Another data point about how this isn't the flu:
Italy's health system at limit in virus-struck Lombardy
Quote:
MILAN (AP) — The coronavirus outbreak in northern Italy has so overwhelmed the public health system there that officials are taking extraordinary measures to care for the sick, seeking to bring doctors out of retirement and accelerate graduation dates for nursing students.
Lombardy has a population of 10 million and the health system is overwhelmed with 770 (of the 1700 known infected) requiring hospitalization, and 9% in intensive care. That's a 0.017% infection rate overwhelming hospitals. Even if we assume it's undercounted by 1000% (very unlikely given the extent of testing now including contact testing which are the most likely infected). In the generous 10x undercounting scenario, that's 0.17% population infection rate overwhelming hospitals. What is 1% going to look like? 10% as the flu often reaches? People will die in the streets and at home like they did in Wuhan, and the death rate will go up as a result of no medical care for severe pneumonia. Given this, the only solution to keep the death rate down will be total lockdown, China style (they did it for a reason), which will devastate economies for at least two months.
imo our only hope of avoiding a second Spanish flu and the devastation that caused is that the virus spread is stopped by spring weather starting mid April. Given how incredibly infectious it is (spring only reduces R0 by some amount, it doesn't magically put it to zero), even that might not be enough. But it should improve things.
