Sweden's got 10m people, and 87k cases as of mid-Aug. That's less than 1%, so claiming "herd immunity" is BS. They also have almost 6k deaths. Analysis from a month ago projects Sweden's GDP falling 4.8% in 2020, and eyes a 3.6% growth in 2021 - overall down 1.4% across both years. Denmark's got a little over half the population, 1/5 the cases, 1/9 the deaths. Projected GDP is down 5.1% this year, up 4.0% next year,…
We don't know the real herd immunity threshold. It had been previously estimated at about 70%. However daily average deaths in Sweden are now down near zero even though there are minimal pandemic control measures, and seroprevalence studies have indicated an exposure rate probably below 20%. So what accounts for the current situation? https://www.worldometers.info/coronavirus/country/sweden/
The 20% antibody threshold seems to be fairly common across many countries however, at least outside non-China Asia/Pacific countries that were not badly affected at all. The body learns how to fight viruses and can do so quite quickly.
