Dorothy: That is an interesting question, and the answer is, yes and no. As you probably seem to know, Shingles (In an adult, so named because of the painful projections of tissue that erupt on the back)is caused by the same virus as Chicken Pox in children. Getting that simple bit out of the way, I will see if I can answer your question. The 'Yes' part is that, if, as an adult you are exposed to a child with Chicken Pox, and you have either a.) Never had it, or b.) Not been vaccinated against it, you could develop Shingles subsequent to getting your 'original' case of Chicken Pox. There is no obvious connection between re-exposure to the virus and development of Shingles. In fact, it is presumed that periodic re-exposures to the Varicella virus may boost immunity to the organism and prevent Shingles. Shingles often emerges due to a diminished immune system from old age, organ transplant therapy, or other immuno-compromising conditions; (Such as HIV). So, yes exposure to a child with Chicken Pox can eventually cause Shingles in an adult, but most evidence indicated that this will not 'trigger' an outbreak of Shingles. I hope this answers your question. Good luck learning about viruses and pathology. -Matt-
