2) lol: “Try not to be so grouchy. Have some faith in Fauci!”

3) And MASKS do work!!

Association Between Universal Masking in a Health Care System and SARS-CoV-2 Positivity Among Health Care Workers

4) A big scientific evidence review study on face masks.

“We recommend that public officials and governments strongly encourage the use of widespread face masks in public, including the use of appropriate regulation.” #COVID19 https://europepmc.org/article/PPR/PPR186793

5) Another big study on #masks.

“As a result of the implementation (mask) mandates, more than 200,000 COVID-19 cases were averted by May 22, 2020. The findings suggest that requiring face mask use in public could help in mitigating the spread of #COVID19”

6) Here is meanwhile a recent CDC @CDCMMWR report on Arizona outbreak. Masks clearly indicated to have helped. #COVID19 #Masks https://www.cdc.gov/mmwr/volumes/69/wr/mm6940e3.htm

7) Another case on mask protecting an infectious person on a plane from infecting anyone else because he wore a #mask. https://twitter.com/Atul_Gawande/status/1317619176761118721

8) that said, *cloth* masks are only as good if everyone wears them. Masks work if entire or vast majority of people wear them. But this doesn’t happen during indoor dining and bars or airplanes.

For self protection if many don’t wear around you, premium masks likely needed. https://twitter.com/atul_gawande/status/1317619177700601856

9) Back to the Beauty & The Beast (not sleeping beauty—sorry sleepy) mask video - here is the YouTube of Noah Lindquist who made and uploaded it. I’m not certain of his Twitter tag, but if someone verifies who he is on twitter, tag him. Thanks Noah!

10) Another study (preprint) on masks and deaths.

“Conclusions. Societal norms & govt policies supporting wearing of masks by the public, as well as international travel controls, are independently associated w/ lower per-capita mortality from #COVID19”
https://www.medrxiv.org/content/10.1101/2020.05.22.20109231v5

11) A lot of people ask about “premium masks”. I don’t use N95 - save those for HCW. I use KN95 and S Korean KF94. And I sometimes double up indoors when cant distance. KF94s are quite comfortable actually and widely used in South Korea https://twitter.com/drericding/status/1316191229655363584

12) While you can order premium masks like KN95 & KF94 online (Eg Amazon), I don’t know which are fakes / real. That said, KN95’s also sold in stores like @StaplesStores. Hopefully they vetted their products for authenticity. That’s also why I double mask—in case one is fake.

13) Finally, Trump misled people on masks:

“he repeated an incorrect claim about masks, citing a recent report from CDC.”

So CDC tweeted back:

“The interpretation that more mask-wearers are getting infected compared to non-mask wearers is incorrect,”

14) Folks—we know the video creator is named Noah Lindquist. There has been confusion over which person on twitter is that Noah— @noahlindquist96 is the man!

15) updated thread now with proper credit to @noahlindquist96. https://twitter.com/drericding/status/1317961637442314242
