https://www.nature.com/articles/d41586-021-00251-4 Cleaning for an airborne illness is just theater. Upgrading air handlers, increasing airflow, and spacing people further apart matter. Cleaning stuff randomly just makes people feel better (but can make good business sense because of this!)

Yes it can make good business sense, but for those who know it's just theatre it certainly won't work.

But it's really hard to stop it when the mantra is "Better safe than sorry".

As vaccines grow in numbers and we have solid information like the one linked here, i have faith that we can return to doing things we know work.

If infection rates were double digit, the "think of what we could save" argument might perhaps deserve some consideration. But as it stands, I feel the only warranted concern is the well-being of Covid survivors.

The study used 26 participants? Did I read that right? What is the preferred sample size to back these sorts of claims?

Not sure why they'd focus on a study out this week, there have been several others, e.g. the first 5 references in this Letter published a month ago: https://www.thelancet.com/journals/ebiom/article/PIIS2352-39...

Thank you. Five studies referenced in there, with "limited participants" but complimentary results. Very cool.

I often hear from people that recovered from Covid that they don't need the vaccine, Rand Paul is one notable example, due to their natural antibodies.

I'm curious to know what the average antibody titer level of previously infected people is to start. Or how much more protection do they get once vaccinated?

Studies and research will show B, with no sign of A, however inertia/politics/fear/ignorance will continue to push A to the point of harm.

> Clean high touch surfaces daily.

A checkout belt isn't even close to a 'high-touch' surface - I don't think I've ever touched one, and neither do the checkers. And the difference between 'daily' and 4-500x daily is dramatic.
