When the UK reopened from their fall lockdown (graph), cases were still high & variants were able to surge. The UK went back into lockdown within 3 weeks. Germany is learning from this & not reopening early. Today, the Ontario Science Table shows this is a lesson for us too. 1/7
Their modelling shows by mid- to late-March, Ontario could again be seeing record high daily cases. ICU occupancy would start increasing, before hospitals have even had a chance to get under their capacity threshold. Ontario is staring at another possible lockdown in 1 month. 2/7
To avoid this, we need to lower the reproductive number (R) to the equivalent of 0.7 for the current virus (OV); that equates to 1.0 with the new variant (NV). Ontario currently has a R just under 0.9 in lockdown. That equates to 1.26 with the new variant. Cases would surge. 3/7
That's with status quo. If we lift the lockdown, cases will rise even faster. Our case numbers are dropping, but they are still averaging well above the peak of the first wave. Ontario is primed to repeat the errors of the UK if we don't learn their lesson about reopening. 4/7
We are now in a race to vaccinate before the variants can catch-up. If cases are rising, health workers will be busy treating #COVID19 patients, stopping outbreaks, & contact tracing; they won't be available to vaccinate. And we need to buy more time to get vaccinations done. 5/7
Tomorrow, the province announces at what colour level regions reopen. I hope they are cautious & keep enough measures in place. 6/7
As Angela Merkel said,
"The time between now and the middle of March is when the experts are telling us that the mutated virus could gain the upper hand over the initial strain. It’s crucial that we lower the infection rate in this time period." 7/7
It's a hot topic why I'm not ordering a requirement to wear #masks at this time. To be clear, in alignment with @WHO, @PHAC_GC, & @CPHO_Canada, I absolutely recommend we wear #FaceCoverings when we can't keep 2 m #PhysicalDistancing. Here are 3 reasons why I don't require it: 1/8
1. Enforcement. A public health order requires a court filing and an appearance before a judge every time one wishes to enforce it on a person/business. An order would be basically unenforceable. If we don't enforce, it's effectively just a recommendation (already done that). 2/8
2. Strength of science. While science increasingly supports #facecoverings are likely effective at slowing #COVID19 spread, research is still weak. E.g. @TheLancet systematic review finds much potential benefit, but only “low certainty” that effective. thelancet.com/journals/lance… 3/8
