different kinds of shingles virus
Shingles (also termed herpes zoster or zoster) is a disease caused by reactivation of a previous infection with the herpes zoster virus (also named varicella-zoster virus, VZV, HHV-3, or chickenpox virus) that results in a painful localized skin rash, usually with blisters (fluid-filled sacs) on top of reddish skin. Risk factors for shingles are common, and the majority of people have at least one or more risk factors. 2  For example, anyone who has had the chickenpox infection or chickenpox vaccine (live attenuated virus) may carry the herpes zoster virus that causes shingles.
