The Flu mortality rate is a case fatality rate which means it's based on number of deaths divided by number of positive flu tests. Although flu tests are readily available, people with mild flu symptoms don't get tested most of the time and there are asymptomatic flu cases. On the other hand, people with mild symptoms of Covid are getting tested currently and even some asymptomatic people are getting tested when their contacts test positive. As a result, it seems like a reasonable comparison to compare current CFR of Covid against the CFR of Flu. If you do that the mortality difference looks closer to about 20X rather than 7X. The only group that seems to not have an elevated risk of death with covid relative to flu are children, who are not at all immune to the effects of covid but develop serious disease infrequently.
