COVID-19 Outbreak Information Updates (Reboot) [over 150.000,000 US cases (est.), 6,422,520 US hospitilizations, 1,148,691 US deaths.]

And, if anything, that last post article was really advocating n95, kn95, or surgical masks should be the only ones allowed because they are most effective.

Now, they didn't enforce it much once people got inside at their seats. But that's a whole other thing.
