I'm in New England and I'm happy with what my state government has done, despite the federal government having been so shit.
The goal has been to keep infection rates low, not necessarily to eliminate Covid completely.
The lower the rates are, the more people can go back to working, socialising carefully, etc, knowing that as soon as rates go back up again, then we start reducing opportunities for people to mix.
We locked down around March 13th including closing schools and everyone working from home as much as possible.
Schools are now back half time. Each day half the students are at home learning online and the other half are at school. That makes social distancing possible, plus everyone is wearing masks in school, so we've had no huge spike in viruses such as colds, and so no huge spike in tests.
If the rates in a particular county go up then the schools in that area switch to fully online until rates go down again.
Things like sports, recreation programs etc are being run cautiously, but again are put on hold when rates in certain counties go up.
We've been requiring people to wear masks in indoor public spaces for months now - that's helped keep the rates of infection low.
After international travel or travel outside a small group of safe states you must quarantine until you have a negative Covid test.
Limiting indoor interaction with other people.
Restaurants - you can eat with others from your household, and your table is 6' away from the next table. You wear masks while walking about restaurants. Servers wear masks. All helped keep infection rates low.
Bars are not open. You can get alcohol with meals, table service only. That restricts how much alcohol people tend to drink in one restaurant visit, meaning you don't end up with drunk people losing inhibitions and spreading infection.
People give a name and phone number when they arrive in restaurants, hairdressers, etc. We have effective contact tracing.
Universities generally have reopened only to one or two years, not all years at once. Almost all teaching is online. Testing at least once a week for all students. Space for them to quarantine. Very limited opportunities for students to socialize other than online.
We rapidly opened up as many labs as possible for testing, and developed tests that we could do in-state. Idexx labs (a company that usually focuses on animal health) has been a huge part of this.
Overall the goal has been to keep infections low enough that we don't have to go back into full lockdown.
People tend to comply because they've seen that the economy can only successfully reopen when infection rates are low, so it's in their interests to wear masks, avoid socialising, stay 6' apart, etc.
The other thing is that we only stopped non-Covid medical care for a while, and moved as much as possible to telehealth during that time, so that it was able to resume fairly quickly.
Dentists reopened several months ago now, and my friends who work in things like cancer treatment reduced their service by 50% briefly then resumed full levels of care.
They're also working proactively to get as many flu shots done as possible, as safely as possible, to reduce the load on hospitals if/when Covid rates go back up.
Looking at the UK from the outside, it just seems weird that you went from full lockdown to almost fully back to normal so quickly. Schools with no social distancing or masks seems bizarre - what is the magic that stops schools from spreading infection? University students all going back at once - seems incredibly risky. Pubs open - sorry, utterly mad. People coming back from international holidays and not having to quarantine until they get a negative test - seems strange.
It seems like in the UK everyone is busy trying to blame others for the increase in cases, but everything will be contributing. And it seems like people think it's a binary choice - fully open, or fully locked down - when in fact there are many in-between options.
