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 a qualified healthcare provider who knows your specific medical situation over advice from people on the Internet.

"Whether it’s the moviegoer who ditches their mask at the start of the show to eat popcorn and never puts it on again, or the commuter on the subway who sports theirs just below the nose, mask use in Ontario seems to be slipping, literally.
But with COVID-19 cases ticking up again with the cold weather, a reopened economy, and vaccination rates plateauing, Canada’s chief public health officer is urging people to double down on masking as a tool to help stop airborne transmission.
In a series of tweets over the weekend, Dr. Theresa Tam stressed that the virus can linger in the air we breathe, much like second-hand smoke, and a well-fitting mask is vital to protect yourself when spending time in indoor public spaces, particularly in the absence of good ventilation.
There has been a paradigm shift in the thinking behind mask use, to the current emphasis on protecting oneself as opposed to the initial consideration of keeping others safe from what we might be exhaling, said Colin Furness, an infection control epidemiologist at the University of Toronto.
“The game has changed,” he said. “We’re not masking to protect others from our own droplets now, we’re masking to protect ourselves from people who are being lackadaisical and reckless.”
Added family physician and epidemiologist Dr. Jeff Kwong: “We’re all so fixated on the vaccines, and definitely don’t get me wrong, they’re very effective. But I think the masks are just as important as the vaccine.”"

Commentary: This is an important part of the analogy about COVID-19, smoking, and indoor spaces. When you walk into a room where someone has been smoking, how long after they've been smoking does it still smell like smoke? The smell, the smoke doesn't fade away after a minute or five minutes. Sometimes it's HOURS. The only thing that makes that room smell better is ventilating it a lot, for a long time. Cigarette smoke is smoke that has been in someone's lungs, someone's respiratory system - just like COVID-19. Unlike cigarette smoke, you can't see or smell COVID-19, but it's there just as surely as if someone had been in the room smoking.
I strongly agree with Dr. Furness: we are masking to protect ourselves now. Mask up with the best mask available to you, N95/FFP2 or better any place where you'll be breathing air that other people who don't live with you are also breathing. Imagine that everyone outside your home is smoking all the time. What would the air be like in the local mall? The restaurant? The airplane? The office? If you think the air would be smoky, then wear a mask in those places.

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 people you don't live with, 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 and away from people you don't live with 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. Aim to have 3-6 months of living expenses on hand in case the pandemic gives another crazy plot twist to the economy.
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:
10. If you think you may have been exposed to COVID-19, purchase a rapid antigen test. This will detect COVID-19 only when you're contagious, so follow the directions clearly. https://amzn.to/3fLAoor

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.
