This hot take is a dangerous bit of poor math. Neverymind that we don't actually know the data for Omicrom to inform this... 1/ smh.com.au/national/could…
even if it is more transmissible but less virulent, IT WILL STILL KILL MORE PEOPLE because more people get infected. This is the problem with exponential growth. 2/ theconversation.com/coronavirus-va…
but again, we don't know any of this. Avoid the Hopium. Use the precautionary principle until we know better. Then when we know better, do good science based planning. fin/
more math for you mathers

A short thread examining expert advice on airborne transmission in this new @calgaryherald article. 1/ calgaryherald.com/news/local-new…
This whole paragraph is incorrect. Aerosol spread has been shown to be dominant, from well before Nov 2020. In fact, there is no evidence for droplet spread, and minimal evidence for contact. 2/ cdc.gov/coronavirus/20…
Incorrect. The new guidance says: a medical mask or a respirator, not just a medical mask. A respirator (aka N95/KN95/elastomeric) is a much better fitting mask than a surgical mask and will be much better protection when exposed to virus in aerosols. 3/ canada.ca/en/public-heal…

Hey folks, long time no see. 1/
Hey so funny story. On Saturday a new fake twitter account popped up using my name and image. I thought oh, maybe I need to get a verified account now? So applied for one, only to find out I don't qualify (not enough followers they said). 2/
So I reported the new account, and mentioned in the report "by the way, there are multiple fake jvipond accounts". Yest at 4:40 was told my report had been acted on, and the offending account suspended.3/

So, it's time for a long tweet thread on airborne transmission, and the resistance of AHS, AH, and Canadian IPAC (that's Infection Prevention and Control) to acknowledge the problem, and mitigate it, resulting in umpteen preventable illnesses and deaths. 1/
We've known from at least May 2020 (perhaps China recognized it in Jan '20) that COVID was primarily transmitted via airborne means, by inhaled aerosols. However, IPAC has been using an alternate concept known as contact/droplet (c/d). 2/ pnas.org/content/117/26…
As time has gone on, there has been increasing quality and quantity of scientific studies supporting airborne/aerosol transmission. It's quite irrefutable now. 3/
