Lunchtime pandemic reading.
Standard disclaimer: this is a roundup of informative pieces I've read that interest me on the severity of the crisis and how to manage it. I am not a qualified medical expert in ANY sense; at best I am reasonably well-read laity. ALWAYS prioritize advice from qualified healthcare experts over some person on Facebook.

Read the internal CDC memo pretty much everyone in non-medical media is misquoting or misunderstanding. It's 25 slides, worth your time. Here are the key takeaways:
"Summary
▪ Delta is different from previous strains
– Highly contagious
– Likely more severe
– Breakthrough infections may be as transmissible as unvaccinated cases
▪ Vaccines prevent >90% of severe disease, but may be less effective at preventing infection or transmission
– Therefore, more breakthrough and more community spread despite vaccination
▪ NPIs are essential to prevent continued spread with current vaccine coverage
Next steps for CDC
▪ Communications
– Acknowledge the war has changed
– Improve public’s understanding of breakthrough infections
– Improve communications around individual risk among vaccinated
• Risk of severe disease or death reduced 10-fold or greater in vaccinated
• Risk of infection reduced 3-fold in vaccinated
▪ Prevention
– Consider vaccine mandates for HCP to protect vulnerable populations
– Universal masking for source control and prevention
– Reconsider other community mitigation strategies"

Commentary: What we've been saying for a while now. Universal masking needs to make a comeback. Wear a mask any time you're indoors that's not your home.

More on the CDC analysis. "It cites a combination of recently obtained, still-unpublished data from outbreak investigations and outside studies showing that vaccinated individuals infected with delta may be able to transmit the virus as easily as those who are unvaccinated. Vaccinated people infected with delta have measurable viral loads similar to those who are unvaccinated and infected with the variant.
“I finished reading it significantly more concerned than when I began,” Robert Wachter, chairman of the Department of Medicine at the University of California at San Francisco, wrote in an email.
CDC scientists were so alarmed by the new research that the agency earlier this week significantly changed guidance for vaccinated people even before making new data public.
Walter A. Orenstein, associate director of the Emory Vaccine Center, said he was struck by data showing that vaccinated people who became infected with delta shed just as much virus as those who were not vaccinated. The slide references an outbreak in Barnstable County, Mass., where vaccinated and unvaccinated people shed nearly identical amounts of virus.
“I think the central issue is that vaccinated people are probably involved to a substantial extent in the transmission of delta,” Jeffrey Shaman, a Columbia University epidemiologist, wrote in an email after reviewing the CDC slides. “In some sense, vaccination is now about personal protection — protecting oneself against severe disease. Herd immunity is not relevant as we are seeing plenty of evidence of repeat and breakthrough infections.”"

Commentary: The perspective that Delta is in some ways a new virus is correct. The good news is that the data still shows vaccines are 90%+ effective at preventing hospitalization or death. But we know COVID-19 leaves a wide trail of problems, so do yourself a favor: mask up.

A reminder of the simple daily habits we should all be taking.
1. Wear the best mask available to you when you'll be around other people, even after you've been vaccinated. Respirators are back in stock at online retailers, too. Wear an N95/FFP2/KN95 that's NIOSH-approved or better mask if you can obtain it. If you can't get an N95 mask, wear a surgical mask with a cloth mask over it.
2. Verify your mask's NIOSH certification here: https://www.cdc.gov/niosh/npptl/usernotices/counterfeitResp.html
3. Get vaccinated as soon as you're able to, and fulfill the full vaccine regimen. Remember that you are not vaccinated until everyone you live with is vaccinated. If you received an adenovirus vaccine (J&J/AstraZeneca), consider getting an mRNA single shot booster (Pfizer/Moderna) if permitted.
4. Wash/sanitize your hands every time you are in or out of your home.
5. Stay out of indoor spaces that aren't your home as much as practical. Minimize your contact with others and avoid indoor places as much as you can; indoor spaces spread the disease through aerosols and distance is less effective at mitigating your risks.
6. Get your personal finances in order now. Cut all unnecessary costs.
7. Replenish your supplies as you use them. Avoid reducing your stores to pre-pandemic levels in case an outbreak causes unexpected supply chain disruptions.
8. Ventilate your home as frequently as weather and circumstances permit, except when you share close airspaces with other residences (like a window less than a meter away from a neighboring window).
9. Masks must fit properly to work. Here's how to properly fit a mask:

A common request I'm asked is who I follow. Here's a public Twitter list of many of the sources I read.
https://twitter.com/i/lists/1260956929205112834
This list is biased by design. It is limited to authors who predominantly post in the English language. It is heavily biased towards individual researchers and away from institutions. It is biased towards those who publish or share research, data, papers, etc. I have made an attempt to follow researchers from different countries, and also to make the list reasonably gender-balanced, because multiple, diverse perspectives on research data are essential.
