When you are stuck like this with filthy filthy filth on your hands
just keep your hands away from your eyes, mouth, nose til you can wash again. Don't touch your face and wash your hands BEFORE and after you use the loo. The general exposure is good for your immune system. It's the direct exposure (licking dirty fingers) that gets you.

In addition, clean under your nails. If you knew what grew under your nails, you'd never eat finger food again.
