This chart is an interesting case of "how bad is it" and "how well do we know how bad it is?"
https://ourworldindata.org/grapher/covi ... untry=~USAUK, UAE, and Cyprus have a lot of cases per population, but the amount of testing gives confidence they know how bad it is.
Paraguay, South Africa, Costa Rica, Tunisia, Nambia, and Colombia have it bad, but they are not testing enough to know how bad.
Guatemala, Indonesia, Mexico, Bangladesh, Nepal, and Zambia aren't testing enough to know how bad it is, but it could be really bad.
Sadly, it is just too obvious another bad wave is hitting the world.
Note: I believe in metrics.
More than 100cases per million, in particular with Delta, risks having the hospitals over-run.
I consider 10% positivity the upper bound of quantifying the problem. Once more than 20% of tests are positive, that means too many sick people are not being tested and thus not counted.
Of course such simple metrics miss when people are denied testing by cost or location (e.g., is a testing center just too far away?).
I also follow hospitalizations, but that of course is a trailing indicator to measured cases by a few weeks which trails infections by a week or two.
