What is Shingles?
Shingles is a viral infection that causes a painful rash. Although shingles can occur anywhere on your body, it most often appears as a single stripe of blisters that wraps around either the left or the right side of your torso.
Shingles is caused by the varicella-zoster virus - the same virus that causes chickenpox. After you've had chickenpox, the virus lies inactive in nerve tissue near your spinal cord and brain. Years later, the virus may reactivate as shingles.
Who is at risk?
Shingles is most common in older adults and people who have weak immune systems because of stress, injury, certain medicines or other reasons.
Most people who get shingles will get better and will not get it again.
While it isn't a life-threatening condition, shingles can be very painful. Vaccines can help reduce the risk of shingles, while early treatment can help shorten a shingles infection and lessen the chance of complications.
