There have now been ten times as many COVID-19 deaths in Sweden than Norway on a per capita basis.
According to the Worldometers website, 435 out of every one million Swedes have died from the virus, while the virus has killed 44 out of every million Norwegians.
Particularly troublesome is this:
Quote:
Swedish government officials said lockdowns could do little to save lives over the long term and that their more lax approach would let their society reach herd immunity more quickly and lessen the economic pain the country would endure. "About 30 percent of people in Stockholm have reached a level of immunity," Karin Ulrika Olofsdotter, the Swedish ambassador to the United States, told NPR on April 26. "We could reach herd immunity in the capital as early as next month."
But a recent study found that just 7.3 percent of Stockholm residents tested positive for coronavirus antibodies at the end of April. "I think herd immunity is a long way off, if we ever reach it," Bjorn Olsen, professor of infectious medicine at Uppsala University, told Reuters.
I don't understand why the earlier result was 30% and the later result was coming in at 7.3. Possibly one test was identifying IgM and the other was identifying IgG. Maybe the first test had a high false positive.
But, if we think about timelines...
Disease timeline...
Day 0 exposure
After about a week symptoms develop
Antibodies ramp up about 2 weeks after symptoms and top out about 3 weeks after onset.
So, if a positive antibody test is late April, you are actually looking back to early April for exposure. Sweden had fewer than 500 deaths as of April 7 and less than 200 on April 1.
Should we really be surprised that only 7.3% of Stockholm was infected in early April as the disease was just starting to take off?
By April 21, they had over 1500 deaths. with a rough tripling from Apr 7 to Apr 21, you could assume 3x exposure two weeks later. That may show up as 21% antibodies in mid May.
They crossed 3000 deaths 2 weeks later... another doubling to 40% antibodies by late May?
2 more weeks and they cross 4000 deaths, another 1000 deaths and maybe another 15% infected. Do you see 55% antibodies in mid June?
