What is shingles?

Shingles is a viral infection that causes a painful rash. Shingles is caused by the varicella-zoster virus. This is the same virus that causes chickenpox. The virus stays in your body after you have chickenpox, without causing any symptoms. Shingles occurs when the virus becomes active again. The active virus travels along a nerve to your skin and causes a rash. The rash usually lasts 2 to 3 weeks. Most people have shingles one time, but it is possible to develop it again.

What are the signs and symptoms of shingles?

Shingles can appear anywhere on your body, but it is most common on your torso. A line of painful blisters develops on the left or right side of your torso. The rash starts as red dots that become blisters filled with fluid. The blisters usually grow bigger, become filled with pus, and then crust over after a few days.

The virus can be passed to a person who has never had chickenpox. This usually happens if the other person comes in contact with your open sores. This person may get chickenpox, but not shingles. You are contagious until your blisters scab over. Stay away from people who have not had chickenpox or the chickenpox vaccine. Avoid pregnant women, newborns, and people with weak immune systems. They have a higher risk of infection.
