That thinking will mislead you. C19 has a much higher rate of contagion, which is why people are trying to bottle it up fast. China, Italy, and Iran did not shut down to contain influenza in any year, no matter how bad the flu was. That is not accidental, not mere panic.
I know even the president is doing it, but you have to remember to watch what he does, not what he says, because he just says stuff all the time. Bird Flu, Swine Flu, they're all different, with different rates of contagion and deaths per thousand cases.
