Where is shingles commonly found? This is one of the most frequently asked questions by patients and their health care providers. Shingles is a condition caused by the varicella-zoster virus (VZV), a virus that can cause painful blisters that bulge from the skin, especially in areas of skin exposed to moisture. This type of virus is more often to be transmitted by children under the age of five. It is also passed by touching things that have been shared by an affected individual. The symptoms can initially be mild and will gradually develop into a more severe condition.
