The most efficient thing to do is to actually spray your hands after touching anything dubious -- that way you can touch all the things you want, and THEN disinfect your hands directly.

Spraying your hands directly is fairly important because the most important thing when disinfecting is contact time. You need to wait anywhere from 30s to a few mins of the disinfectant touching an item before the item is safely disinfected. This is why you see "contact time" listed in the EPA's table. If you do it the other way around, you have to wait every single time, which can cause problems in public. Also, strangers don't always take kindly to you spraying an unknown substance onto surfaces that they are going to touch next haha

So if you're spraying something with IPA, and touching it directly after, there's some chance that you're getting "live" contaminants on you.

And again, it's important to stress that this particular virus cannot infect humans through skin contact. But it can infect someone if they touch a contaminated surface, and then touch their eyes/nose/mouth. This is why it's important to train yourself to not touch those areas in public -- "an ounce of prevention is worth a pound of cure"

hahaha. That's true hypo! I had so far been doing this at work, when there's pretty much nobody there. And when I spray, my hands and fingers are wet with isopropyl for a little while. I have the 'purell' sort of stuff too, just in case.

You're right about those precautions. That virus is quite formidable.

Interestingly, even though I'm a person (human) and on our side - the people's side, I recently thought (and thought of this before lots of times in the past) ---- that the virus is certainly spreading and causing issues for people and among people. But then looked at ourselves too, which also brought up the old (but maybe unoriginal) view from the very old Matrix movie ----- about how humans are pretty much on the same level as virus/bacteria. Doing similar or even much more damage to the earth and the wildlife etc. It's all natural though of course. All part of nature.
