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 highly contagious. The virus is spread through direct contact with fluid from the blisters. The virus cannot be transmitted to others by sneezing, coughing or casual contact. How to prevent the transmission of shingles to others: 1  If you have shingles, keep the rash covered. 2  Do not touch or scratch the rash. 3  Frequent hand-washing helps prevent the spread of the virus. 4  Until your rash or blisters have developed scabs, avoid contact with pregnant women who never had chickenpox.
