What means herpes zoster?
Herpes zoster, also known as shingles, is caused by the reactivation of the varicella-zoster virus (VZV), the same virus that causes varicella (chickenpox). Primary infection with VZV causes varicella. Once the illness resolves, the virus remains latent in the dorsal root ganglia.
What is herpes zoster and what causes it?
Shingles (herpes zoster) is a viral infection that causes an outbreak of a painful rash or blisters on the skin. It’s caused by the varicella-zoster virus, which is the same virus that causes chickenpox. The rash most often appears as a band of rashes or blisters in one area of your body.
What are the complications of herpes zoster?
Complications of herpes zoster include secondary bacterial infection, post-herpetic neuralgia, scarring, nerve palsy, and encephalitis in the case with disseminated zoster.
How many types of herpes zoster are there?
Of the more than 100 known herpesviruses, 8 routinely infect only humans: herpes simplex virus types 1 and 2, varicella-zoster virus, cytomegalovirus, Epstein-Barr virus, human herpesvirus 6 (variants A and B), human herpesvirus 7, and Kaposi’s sarcoma virus or human herpesvirus 8.
How can herpes zoster be transmitted?
The virus is spread through direct contact with the rash or through breathing in virus particles that get mixed in the air. Once the rash has developed crusts, the person is no longer contagious. A person is not infectious before blisters appear or if pain persists after the rash is gone (post-herpetic neuralgia).
Can herpes zoster cause death?
Very rarely, shingles can lead to pneumonia, hearing problems, blindness, brain inflammation (encephalitis) or death. For about one person in five, severe pain can continue even after the rash clears up. This pain is called post-herpetic neuralgia.
What is another name for herpes?

What is the difference between herpes simplex and herpes zoster?
Genital herpes is caused by herpes simplex 2. The condition we call shingles is caused by herpes zoster. Herpes zoster is the same viral infection that causes chicken pox, and the herpes zoster virus can live in the body for years after the case of chicken pox is gone, and re-emerge as the painful blisters of shingles.
How long does it take to recover from herpes zoster?
