Very nice, thank you!

I reply with my humble contribution, based mainly on John Hopkins' data. I tried to understand if the effect of restrictions is already visible (I hope it will... since I live in Milan), thus I fitted an exponential on the data from the week before March 1 (when the initial mild restrictions started) and compared with the actual growth.

The model is quite simplistic, but the decrease seems real. Let's hope a bigger one will happen in the next days.
