how long is shingles contagious

a lady at my new job had shingles last week. She is supposed to train me on Tues. Is she still contagious? I need to know for sure, because we share phones and stuff behind a desk. I've had chicken pox when i was a kid, but still. Also my 5 year old hasn't had chicken pox and i don't want to bring something home to her. So after a week of her getting shingles, is she contagious?


Herpes zoster (or simply zoster), commonly known as shingles, is a viral disease characterised by a painful skin rash with blisters in a limited area on one side of the body, often in a stripe. The initial infection with varicella zoster virus (VZV) causes the acute (short-lived) illness chickenpox, and generally occurs in children and young people. Once an episode of chickenpox has resolved, the virus is not eliminated from the body but can go on to cause shingles—an illness with very different symptoms—often many years after the initial infection.

The rash and pain usually subside within 3 to 5 weeks. Many patients develop a painful condition called postherpetic neuralgia, which is often difficult to manage. In some patients, herpes zoster can reactivate subclinically, with pain in a dermatomal distribution without rash.

Shingles cannot be passed from one person to another. However, the virus that causes shingles, VZV, can be spread from a person with active shingles to a person who has no immunity to the virus by direct contact with the rash, while in the blister phase. The person exposed would then develop chicken pox, not shingles. The virus is not spread through airborne transmission, such as sneezing or coughing. Once the rash has developed crusts, the person is no longer contagious. A person is not infectious before blisters appear or with post-herpetic neuralgia (pain after the rash is gone).
