My impressions fully overlap with what David said.
Here in Bulgaria we're a very interesting case because we're a former Eastern Bloc country where people tend to disobey everything. Take in mind we've been in a so called "political crisis" (basically parties hate each other and accuse each other of all the evil on earth and they can't agree to form a government for three consecutive parliaments this year), and so since there were also some public protests related to the political situation during the lockdown, the government didn't enforce any real measures because that would mean even more protesters who will pretend that the government wants to silence them under the pretext of Covid... 🤣 Also, there were concert halls, theaters, etc. open at 1/3 capacity all the time.
Anyway, long story short, Bulgarian people are this kind of pricks who just ignore rules and do what they please and almost nobody wears masks, we have the lowest vaccination rates in the EU (20%). As a result of all that many people here got Covid at some point, almost everybody I know got it sooner or later and I have some personal statistical observations which are ultimately similar to what David mentions.
Most people would go through it easily. Only a small percentage would get hospitalized. And then a small percentage of those unfortunately die... I know only two people who died (a neighbor who was old and had a heart surgery some years ago, and our the elevator-repair guy in our building who was also old and in bad health). My mom who is 74 was in hospital in November due to Covid but it wasn't really serious. In February we all got infected with Covid: me, my wife, our kid, the mother and father in law. The father in law has been having problems with his heart for years, so he got in hospital for a week but again nothing serious, whereas the mother in law had no symptoms at all, only a positive PCR test. I was for 5 days in the bed, really exhausted, like a nasty flu.
I have a friend who is my age, fit and strong, eats healthy, etc. who was for three weeks in hospital though. It's a bit of a Russian roulette, not sure what it depends on.
