Our #pandemic global strategy:
"If I paint a rosy picture, will you promise not to cry?"

1/5 Image Written a decade ago, the article was about how clinicians too often falsely reassured patients w/terminal #cancer that treatment was working just fine.

There are many parallels b/w cancer cancer, the pandemic, & climate change.

Mortality salience elicits #denial.

If you're advocating for more cautious and compassionate COVID policies or generally "doing the right thing," please keep pushing.

I've had three extremely validating interactions in the past week I wish to share (details disguised).... #1 - A vulnerable family member had a cable guy come to her home. The cable guy refused to mask, so she refused to let him in and called to complain to the cable company. One of those big, hated cable companies.

Know what they did? Fired him on the spot. 🔥

I've yet to see a well-designed study showing that #COVID #RapidTests are no longer efficacious.

This one is no exception. Why?
5 reasons.

clinicalmicrobiologyandinfection.com/article/S1198-… Image 1. They compare same-day PCR against self-administered/interpreted rapid tests.

For most ppl, that's not reality. It's RAT today or PCR result in 1-3 days (or do both).

A fairer comparison would be a RAT today versus a PCR yesterday (since you'd have to wait for results).

Cloth masks could be customized to look amazing. BUT they offered weak protection (poor filtration, many gaps).

What if you could safely customize an N95 or #BetterMask with a small logo, decal, or other decoration?


1/ 3M N95 with monotone cancer ribbon (or interpret as another H/T 🎩 to @amandalhu for recommending rub-on “dry transfers.”

Follow her & see her amazing thread of several examples. Very fun, especially for kids. Many pre-designed options.

I made a new graphic representing my current gist-level representation of the #SwissCheese Model of #COVID mitigation.

In your mind, how do you organize the categories differently? Is there something else you prioritize?
1/5 Swiss Cheese model of COVID... My mental model of COVID mitigation differs from others in that it gives more weight to secondary and tertiary prevention.

The less the Western world focuses on the first 8 slices of cheese, the more we will need to focus on the final 2-3 slices.

As hospitals drop universal COVID protections, these are my top 7 tips for protecting unmaskable un-vaxable newborns from #nosocomial (hospital-acquired) COVID.

What did I miss?

THREAD of Top 7 Tips 🧵 Tip #1 – Determine your #mask rules. Some parents require staff to #N95. Compliance would vary by region/hospital. Prep for what you’ll say if staff don’t comply.

With our newborn twins, we supplied medical staff w/free N95s & tests. Nobody wanted N95s; 1 took a #RAT. 🤣

Such a proliferation of useless #COVID "treatments," now nasal irrigation.

If a virus kills millions of people, a useful treatment would be published in a journal with impact factor >20, not 1.7.

journals.sagepub.com/doi/full/10.11… The study gave people nasal irrigation and compared it to CDC data on hospitalization and death rates.

Not everything must be an RCT, but the purpose of an RCT is to compare two equivalent groups so that the observed differences can be attributed to the treatment.

Do you know any #parents looking for better #masks for their kids this fall?

Check out all the helpful comments on this Tweet.

Best for many: @flo_mask & 3M Vflex 9105s
Popular: WellBefore, Powecom, Lutema, Vitacore

1/3 The child #MentalHealth clinic I was helping out ended up purchasing the WellBefore masks. Useful in this context b/c they needed disposables in plenty of different sizes.

The clinic runs somewhere between 12-18 ACH to help w/ imperfect mask fit.

Top 10 tips everyone should know about wearing #N95 & #elastomeric masks.

What did I miss?

THREAD! Image Tip #1: Masks buy time. Context matters too: Ventilation (HVAC/outdoor air), filtration (HEPA), & ⬇️ people buy more time.

The longer you’ll be someplace or the worse the context, the better the mask you’ll need.

In a “typical” setting, you might expect this (per @akm5376): Image

Kids <2 yrs old can’t mask.
Kids <6 months can’t vax.

Many parents are using strollers w/rain covers to try to get some protection during essential activities.

Does adding a #PAPR or #HEPA device help?

I tried 6 models: engrxiv.org/preprint/view/…

1/10 Image First off, thanks @RealSexyCyborg for the original design. Thanks to @ccwake1, @gjmf, @drgregkelly for ideas too. Happy to acknowledge!

My goal was to test 6 models & help relate them to non-engineers.
