I hesitate to compare to flu because few people get the flu, relative to the potential reach of CVid 19, thanks to the flu vaccine.
We have 12-18 mos to wait for vaccine here.
Simulation run by WHO indicate 65 million dead which at 2% mortality is nearly 50% rate of infection. 3.25 billion people infected. That’s ginormous.
20% require hospitalization. There isn’t capacity for that.
