1/x Covid - Europe: The 2nd Wave collapse continutes
We continue with daily overview using JHU data (+some) looking at 'fast' weekly changes (day over the same day the prev. week) this gives us an edge in being up-to-date.
2/x Changes in weekly growth rates reflect changes in R's, thus these charts roughly represent changes in R's. Now let's see for particular countries .... but overall looking at the continent gives us a 'situational awareness' since this is like a savanah fire ....
3/ Czechia and Belgium were 'second wave Lombardia' they are doing particularly well. In fact that's due to e.g. Czechia having 2,5% population officially infected in 5 weeks, with their dark probably some 25% - it had to stop.
4/ We have a nice illustration how Czechia chickened out with a needless lockdown (blue point) when the rates were already falling ... it 'might' start working just about now (10 days after intro), whereas the rates have already been negative for some time ....
5/x Some more countries from the north:
6/x Lockdown might or might not have worked for Ireland, the situation would have been the same:
7/x Turning to the south:
8/x Germany chickened out needlessly, there is a lockdown, but this development is not (yet) attributable to it:
9/x A said story called UK, Switzerland is also doing fine:
10/x Proud to be Croatian this time, our prime minister has just said we will not 'fall for a lockdown or curfew TRAP', he didn't chichen out. BTW Slovenia doing fine, much earlier then potential lockdown effects:
11/11 And there are some countries which haven't joined the movement as yet ....

1/ Now REALLY interesting results from Sweden. After current infection rate at ~0% published on Thu, yesterday seroprevalence in a Stockholm district in June (related to infection prevalence beg. of June) showed 18.7% AB. Allowing for addtl. 3 mo. buildup, probably ~25% now ...
2/ ... leading to countrywide prevalence od probably at least 15% (having in mind Stockholm is big and there are some other big cities). Karolinska research found out 2/3 infected did not develop measurable AB, meaning 40% country-wide infection has been reached ....
3/ ... and infection collapsed, as predicted by models using (naturally!) heterogenity. For sure reaching HIT does not mean the infections stops, just it slows down to a weak propagation, together with potential smaller local outbrakes.
1/ Calling @IHME_UW to correct GIGO model for Croatia which, using wrong inputs and unclear algorithms produces ludicrous projections and compromises trust in the integritiy of the whole project @MLevitt_NP2013
2/ The model anticipates 1500 COVID victims in Croatia by 1-10-2020, the current no. being 108. That's 14 times more. Comparison with neighb. Serbia and BiH really puzzles, projected deaths/m. being 11 and 5 times higher though the current situation is inverse, especially trends
3/ The model itself screems 'unreliable' adding 1500 'expected' victims from the last 'observed' data and the 95% interval between 0 (!) and some 17,000 (!) cases growth. The latest seroprevelence figures by the gvt. are in the 2% zone, implying IFR of some 0.125% ...
