Some people don't seem to understand why lockdowns happened.
They did because cases and deaths were rising fast.
Some lockdowns were stricter than others. Because health care systems were already failing in some cases.
Sweden didn't feel the need to lockdown because they felt they could control the epidemic without full lockdown, although they implemented control measures. It wasn't too bad, but they didn't consider it successful on the whole, due to the number of people who died then.
Right now, everyone has learned a lot more about the virus. Case fatality rates are lower everywhere, but in some regions hospitals are getting to capacity again.
(Because many people thought it was over? - from MN pps shouting about how empty hospitals were
)
There should be more testing and tracing capacity now, and more protective equipment for everyone. We should know the behaviours and conditions that are riskier and those that are safer.
It shouldn't be about blindly following any rules of 6, or whatever.
Ideally, countries shouldn't have to lock up. Realistically, and unfortunately, some countries, or some regions may have to. Because they are not Sweden, and they will do a lot worse than Sweden with the same measures.
And, again, Sweden is at the start of another (smaller or larger) wave. They will figure out what's best for them as the number evolve.
It's rather silly to claim they are doing very well before we see how their numbers progress and until they go down.
