Stephen Fry says Sweden's streets are 70% less busy and it's not dodging economic fallout

26. Sweden is hoping for herd immunity in the Stockholm area in May. We'll see.

From an article today:

How Close Is Sweden to Herd Immunity From the Coronavirus?

Sweden is not doing well. By April 22, its mortality rates from COVID-19 were the tenth highest in the world, with 17.3 deaths per 100,000. By comparison, its neighbours Denmark, Norway and Finland ranked 17th, 22nd and 31st, with 6.4, 3.4 and 2.6 deaths per 100,000.

How close Sweden is to herd immunity is unknown, because random seroprevalence testing, which requires testing for both the virus and antibodies (to detect past infection), has not yet been undertaken nationwide, although plans are afoot. Nevertheless, the national public health agency, Folkhälsomyndigheten, and Swedish military sampled 738 Stockholmers and found that 2.5% were infected between March 26 and April 3 with SARS-CoV-2.Assuming a case fatality rate of ~0.36% and combining this with confirmed COVID-19 deaths in Sweden (2,021 on April 23), one can very crudely estimate the total number infected through mid-April – by no means a surrogate for expert modelling or direct testing. Nevertheless, this equates to 561,389 infections nationwide (~5.5% of the total population).

Given more than half the deaths have so far occurred in Stockholm (1,128 as of April 23), yet only ~10% of the population lives there, about a third of the population in Sweden’s capital may have been infected by mid-April. This is compatible with the early-May estimates reported for Stockholm by Folkhälsomyndigheten.

It is impossible to know for sure how many people have had COVID-19 – in Sweden and most other countries. But if the simulations conducted in Sweden are correct, and post-infection immunity is achieved in most people, we should soon expect infections and deaths in Stockholm to drop substantially in the coming weeks.
