Shingles>>>http://www.medicinenet.com/shingles/article.htm

   A person must have already had chickenpox in the past to develop shingles. A person can not get shingles from a person that has it. However, the virus that causes chickenpox and shingles can be spread from a person with active shingles to a person who has never had chickenpox or been vaccinated 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 if pain persists after the rash is gone (post-herpetic neuralgia).

I had shingles about 15 years ago, it's very painful. My doctor told me at the time that it was not infectious, but that it came from the chickem pox virus which you had as a child, he said it lays dormont in your body and them comes back to life as shingles later in life.I'm not sure if you can have it more than once, I don't think so, and I don't think you can pass it on. Well not according to my doctor and my expierence. But as country bumpkin says the chicken pox virus spreads easy from one person to another.
