I don't know because I am really worried about misinformation. Are we getting accurate numbers from china?
I would guess fewer than deaths from the flu, but it probably matters how well they can keep it contained. The incubation period seems the like the worst part of this. Flu you don't get 14 days to spread it around.
I've been more concerned about this in general than most people. My grandma was peculiarly old since she was 40 when she had my dad. She was born in 1907 and she was a young girl during the Spanish Flu.
So, she said that at that time, everyone stayed inside for the entire winter, meaning November to May. You didn't go to town, and you didn't go to school. In the summer everyone came out of their houses and the threat was mostly over. Still, not everyone came out of their house. She said there were more than a couple houses in her small rural town where everyone inside was dead.
That was pre airtravel and people stayed put then and tens of millions of people died.
What I am concerned about it the death rate is right in the sweet spot for pandemics. If it is higher, it usually burns itself out. That and the incubation period.
Right now, we probably good because the total numbers are so low, but again I am worried about misinformation. The quarantine in Italy failed, and I see the same thing happening here if it happens. People can't afford not to work for a month.
