I regret taking this bait....but the flu kills tons of people every year because we barely do anything to prevent exposure to it Everyone gets it, people die just due to the sheer numbers despite the low fatality rate. This virus is upwards of 10x more deadly and spreads much more easily based off of current estimates.
I, and most people, have nothing to worry about. This does not mean we should go around like nothing is happening just spreading it to everyone on earth at the same time. People already go to the hospital for the regular flu. If left unchecked, COVID19 will spread to many more people at once, and a much higher proportion will go to the hospital. This will overwhelm our capacity to treat patients, and will cause more deaths than necessary.
This is much different than people dying because of their own health related issues due to eating big macs every day. They largely did that to themselves. Us treating this virus as if it is nothing would be us harming others through negligence. I cant stop you from eating yourself to death, but I can stop myself from infecting you.
