"Have you got your special stomach bug sanitizer, Hun?" My parents joke whilst they see me sanitizing when we go out to eat...it doesn't bother me as I have made my emetophobia very known over the past ten years plus they always ask for some of it haha... BUT....today it got me wondering , does it actually work?

I went to a Cafe Nero(SO GOOD) Today and went to the toilet there which was clean but there was just ONE toilet. I see young kids go in with their parents to eat and drink in Nero and I became a bit paranoid so I sat back down and whipped the gel out to spritz some on my hands. I wondered for a good five minutes after if I did happen to pick up the death virus, if it could break its way through this apparent formula ?? Anyone know if there's proof with "Norovirus effective" stuff??
