Study is here: https://www.medrxiv.org/content/10.1101/2020.05.25.20113050v1 … IFR for the whole state is a bit lower - using the same date cutoff, it is ~0.84% with 14% infected

2 - Brazil An impressive effort from Brazil, nationwide seroprevalence sampling. The authors report a corrected IFR of 1% https://www.medrxiv.org/content/10.1101/2020.05.30.20117531v1 …pic.twitter.com/bcT4vTzRv7

What's particularly interesting about the Brazilian study is that the IFR range is given, with places reporting between 0% and 2.4%

3 - London While the testing hasn't been published formally, the estimates appear to be that 17% of the city had antibodies mid-May So, cumulative incidence of ~1.5million people by 13thhttps://www.thelancet.com/journals/lanres/article/PIIS2213-2600(20)30247-2/fulltext#coronavirus-linkback-header …

Now, extracting an IFR from these figures is a bit of a headache, because England only publishes specific information on COVID-19 deaths in hospitals, but the deaths appear to be 5,644 on this date from that source

Given that ~75% of London COVID-19 deaths occur in hospitals, that means ~7,500 deaths and ~1.5mil cases, so an IFR of ~0.5% for London

We can also look at the whole UK IFR from this data ~5% of the country infected gives ~3,332,500 infections 24,000 deaths in-hospital gives ~32,000 deaths Therefore overall IFR is 32k/3.3mil = 0.96% IFR

(Apologies, above tweet should say IFR for the whole of ENGLAND, not the UK. This data is from the ONS testing in England, and the death reports from England as well)

This is using death data from the 30th of April to again crudely account for right-censoring

Another new estimate - the authors of the Geneva seroprevalence study have age-corrected their data and come to an IFR of 0.64%https://www.medrxiv.org/content/10.1101/2020.06.10.20127423v1 …

Second stage of Indiana serology testing has come back, implying 1.5% of the population had been infected (and 0.6% was currently infected) with COVID-19 by 8th June That's 2.1% of 6,732,000 people, or 141,000 infectionspic.twitter.com/Ejq4MmA7Kf

With 2,413 deaths in Indiana by 13th of June, this implies an infection-fatality rate of 2413/141000 = 1.7% (VERY high)
