More than 99% of people aged 40 or older in the United States carry the dormant chickenpox virus, also known as the varicella-zoster virus. Shingles is a reactivation of the chicken pox virus and typically occurs after age 50. The risk of developing shingles, a painful condition that causes skin blisters and can have serious complications, increases with age and other health conditions.
