Zoster (Shingles)
Description
Shingles, also known as herpes zoster, is a viral infection caused by the reactivation of the varicella-zoster virus (the same virus that causes chickenpox). After a person recovers from chickenpox, the virus can remain dormant in the nerve tissues and reactivate years later, causing a painful rash, typically on one side of the body. Symptoms include itching, burning, and a red rash that develops into fluid-filled blisters. Antiviral medications can help reduce the severity and duration of the infection, and pain relievers can manage discomfort. A vaccine is available to help reduce the risk of shingles in older adults.
