As a follow up to my previous comment, here’s a really amazing Twitter thread breaking down the situation in France: https://twitter.com/jeuasommenulle/status/1320682084973858816 (threadreader version: https://threadreaderapp.com/thread/1320682084973858816.html)
The poster also tries to estimate R0 using hospital data(which should be more reliable than case data, since the Spring wave was so undertested). He finds a R0 of 1.2, which means a doubling every 20 days.
He estimates ICU usage levels will be as high as the spring peak in France within 25 days, if the trends stay correlated with the spring outbreak.
Lots more nice graphs in the thread too.
I think he just meant the curves would match, ie. referring to the peak from the previous wave: https://twitter.com/jeuasommenulle/status/1320682552257089538
Oh actually, I think he just means they’d get back to that peak level in 25 days, not that it would get better after that. I misunderstood what he was saying. I’ll correct my post above.
