I've been thinking a lot about this op as there is a chance the next 2 months are going to be very bad indeed (I really hope not!) and I wonder if we'll look back and regret not taking much more drastic action
My theory is that
a) we're just too late for any lockdown. So many people are being infected each day that there is literally just no point. I think even if we locked down today and hard, every infected person will just infect people in their homes or travelling to shops etc. It's going to make absolutely no difference
b) You can only lockdown a population that wants to be locked down. How else do you enforce something like that beyond getting the army out, fining people, imprisoning people etc? People would be horrified (understatement!) by that kind of action and rightly so. There is no appetite for a lockdown. The government are waiting for that to change, which it will if deaths skyrocket. People then lock themselves down, essentially. If deaths don't skyrocket, there's no real need for a lockdown anyway so it's ok.
c) there are other strategies beyond lockdown - one being pushing hard to get vaccination levels as high as possible, which is the one the government is going for. The population is getting vaccinated in really large numbers, thank goodness, and that is going to help more than anything, even if we do end up with high death rates before the effects of the boosters kick in properly (because it takes 2-3 weeks for immunity to develop). We might have to wait to see it make a difference but give it 4 weeks and Omicron will be slowed down and run out of people to infect or kill
I hope you're ok OP and getting some support. This is really scary isn't it? I hope things will be manageable, there is lots of reason to think we will be ok. If things are dreadful, this wave should be short and sharp just because of how quickly it's moving so by February/March, things will be significantly easier. I'm going to be keeping myself as busy as I can until then!
