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”https://t.co/Muo96Aqcrw pic.twitter.com/PqNJYZRKan

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! https://t.co/sXLiDjSUHX

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://t.co/mRvu5H74r0

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,”https://t.co/X6w25NxVPF pic.twitter.com/ho1UIWqRM2
