Interested in thoughts on this.

R1b European populations appear to have higher COVID-19 deaths, while R1a appear less affected.

This is controlled for different start time of the epidemic by counting deaths at 28 days past the date of 1000 cases (the last country is therefore Greece, that reached 1000 cases on March 29th, deaths counted on April 26th).

All countries had isolation measures - except Sweden which is excluded.

If this correlation is correct, all countries <0.8 R1b could relax isolation measures with minimal adverse effects (Sweden levels).

Similar populations should have similar death rates. Looking at UK (>300/Million) vs. Australia (3/Million), this possibly indicates Vitamin D plays a role. Australia was in summer, with vit. D generated from UV exposure in skin. UK was in the middle of winter.

This implies COVID-19 should wane during the summer in the northern hemisphere, and come back in late winter when Vit. D levels fall in general population.

All countries may have had isolation measures, but those were implemented at a significantly different time. PL and CZ were among the first countries to implement lovkdowns, and they did those when the number of cases was 10-100 less than the other countries.

Not mentioning that is in my opinion scientifically dishonest.

Other arguments: - the correlation between a stop of disease growth and the implementation of containment measures is very clear now

- I don’t know about CZ, but in Poland we have a high death rate compared to the number of found cases, even though we test more samples than Germany to find one case. If anything, it would actually suggest that the death rates are higher here than in DE, not the other way around.

The concept of haplogroups affecting covid is not new. The critique is also there - posting a new chart about the subject and not mentioning of critique is dishonest as well, imho.
