“Parts of Italy were in lockdown prior to March 1, so for those areas they are in lockdown day 21+.”
To be fair, Wuhan is still locked down. That probably is the explanation for there being less than 20% of the normal traffic volume. Or they are all dead, welded into their apartments (does starvation count as an underlying condition?)
RE: Italy/Wuhan.
Lombardy is full of Hubei born workers in the garment industry.
They went home for New Year, and at other times to visit family.
And came back.
And brought the virus to Italy long before Italy was aware.
The fight in Wuhan against the virus began long before the fight in Lombardy.
But both outbreaks likely started at the same time.
