It’s interesting to note the scale and mortality of those various flu seasons, almost half the number of Covid 19 deaths and far greater numbers infected however the reaction by governments could not be further apart.
I suspect a certain level of official hysteria Has helped to fan the unease in the populace.
If we look around the world, we see that the worst recent flu season (2018-19) in the USA killed fewer than half the count of covid-19 deaths
so far, & for flu that's the final total, using different methods to estimate the number. It was 61,000 "flu-associated" deaths. In the last decade, US annual flu deaths have fluctuated between 61,000 & 12,000 - i.e. fewer than 10% of covid-19 deaths counted to date. The running tally is never complete, & usually well below the final estimate.
The covid-19 epidemic in the USA is far from over (look what's happening in southern states which opened up early), has been kept damped down by control measures, & the death tally so far is very far from complete. Final figures for last month, for example, won't be available for a few months. And what would it be without the control measures?
It's safe to assume that using the same estimation methods as those for flu epidemics the covid-19 death figure would be significantly higher, & it ain't over yet.
Much the same applies to most other countries, though some are quicker at bringing out the retrospective estimates of totals. For Belgium, for example, the current covid-19 tally is likely to be complete (perhaps even an overestimate), but the Netherlands may have only counted half the covid-19 deaths so far.
