Do I have the possibility of getting norovirus?

And if so, is it possible to prevent it?

Just found out a coworker has stayed home today because she caught it. I’m paranoid now because I helped her move some boxes and whatnot yesterday and was in close proximity.

I don’t have any symptoms, but is it possible for me to do something ahead of time so I won’t catch it? I know it’s apparently contagious before symptoms show…

I know this might sound silly, but I explained a long time ago that I’m emetophobic: can’t stand vomit and whatnot.
