This should clarify things...
7. Can shingles be spread to others?
Shingles cannot be passed from one person to another. However, the virus that causes shingles, VZV, can be spread from a person with active shingles to a person who has never had chickenpox through direct contact with the rash. The person exposed would develop chickenpox, not shingles. The virus is not spread through sneezing, coughing or casual contact. A person with shingles can spread the disease when the rash is in the blister-phase. Once the rash has developed crusts, the person is no longer contagious. A person is not infectious before blisters appear or with post-herpetic neuralgia (pain after the rash is gone).
Basically, Shingles is a recurrence of an old chicken pox infection which lies dormant within the body of anyone who has had chicken-pox in the past.
I think they often don't know what cause shingles, but poor immunity, stress and old-age are considered factors.
However, because chicken-pox and shingles are caused by the same virus, a person who hasn't had chicken-pox could catch it from a person with shingles.
That person would suffer from chicken-pox not shingles.
So yes, if you've had chicken-pox as a child you should be fine!
