Being on the spectrum of ADHD, I'm pretty certain that it's going to be absolutely impossible for me to stop touching my and suspect that small nervous habits of this sort just aren't going to be worked out of a significant portion of the population even if I could stop myself somehow.
I'm fortunate I can work remotely. Social distancing is a thousand times easier for me than stopping nervous habits, include touching my face. I suspect such actions are on the interface between conscious control and reflex actions.
I suppose the authorities should still keep telling us to stop doing but I think planners should pretty much assume this is not a barrier that's going to stop the disease.
I'm in a similar situation. I have a very large number of physical tics (classified as "tic disorder" and not "Tourette's" because mine are all nonverbal), and on top of that I have a massive number of sensory processing issues that make me react very strongly to any sensation on my body so I'm constantly addressing them, and I've long since decided I'd rather get the coronavirus than not touch my face. The coronavirus cause me less discomfort than not touching my face, by multiple orders of magnitude.
