Overcoming Shingles Symptoms

Someone in my office has shingles, and I have never had chicken pox. I know that I can contract chicken pox via direct contact with the rash of the person with shingles. What I’m wondering is how long the virus will last on objects. She’s gone today, but I have to do her filing, and I noticed her scratching her blisters a lot yesterday. How long can the virus live on her papers, door handles, etc?

The incubation period is two weeks, so the symptoms won’t show.
Also, your face looks like a butt.
