After doing some research, I wonder if there some connection between haplogroups and current coronavirus mortallity. I've identified J2 as being the dominant Y-chromosome haplogroup in much of Italy, Turkey, and a significant portion of Iran. As a side note, I did some searching to see if perhaps mortality in the most hard hit countries at the moment was connected to behavior of the citizens in these two hardest hit countries, Italy and Iran, and they have, on average, lower instances of comorbidity [obesity, cardiovascular disease, etc] and of smoking (https://en.wikipedia.org/wiki/List_of_countries_by_cigarette_consumption_per_capita) when compared to a world average or to China for example by the above link - so I don't believe that is the answer. I do understand the overwhelming of any healthcare system contributes to an increased mortality rate, but I really don't think volume and population density can explain the covariance we see in the reported numbers from Worldometer. Italy does have a majority of the population over the age of 45; a third over the age of 60 by their population pyramid https://www.populationpyramid.net/italy/2019/ , so perhaps that is the reason as this virus tends to be more virulent in the elderly, but I still don't think it can explain all the covariance. Iran, for example, has the reverse situation with a sizeable majority under 45, and a third of the population under 25 - yet they still have strangely high numbers.
Finally, an interesting factoid about J2 haplogroup: Bernie Sanders, Ben Affleck, Dr. Oz, Adam Sandler, and The Rothschild family, among other famous families and people, are also descendants of haplogroup J2. This is still a very tentative, very early, remedial guess... but I'm trying to do my best in figuring out what's going on right now
