Quite possible, there were rumors of a new flew in Wuhan since September. Like actual people testing for any influenza but had flu-like symptoms.  So if what you say above is true, 45 days before Mid September would be August. If your saying 3 times exponentially worse, then quarantine isnt to stop the spread. It's to hide what's going on and clean up all the dead. Probably why the WHO doctors will not visit the Province the Wuhan is in, Hubai. They are not allowed. Either way, it's time to chill out, ride this till the end days.
