Use of care and mortality due to corona/Covid-19 in Finland, Sweden, Norway, Denmark, Iceland, Estonia; data from 25.6.

+ Excess mortality + Apple.

Thread. (English version).

Fig 1a-b. Number of persons in intensive and hospital care per day. 1/x

Fig 2a-c. Number of deaths per day (moving average) and cumulative mortality. 2/x

Fig 3a-c. Geographical differences within Finland: Nr of persons in care/day and nr daily verified diagnoses by the five “specialised medical care regions”. 3/x

Fig 4a-c: Finland: Weekly total mortality by sex and age early 2020 until week 22 and previous years. 4a, I marked years 2010 (hot summer weeks) and 2018 (severe influenza season) as the effects can be seen clearly (summer 2018 might have been hot as well?) 4/x

Fig 5. Weekly total mortality in different countries early 2020 as compared to previous years + Extras: Sweden and Denmark by sex and age.

For Sweden I included the previous years also separately, and marked the severe influenza year 2018 for perspective. 5/x

Mortality in Sweden almost back to historical normal levels already here week 22 (end of May) in all age groups.

Interesting article about local excess mortality within countries in Europe: 6/x

Fig 6a-c: Apple’s Maps-app, mobility index; routing requests for transit, driving and walking in Helsinki, Stockholm, Oslo and Copenhagen (base 100 at 13.1.2020).

Mid-summer festivities (17-21.6) can be seen in these clearly for Helsinki and Stockholm. 7/x

Use of mobile apps to track and trace was discussed a lot in the early days, but so far the evidence of their impact seems limited. Finland will have an app but it is still in development. 8/x

In Iceland, almost 40% of the population had installed the app already in May, but most tracing was still done by traditional methods (phone): 9/x

I think these could be important for the future; the situation is far from over and experiences around the world demonstrate that initial good experiences might be temporary and things can escalate quickly: 10/x

At the same time, it might be difficult / impossible / unacceptable to have digital tracing system in the nordic countries similar to what is in use for example in South Korea: 11/11
