So basically COVID-19 is bad air. I’m comfortable with this, but wish we all knew a lot more about the HVAC systems of the buildings we live in.
Some quotes as TLDR:
You Can Stop Cleaning Your Mail Now: People are power scrubbing their way to a false sense of security.
Surface transmission—from touching doorknobs, mail, food-delivery packages, and subways poles—seems quite rare. (Quite rare isn’t the same as impossible: The scientists I spoke with constantly repeated the phrase “people should still wash their hands.”)
Schaffner told me, “In the entire peer-reviewed COVID-19 literature, I’ve found maybe one truly plausible report, in Singapore, of fomite [surface] transmission. And even there, it is not a slam-dunk case. ”
“My point is not to relax, but rather to focus on what matters and what works,” Goldman said. “Masks, social distancing, and moving activities outdoors. That’s it. That’s how we protect ourselves. That’s how we beat this thing.”
