Herpes zoster, commonly known as shingles, is a viral infection caused by the varicella-zoster virus, which also causes chickenpox. After a person has had chickenpox, the virus remains dormant in nerve tissue and can reactivate later in life, causing shingles. It typically manifests as a painful rash with blisters, usually affecting a specific area of the body.
