I will agree that the 20 times higher death rate is probably a ploy to make it seem worse than it actually is (it uses the week which had the greatest recorded number of Covid-19 deaths so far), yet the point is, that there is actually no good way to reliably compare the two diseases mortality rates at this time. Added to that, there is much debate as to the reliability of the reported Covid-19 numbers. Some people think they are over-counted, while others believe they are actually under-counted.
Here are some points to consider. First there is no similar system in place for actually counting Flu deaths. Reporting and tabulating those deaths is not mandated. Second, since there are vaccines for the Flu, and none for Covid-19, there are medical means of reducing deaths from the former, but as yet, none for the latter. Another issue is that people want to compare seasonal or yearly estimates of Flu deaths with the current total of Covid-19 deaths. However, the first recorded Covid-19 death in the USA, was only about 4-5 months ago, in January, when we recorded only a handful of deaths. Currently, the Covid-19 death count is still well over 1000 per week, nation-wide. And since we only reached the peak deaths number a few weeks back in April, we will probably have at least another 50,000 to add to the current 85,000 already counted, before this current wave is over.
Bottom line, is that no one can really provide a reliable handle on how these two diseases really compare in their mortality rates. Probably the best measure is the number of "excess deaths" due to natural causes for similar periods before and after Covid-19 came on the scene, Those numbers seem to indicate that the current tally of Covid-19 deaths is actually an under-count.
But whatever the actual morbidity counts are, there is no doubt that this is a serious illness, claiming way too many lives. And for those who discount it as being no worse than the Flu, please remember that in 1918 and the surrounding years, the Spanish Flu pandemic also took the lives of way too many otherwise healthy individuals. That bug wasn't "like the flu" it WAS the flu.
