Indeed, I don't think the mask mandate does sod all, because vast majority of transmission is at home and people will bring it back to those settings from work/school etc. Not going into it again but it really is a fundamental misunderstanding of how a virus spreads exponentially - you either cut routes of transmission or you don't; there's no middle ground. Masks stop one to one transmission to a degree but not exponential community/home transmission.
I don't think removing restrictions will make it outcompete Delta quicker, because they'll both be subject to the same scenario in terms of transmission opportunity. But what I am saying is that with Delta pretty much flatlining in terms of hospitalisations/deaths without restrictions then it doesn't make sense for any restrictions for a variant that evidence suggests is less lethal.
We’ll agree to disagree on masks and their role in community transmission
This is your comment that gave me that impression on outcompete.
“Rather than restrictions, we should be doing the exact opposite IMO. It's a golden opportunity to see off Delta completely.”
As for ” with Delta pretty much flatlining in terms of hospitalisations/deaths
without restrictions then it doesn't make sense for any restrictions for a variant that evidence suggests is less lethal.”
I think there was a worry that the “booster effect” against Delta was changing even before Omicron which , combined with higher than normal non Covid seasonal pressures, could lead to trouble for the NHS
Add in a worry that South Africa hospital rates (much younger population, lot of natural immunity vs vaccine acquired and some of that from a Beta wave) would not be the same in Uk and Europe.
I honestly don’t know what the right decision was to make, just glad I didn’t have to make it.
FWIW I have high confidence that Omicron is more transmissible via a combination of immune evasion and inherent transmission but very low confidence on what exactly that balance is. Similarly the data from South Africa is encouraging re severity but I don’t know how much of that will be duplicated in UK/Europe/US given the different variables.
Hoping for the best but planning for worse would generally be my approach with such low confidence in data but I appreciate that others can come to different conclusions based on the exact same data.
