You're in luck...: Shingles comes from within. A person who had varicella in childhood should have immunity to varicella, and should have varicella virus remaining inside some of his or her cells' DNA. Such a person should not be able to "catch" the virus from anyone else. However, the virus that is living in such person's DNA can form new copies of the virus, which travel to the skin surface to cause "shingles".
