Read excess death count.
This number can not be explained away by “faking” the cause as COVID19.
There a huge spike in excess deaths starting with when the US was hit by COVID. This is the same in European Countries hit by COVID. The spike does not occur in Countries that addressed COVID early (New Zealand Vietnam etc)
In the USA the excess death count is now over 300000 since march 2020. That is 330000 more deaths then would have been expected to occur to tall the things you mention and the common flu.
This another look showing the number of deaths that occurred before COVID , expected versus actual. It older as this published in May but it gives an idea of the impact of COVID.
This a graph looking at Countries the World over. Again virtually all saw a spike in excess death rates all starting at the same time.
This can not be due to “bonuses” paid to Hospitals to claim a death “COVID related” . It world wide and those bonuses do not explain the spike in deaths. Note how the Countries that have the lowest per capita deaths due to COVID also saw much less in the way of spikes in excess death count.
