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.
A. Shingles is caused by the same virus that causes chickenpox. Shingles itself is not contagious. What I mean is you cannot get shingles from someone else who has shingles. Shingles is contagious from the standpoint that you can get chickenpox from direct exposure to shingles blisters.In other words, if a person has never had chickenpox and has not been vaccinated against chickenpox, that person can get chickenpox if they come in contact with shingles blisters.t is not caused by contact with someone else. So, to answer your question, you do not need to avoid contact with your dad. You also should be aware that you can get the shingles vaccination if you're over age 50, even if you've had an outbreak of shingles in the past.
