A person with shingles can pass the virus to individuals who have never had chickenpox, but these individuals will develop chickenpox not shingles. A person with chickenpox cannot communicate shingles to someone else. In order for people to develop shingles they must already harbor the virus in their nervous system, and for those who do harbor the virus, having contact with someone with chickenpox will not trigger shingles. Additionally, a person with shingles cannot communicate shingles to another individual.
