If I were paid to do this job, I'd be in the media and on social media every day. I'd say: 1)get vaccinated for covid and the flu. 2) wear a respirator (N95) mask in crowded indoor spaces like public transit. 3) keep your holiday get-togethers safe by keeping things well ventilated and filtered.

Tis the season to be reminded of your family's willingness to accept health risk. And to be forcefully reminded of your difference in risk assessment.

This is a great bluesky thread that runs through the major papers published in 2020 about what we knew then about #covid. Its an impressive list and a major scientific accomplishment. Most of the major risks and issues were at least pointed at in rough by the end of 2020. Not withstanding the […]

Flu hospitalizations nearly double as H3N2 spreads across Canada For the week ending Dec. 13, Canada saw 11,646 new cases of the flu being detected, which means 27.7 per cent of all the tests conducted in the country came out positive.

If you haven't read the latest from @johnsnowproject.bsky.social you really need to. TL;DR SARS2 is a neurotropic vasculitis that suppresses the immune system at a *population level* below baseline, and reinfection makes it worse. Male, >41, post acute symptoms or cardiovascular disease […]

Why the “immunity debt” narrative ultimately collapsed: Over the past few months, the conversation has moved toward the conclusion the evidence has been pointing to for years. Since 2022, immunity debt offered an easy explanation for the unusual patterns of illness we kept seeing. 1/7

Canadian COVID Forecast Jun 28-Jul 11, 2025 ONTARIO HIGH (no change) About 1 in every 118 people infected Compared to lowest point of pandemic in Canada: -Infections ~5X higher -Long COVID ~7X higher -Hospitalizations ~6X higher -Deaths ~5X higher

Modeling flu and Covid out suggests a 0.04% IFR for covid, and also suggests we are still undercounting acute covid deaths to an extent.

We continue to avoid the key lesson of #covid - we have to sanitize our exhaled waste air like we sanitized our food & water waste in the 19th century. Until we centralize air sanitization into HVAC, we won't defeat airborne diseases like covid, flu & RSV. And many others. ASHRAE has given us […]
