It's not hard and there is a federal role. Here's the plan.

1. Approve more rapid tests for #covid19. Subsidize and distribute them widely in drugstores and supermarkets for $1 each.

2. Subsidize or give away N95 masks. CDC should issue guidance urging use of #BetterMasks.
Again, distribute widely at drugstores and supermarkets. Make them cheap, a 3-pack for $1.

3. Approve the Corsi-Rosenthal box for schools as safe and effective. Make funds available to schools for the boxes and portable HEPA filtration machines.
4. Create a federal mask standard for the public. Have one also for child sizes. This will also be useful for wildfire-caused pollution.
5. Provide rapid tests to all schools for a test-to-stay program.

#COVID19 rapid test success story.👏👏👏

My daughter's roommate said her allergies were flaring up. All 3 double vaxxed. She gave her a rapid test. POSITIVE result. Uh oh. @michaelmina_lab

They isolated her; she canceled the x-country flight scheduled for the next day.
1/n
The test allowed them to take immediate action to prevent spread at home.

Plus protect others on the long flight she didn't take.

Plus the many people she would visit while infectious.

8 days later, my daughter and her roommate are still testing negative. 👍👍👍2/n
Roommate is feeling better, but not yet 100%.

Huge thanks and kudos to @michaelmina_lab for all he's done for rapid testing. It works.

It protected my family. It can protect yours.

Bonus -- it may have saved our Thanksgiving plans too.

Important🧵 on the exponential power of #bettermasks against #COVID19 and #Delta -- please read & retweet.

Use of #Bettermasks causes infection risk to fall exponentially by the power of two.

#Bettermasks put the power of exponential risk reduction on our side.
That's how the virus spreads -- exponentially.

That's why we need exponential powers on our side, especially against #Delta, which is 2X more infectious.
If we all wear #bettermasks, we get better filtration of exhaled air from an infector AND better filtration of your inhaled air from the infector.

We get that multiplier working for US to beat the virus!

1/ I tweeted earlier on the NIOSH report testing foreign masks. More warning bells about #KN95 masks. Many fakes. @AbraarKaran @linseymarr
@zeynep @CorsIAQ
2/ "NIOSH has been informed that many legitimate manufacturers in China have been counterfeited. In such cases, NIOSH has no way of verifying which products are counterfeit and which are authentic.
3/ "While the manufacturer listed in the table is shown as the manufacturer of the product evaluated, NIOSH has been informed that some of these are actually counterfeit products.

1/ On February 2, 2021 the National Personal Protective Technology Laboratory (NPPTL) published assessments for many foreign made masks, including KN95s. Some minimum #KN95 filtration results were < 26%! But others had >95%. @AbraarKaran @linseymarr @zeynep @CorsIAQ
2/ Before we get to the results at tweet 7, you should read the introduction. Excerpts: @nataliexdean

"[T]en respirators were submitted for evaluation. The samples were tested using a modified version of NIOSH Standard Test Procedure...
3/ "Only particulate filter efficiency was assessed. The results of these tests are for the sample tested and may or may not be representative of a larger lot or population of similar respirators.

This new mask to prevent #COVID19 is on the market. If you need solid comfortable protection, it seems like a solid product. I've not bought one yet. They are going for NIOSH approval as a respirator and I'll think they'll get it.

I looked at their test results. It seems like the best you can get.

Watch this video to learn more about the story of how it came into being.
The only uncertainty I have is how well people can hear you when you have it on. I think it is better than most reusable masks.

So it is probably best for essential workers who don't have to do a lot of talking. So not great for a teacher, for example.

Great article by @zeynep and @jeremyphoward. To answer the question they get asked what and "where to buy proper masks," below is a thread. I have no financial interest in these recommendations. My family uses this near N95 solution that costs 17-60 cents/day.
I'll tell you what to do and then I'll explain why and provide the evidence.

You need a good quality surgical mask plus a mask fitter like the one made by @FixTheMask.

A disposable face mask made out of meltblown polypropylene layer that passes the candle test is likely good. Image
Those candle grade ones appear to cost 17 cents each on Amazon. Personally I prefer to buy ASTM Level 2 or 3 certified masks. Those run 40 to 60 cents. I prefer the Ambrust, which @FixTheMask found in their testing to offer the best filtration and
