The current rate of fatality on reported cases only is 3%.
Enough to crush every healthcare system in the world.
Remember most (all?) of those are in China.
No one in their right minds expect Chinese healthcare to be anything but pure crap.
3% to 6% was the factality ratio of the Spanish Flu. Over 65 million die depending on your source. Wiki has it at 50 to 100 million die from that outbreak.
