It's really hard to say.
I'm in Korea and we never had a lockdown here. Of course, we were basically the second country to have a big outbreak but the government got right out in front of it with rigorous testing and tracking - every day there are updates of where new patients have been so that you can go and be tested if you were near them. They trace their actions by credit card (couldn't happen in the west, privacy laws). Everyone can be tested, there are drive through places everywhere. It costs about 70 pounds or free if you get a note from the doctor.
There was a big outbreak in Daegu after a woman from a cult spread it around and there was so much negative outcry around her that I think it made people very conscious of not being like her - Korea is a very shame based culture and no one wants to be the wanker that infected hundreds of people. So as soon as they have symptoms most people will go and get tested and isolate themselves.
There is also strict quarantining at the airport and everyone arriving must isolate for 14 days.
Most places are still open, but you have to get your temperature taken and write your details down so that if there is an outbreak they can contact you.
Schools and universities are still closed and many people are working from home but many have gone back to work too.
We are reminded to social distance but tbh I see most people not doing so. Kids out playing daily, underground is full, people in restaurants...
Whether this is working or not remains to be seen but so far we're down to around 30 new cases a day in the whole country and there has only been a single death in Seoul this whole time - for a city of 10 million people who are absolutely crammed in, this is pretty astonishing. The fact that healthcare is far superior here when compared to the UK which has also had an impact. But generally I think the aggressive testing and tracking has worked pretty well.
personally I'd rather see a stricter lockdown because it is a little scary to see people acting so normally when friends and family back in the UK are living under such strict rules but so far there have been no new outbreaks so 🤷♀️
