash forms blisters that typically scab over in 7â10 days and clear up within 2â4 weeks.
