You’re confusing different things. “Contact tracing” has nothing to do with touching things. It just means you had some kind of contact with someone who had covid. Not even physical touch, just being relatively close.
Covid does not spread well through surfaces. This created huge waste as people were trying to deep clean with isopropyl alcohol, resulting in isopropyl alcohol shortages and companies putting in more dangerous forms of alcohol in hand sanitizer. It was completely unnecessary.
In medical environments being aware of what you make contact with, aka, contact tracing, is absolutely about tracking what the hell you touched.
You leaned on that wall over there for 2.6 seconds after touching this thing contaminated with x, y, and z? Great, now we have to sanitize that, and everything that made contact with it.
Which isn’t what the covid contract tracing apps did. They just looked for proximity. Which makes sense, because covid is primarily transmitted by breathing around people.
Covid doesn’t transmit on surfaces very well.
Other things do.
Then we didn’t learn it from covid.
A big thing with COVID was contact tracing. As in, knowing who and what you made contact with that could have been contaminated with your sick.
Surfaces were nontrivial in that whole context.
If you didn’t learn contact tracing during COVID, were you even in lockdown?

Sit down.
