What is Herpes Zoster
Herpes Zoster, also known as Shingles, is a viral infection that results in a painful rash. The virus that causes Herpes Zoster is the same virus that causes chickenpox. After a person recovers from chickenpox, the virus remains dormant (inactive) in their body. For reasons that are not fully understood, the virus can reactivate and cause Herpes Zoster.

The cause of herpes zoster is the varicella-zoster virus (VZV). VZV is the same virus that causes chickenpox. After you have chickenpox, the virus sleeps (becomes dormant) in your nervous system. The virus can reactivate years later, causing shingles. It's not clear why the virus reactivates. However, anything that weakens your immune system can trigger the virus to become active again.
