How is the shingles transmitted from host to host?

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 neuralgiaHope this helps :)

That is pretty
