🆕 New study across 4 Nordic nations “Compared with myocarditis associated with covid-19 disease and conventional myocarditis, myocarditis after vaccination with SARS-CoV-2 mRNA vaccines was associated with better clinical outcomes within 90 days of admission to hospital.”

New study out comparing myocarditis due to Covid-19 vaccines vs infections in a Nordic cohort. Confirming past evidence, there was a higher risk of heart failure and death for myocarditis post Covid-19 infections compared to post vaccination. 1/n dx.doi.org/10.1136/bmjmed

13/ So, the bottom line is that contrary to this new headline, there is in fact plenty of evidence that masks prevent transmission of COVID despite the limited RCT data. And aside from inconvenience, the downside is pretty minimal. So #MaskUp #WearAMask

#COVIDisAirborne If you don't wear a respirator during some of your exposure time, you might as well not wear a respirator at all. The infectious dose for SARS-CoV-2 is very low. It only takes one short exposure to be infected.

We have to talk about this Cochrane review of masking and handwashing that found “little to no evidence” masks (surgical & N95) reduce viral infections at the population level and some evidence that handwashing may help. Let’s dive in to understand why 1/ cochranelibrary.com/cdsr/doi/10.10

Masks work. But humans don't. Does that ="masks aren't effective at the community level" - probably. And also IMO, it's not about everyone wearing them or they don't work, it's about wearing them when risk is present. Which is difficult because that's often & not always obvious.

This is the key point to note about the "masks do/don't work" debate IMO. If you're not masking _whenever_ there's risk, masks are less likely to be helpful overall. They don't work in your pocket or sitting on the kitchen bench when your newly infected school child comes home.

@JenniferNuzzo

For example, if healthcare workers don’t wear masks socially outside work or in the breakroom it can undermine the estimate of overall effectiveness of their masking at work. It doesn't necessarily mean masks don't help protect individuals when they're seeing patients. 16/

Evidence of effectiveness at the population level is not the same as evidence in individuals or in laboratories. At the population level, compliance is a key variable that may reduce the effectiveness of masks. 15/
