Masking Rules
Why the CDC Changed Them
On Feb 8, 2021 I wrote, “There’s no science yet showing you should double mask.” On February 10, 2021, boom, the CDC published new science showing just that.
Because, boom, that’s how it works. Science marches on and with Covid more than ever we need to keep our science game up.
The CDC prioritized mask studies throughout January. They did new mask experiments and it turned out they showed much less particle transmission using double masking or tight masks so they have now changed their recommendations to reflect hat.
This is a good reminder once again about three things:
a) with Covid we need to stay humble and open and non-smug about everything because it is a wily virus and
b) science marches on and
c) this is how science works. One study leads to a hopefully better one which leads to another even more refined one.
So just a little background.
When a new bug/disease comes along, the first thing we need to figure out is how you catch it. Because as soon as we figure out how you catch it, then we can investigate how you can KEEP from catching it.
With malaria, you get it from a mosquito. With norovirus and most “cruise ship” infections…
