Does laying down toilet paper when in a public bathroom dramatically help keep away pathogens?

You are incredibly unlikely to ever catch anything, even if you sat in poop, from a toilet seat unless you are immunocompromised (e.g. HIV+, current chemotherapy, on immunosupressants) or you have open wounds in that area. If this was at all even remotely common you'd hear about it. Don't waste paper.

You've got an immune system and it kicks ass at its job. There's nothing to be worried about. You are much, much more likely to get sick if you don't wash your hands and then end up eating, putting your hands in your mouth, or touching your eyes or nose.

Wash your hands when you're done with the bathroom then dry your hands on a paper towel and use that to open the door. If there's no paper towel grab some toilet paper to open the door. It's that important.
