For the death rate to rise, a lot of people have to get infected and die. Keep in mind there are a lot of deaths from everything else, so for the corona virus to bring that overall death rate number up in any meaningful way, it would have to be huge.
death rate (mortality) of the total pouplation is around 1-2%/year. Yeah, the coronavirus would have to be huge to increase that - but what is your evidence that it's not being able to get as huge?
