I'd assume with a very high positivity rate + harder access to testing + inherent mildness = much more cases being missed in developed countries compared to previous waves. It was 1 in 3, but it's possible that now we're picking up 1 in 6 or less.
Of course, that varies from country to country. Somewhere like Denmark or Iceland where maybe two-thirds of cases were being detected might be now at one-third instead, still a respectable number.
Also we're flying on the blind around here because some states haven't reported cases in nearly two weeks because of hacking or some other excuse and we can't really base it off hospitalizations since there's a huge flu outbreak about too. Recent random sampling found out a third of December cases were Omicron around the country, two thirds in Sao Paulo, but who knows for sure. Argentina and now Uruguay are certainly in the thick of it.
