What is the cause of herpes zoster (shingles)?

Herpes zoster is a painful rash that occurs along one or more dermatomes. Zoster is caused by reactivation of latent varicella zoster virus infection from a prior chickenpox infection. People who have had a prior infection with varicella zoster virus (chickenpox) are at risk of shingles.
