Shingles (herpes zoster) is an infection caused by the same virus that causes
(varicella-zoster virus). Even decades after you’ve recovered from chickenpox, inactive copies of the varicella-zoster virus live within your nerves. If these viruses become reactivated, then you develop shingles.
Contact with a person who has shingles could lead to chickenpox in someone who has never had chickenpox and has not received the varicella vaccine.
If you develop shingles, you will probably first notice a burning or tingling pain in a band or line along one side of your face or torso. About three days later, you’ll see a rash appear in the same area. The rash consists of fluid-filled bumps on reddened skin that eventually crust over and begin to dry. It usually takes about five weeks to recover from shingles. Some people take longer to recover and continue to have pain in the area where the rash was previously. This complication, called postherpetic neuralgiais, is due to nerve damage.
About 20% of people who have had chickenpox will go on to develop shingles. Most people will have only a single bout of shingles. However, if you have a weakened immune system (from
, cancer, or immunosuppressant drugs, for example) you may have repeated bouts.
