Back to numbers:
2019/2020 US flu season numbers to date: 20,000 deaths in 34,000,000 cases = 0.06% fatality rate
As of right this instant, latest US coronavirus numbers I've seen are 21 deaths in 550 cases = 3.8%.
Say it's going to decrease by a factor of 4, so it's "only" 0.95%. That would make it 0.95/0.06 = 16x as deadly as this year's flu.
1) That factor of 4 is pulling a number out of the air, but it would still make coronavirus a LOT more dangerous than this year's flu season.
2) The current worldwide numbers (3800 deaths over 108,000 cases) are running at a bit over 3.5% fatality rate, IOW 58x as deadly as this years flu numbers for the US.
As of right now, based on the actual numbers, coronavirus is over 50x as dangerous as this year's US flu season.
The sky isn't falling, but given the current actual numbers this isn't a trivial matter. If 34m Americans fell ill with covid-19 (that's how many have had the flu so far this season), based on the current fatality rate it would be over 1 million deaths. An even bigger thing is the health system right now isn't set up to handle that many extremely sick people - not enough ventilators, not enough isolation capability, not enough...
Even with relatively large numbers of people getting flu shots each year, we've had 20000 deaths so far this season. There is no coronavirus vaccine, won't be for another year at best. A flu shot, while good to get, does not protect you from covid-19.
