> Probably not. Case fatality rates don't accurately show the "deadliness" since many people have likely been infected but been asymptomatic or had mild illness that didn't cause them to seek medical advice.

I agree with this point but would also like to point out the possibility that way more people get infected by SARS-CoV-2 than the flu.

I also want to note that the flu also has the same asymptomatic or mild illness factor and that the deadliness would be only comparing people who sought medical treatment.
