Shingles is a disease caused by the varicella-zoster virus - the same virus that causes chickenpox. After you have chickenpox, the virus stays in your body. It may not cause problems for many years. As you get older, the virus may reappear as shingles. Although it is most common in people over age 50, anyone who has had chickenpox is at risk.
You can't catch shingles from someone who has it. However, if you have a shingles rash, you can pass the virus to someone who has never had chickenpox. This would usually be a child, who could get chickenpox instead of shingles. The virus spreads through direct contact with the rash, and cannot spread through the air.
Early signs of shingles include burning or shooting pain and tingling or itching, usually on one side of the body or face. The pain can be mild to severe. Rashes or blisters appear anywhere from one to 14 days later. If shingles appears on your face, it may affect your vision or hearing. The pain of shingles may last for weeks, months, or even years after the blisters have healed.
There is no cure for shingles. Early treatment with medicines that fight the virus may help. These medicines may also help prevent lingering pain.
A vaccine may prevent shingles or lessen its effects. The vaccine is recommended for people 60 or over. In some cases doctors may give it to people ages 50 to 59.
