Very few. Covid mass infection events happened mostly through the air, much less so through touching a surface. We learned that early in the pandemic. Hand washing after the first few months was mostly kept as hygiene theatre and for preventing transmission of infections other than covid.

No, "we" didn't. The CDC and, by extension, much of the coverage was insisting on surface sanitization even though there was plenty of evidence for airborne transmission already. I distinctly remembered going with the CDC recommendations until a friend pointed me out to a bunch of published articles with a preponderance of evidence for airborne transmission. It took many months for the CDC and other agencies to change their stance, by which time the whole 'surface cleaning' was already entrenched in everyone's minds.

If you only wash your hands because of "hygiene theatre" please don't invite me to dinner.

That's not what they said. Read it again.
