Herpes Zoster (Shingles)

Herpes zoster, also called shingles, is an infection caused by the varicella virus. This is the same virus that causes chickenpox. Herpes zoster only develops in people who have had chickenpox in the past. After your chickenpox are gone, the varicella virus stays in your body as an inactive virus. This means that you may not feel symptoms, but the virus is still in your body. When the varicella virus becomes active again, it causes herpes zoster.
