That unvaccinated people are higher risk of getting and spreading Covid? I agree, although I'm not sure what is the significance of the 4:1 ratio. Ontario's numbers suggest a risk ratio closer to 7:1 or 8:1 right now.
The breakdown is similar on weekends, holidays, etc which suggests that mandatory testing does not skew the numbers significantly in Ontario at least.
But as I said: reported cases blah blah, they paint a fairly clear picture to me but there is a lot of complexity there.
What about ICU numbers?
