Has there been general health suffering, absolutely, have people who are vulnerable caught it and subsequently dies, undoubtedly and to that end, its difficult to speculate on scenarios that were different than the ones that actually happened. There may be statisticians or modelling experts who could extrapolate data to try and predict, but that is a bit like predicting the weather, sure there is some science behind it, but there are just too many variables for certainty.
There is a very easy way to see if Covid has lead to more deaths. You look at the data of typical number of deaths per year before the pandemic and during the pandemic.
Here are the numbers for the US.
You can see the numbers of CDC.gov
As you can see there is significant increase in deaths in the US during the pandemic.
BTW: Here in New Zealand we have been very lucky in that we have been shielded from the pandemic for most of it. So not easy to read out anything here. From memory we might have actually had less deaths than usual during some of the lockdown period.
