Herpes zoster virus is an acute infectious skin disease caused by the varicella-zoster virus, which mainly manifests as erythema, blisters or papules on the skin, arranged in bands, usually along the peripheral nerve distribution area, and painful as a burning sensation, which is called herpes zoster by Chinese medicine as waist wound fire dan. Herpes zoster and chickenpox are the same pathogen. Chickenpox is extremely contagious and children with chickenpox need to be isolated, but adults with herpes zoster virus can develop an insidious infection. The herpes virus is mainly latent in the neurons of the sensory nerves and only issues herpes zoster when the immune system is low, which means that herpes zoster is a virus that is latent in the body and strikes while the body’s immune system is low.
