No, I don't think so. I think we will have test, track and isolate to help suppress spikes.
Here most people are still acting completely appropriately, you don't need 100% for a lockdown to work. Most people are still abiding by rules.
Where can people now go that they couldn't before? The garden centre? Stay outside a bit longer? Those are really low risk activities. People that can work from home should still be wfh and those who can't could work before anyway. I don't think tonnes of people have suddenly resumed working in unsafe ways.
We will probably see a slight rise and then fall again as in other places.
I do think face masks should be mandatory in all shops and on public transport, I cannot see why this hasn't been done. It is that that will cause a rise potentially, and something so easy to implement.
schools have been open the whole time and some have been very busy (NHS nurseries) with only a few confirmed cases in teachers (that may have been picked up from family or the community, without tracing who knows?) so I don't think schools phased opening will cause a spike.
We will have to live in the 1.5 / 2M economy for the long term and you won't be able to hug anyone any time soon. Not sure how that works for people dating... birth rate will drop at some stage I imagine!
