Iceland and a couple European countries did some sample testing studies where they tested a random sample of the population(1-2 %) to see how many people have coronavirus antibodies. Even in Italy in the most affected regions this was only about 10%, on Iceland it was about 1%. So it's really unlikely large amount of the population anywhere has already had the coronavirus and might be immune without anyone noticing (without you know, all the totally overloaded hospitals and lots of people suddenly dying).
