We are at a precipice. The World Health Organization has declared clean indoor air a fundamental human right, and ventilation is a key component of ensuring clean indoor air. The current standards governing our ventilation rates are not based on health and have not been for decades. There does seem to be alignment forming on health-focused ventilation targets. A group of more than 40 international experts wrote a commentary in Science in March 2024 proposing indoor air quality standards, wherein they recommended … 30 cfm/p17; the same target recommended by The Lancet COVID-19 Commission,13 and the same health-focused ventilation target used 100 years ago. The lessons from our past combined with recent experiences present an unambiguous call to action: to recommit to ventilation not as a technical standard for minimally acceptable conditions but as a cornerstone of public health.

New large study finds COVID may increase risk of heart attacks and strokes three years after infection. Unlike other infections, the elevated heart risks from infection did not appear to diminish over time, a striking finding that the researchers say is "unique to COVID."

For those wondering why our COVID Forecast score is so high for months on end. It predicts % excess mortality, based on excess mortality estimates from Statistics Canada. If you doubt @StatCan_eng excess mortality estimates, here are the estimates for Canada, the UK and United States from @OurWorldInData . Since the start of Omicron excess mortality in Canada has fluctuated between 10 and 35%. That's higher than StatsCan. We're doing considerably worse than the UK and US, and have been for quite a while. But we don't talk about it publicly.

Covid and increased risk of major adverse cardiovascular events (MACE) 3-years out ahajournals.org/doi/10.1161/AT… 2-fold increased for any severity of Covid ~4-fold increase for Covid requiring hospitalization "a coronary artery disease equivalent" interaction with non-O blood types @uk_biobank

"A major finding from our analyses was that the risk of MACE among the subset of hospitalized COVID- 19 cases without known CVD (ie, primary prevention patients) was comparable to (or even slightly higher than) the risk in patients with CVD, PAD, or diabetes but without COVID-19."

Thanks TVO for covering covid in the Agenda, it was fabulous in the studio - great guests with interesting perspectives - look forward to seeing it air. Great job…

Unfortunately I’ve had people tell me that some public health depts have advised those waking up with a bat in the room they do not need rabies shots if they don’t have a bite or scratch. This is untrue, & while <15% of bats have rabies, it is 100% fatal. brantfordexpositor.ca/news/local-new…
