Herpes zoster is caused by reactivation of varicella zoster virus latent in the cranial ganglion or posterior root ganglion of the spinal cord. It tends to occur in the elderly and hypo-immunity people. With the aging of the global population, the changes of herpes zoster epidemiology deserve academic attention.
