On the other hand, pathogens survive longer on a smooth surface than on a rough absorbant surface, and I would guess that they are more likely to be transferred from a smooth surface onto somebody's hand than from a rough absorvant surface. So, taking account of people perhaps not doing all that spraying and wiping properly, a paper menu might turn out to be safer after all.

- Symmetry 5y agoIn March of 2020 we were pretty sure that at most 5% of Covid transmissions were through touched surfaces (fomites). Currently we're sure that at most .01% of Covid transmissions are through surfaces and still haven't found clear evidence of it ever actually having happened so literally 0% still can't be ruled out. But upper respiratory tract infections like the flu do actually spread through fomites pretty easily so we've defaulted to the flu playbook for many public health measures.
