We seem to imagine that this is a situation we are in control of, but as a PP said it's more like a natural disaster.
If numbers creep up, and then start to really increase (as we were seeing in March) and their experts are telling the government that either we take drastic measures to cut transmission rates or they expect that in 4-5 weeks A&E departments will be turning people away (whether they have covid or not), most schools are not expected to have sufficient staff to remain open, and the body count will start to rocket - do you really think the government will have a choice? (this is not a prediction but it is one of the possibilities for how this goes).
For those who really do believe it's impossible, how do you think a scenario where we let the virus rapidly run through the population plays out? I think it's a very grim picture.
With Test & Trace and local lockdowns I really really hope they keep a lid on things, but just as I have no idea what will be happening in 3 months time nor does anyone else, so to say that another lockdown is out of the question is naive.
We don't control the virus, we can't wish it away or pretend it doesn't exist.
It's also very disingenuous to claim that anyone wants another lockdown, I found it hard the first time and my MH took a knock last week when we started to see local increases. I have DC and I can't wait to be able to do normal things with them without queuing, restrictions, masks, and the general 'oddness'.
