"Shingles is the result of a new varicella-zoster virus infection, while chickenpox is caused by reactivation of the virus later in life."

"Both chickenpox and shingles affect only one side of the body, but shingles is more likely to leave scars."

"Chickenpox typically causes a widespread rash across the body, while shingles produces a painful, blistering rash in a single band along one side of the body."

"Chickenpox and shingles cause similar skin symptoms, but shingles usually affects younger patients who have not yet had chickenpox."
