"Herpes zoster, also known as shingles, is a painful cutaneous eruption that develops following the reactivation of the varicella zoster virus (VZV), the same virus that causes chickenpox.1 About 1 in 3 people in the United States will develop shingles, with an estimated 1 million cases occurring annually. Anyone with a history of chickenpox is at risk for shingles, but the risk increases with age and in patients who are immunocompromised.2"
