The article is poor.

Gøtzsche's basic idea is:
The proportion of SARS-CoV-2-infected people who die of the disease COVID-19 is comparable to that of flu; i.e. the infection fatality rate (IFR) for COVID-19 is not an order of magnitude larger than that of the flu.

Gøtzsche is wrong. Study after study shows that the fatality rate for SARS-CoV-2 is about an order of magnitude larger than that of influenza; COVID-19 is way more dangerous than the flu.
So where does Gøtzsche go wrong?

Gøtzsche calls this, "a 2020 review by John Ioannidis, which is in press in the Bulletin of the World Health Organization."
Interestingly, the World Health Organization does not agree with Gøtzsche.

Gøtzsche then cites his book to say the CDC may be unreliable on influenza's IFR.
But the CDC doesn't give an influenza IFR. They give a case fatality rate (CFR), where reported cases are limited to symptomatic illnesses

Influenza IFR can be calculated from the CFR, yielding an IFR of <0.1%. That extends beyond the CDC.

Gøtzsche goes on to compare *CFRs* from other pathogens to the *IFR* of SARS-CoV-2. That's misleading since IFR is less than, or equal to, CFR. In fact, IFR is almost always less than CFR, since CFR misses some infections.

A good illustration of this is Gøtzsche comparing SARS-CoV-2's *IFR* to a 1% *CFR* for the 2009 pandemic flu.
But the 2009 pandemic's *IFR* was around two or three orders of magnitude less

Gøtzsche cites a blood donor research to claim a SARS-CoV-2 IFR of 0.16%. That's:
- cherry-picking
- using a type of study that under-estimates IFR for multiple reasons
- citing a source that doesn't give an IFR
- the research implies a larger IFR

Evidence also does not support Gøtzsche's claim that "draconian measures" (
; see part 2/P) in response to COVID-19 caused poverty, not COVID-19.
For example, Sweden's less stringent response wasn't better in terms of GDP:

Gøtzsche's article is thus filled with false claims and distortions, leading to his politically-motivated conclusion.
But how could he do this? He should have the biological knowledge to see his claims are wrong.

One plausible explanation is that Gøtzsche's ideological opposition to some policy responses to COVID-19, pushed him to contrarianism on COVID-19. His contrarian tendencies appeared before, just as with John Ioannidis:

So the COVID-19 pandemic brought out ideologically-motivated contrarianism and denialism, just like the AIDS pandemic, anthropogenic climate change, vaccination, GMOs, etc. did.
