Natural History of Herpes Zoster (2007)

Etiology of the disorder

Herpes Zoster is caused by the same virus that causes Chicken Pox. When people have the Chicken Pox viruses from their younger years, the virus can sometimes stay inactive, living in nerve roots and become active causing “Singles”, (Another name for Herpes Zoster) in one’s adult years. People become immune to the virus after having the Chicken Pox or Chicken Pox vaccine, having a weakened immune system, or stress. Epidemiology of the disorder

Herpes Zoster infect people worldwide, it’s know to have a worldwide prevalence. The disease can only occur in people who previously had the Chicken Pox. There is a strong relationship with People with Herpes Zoster and increasing age, there’s no relationship to season or epidemics. The incidence rate of herpes zoster ranges from 2 to 3 cases per 1,000 person-years among healthy individuals, increasing to 3.9–11.8 per 1,000 person‐years among those older than 65 years, and incidence rates worldwide are similar. This relationship with age has been demonstrated in many different countries, and is attributed to the fact that cellular immunity declines as people grow older. Weinburg, JM (2007) Its pathophysiology on all body systems
