Shingles is a virus that is caused by the same virus that causes chickenpox, the varicella-zoster virus. Shingles are found in most people who had chickenpox because the varicella-zoster virus is dormant in the nerve tissue by your spinal cord and brain. The virus can become active again years after you suffered from chickenpox.
