Are germs spread by someone licking their fingers to separate papers?

My co-worker constantly licks her fingers to separate pages. Everything she touches, I also have to touch. I find this practice disgusting. Can her germs be spread to me in this manner, since I have to handle the pages also? Am I wrong to worry about this?

Yeah, there was a story where such a habit was used to kill a guy by applying some poison at the corners of pages. That means you too lick your fingers while turning pages. So unless you too lick it the germs will stay on the paper.
