Men tend to get hit harder by every virus. It's scientifically proven that the man flu is a real thing. It sounds like I'm making this up but there is a Harvard study on it lol. I remember reading it has something to do with testosterone levels.
Here we go:
"
For example, in a 2016 study, researchers exposed male and female human nasal cells to estrogen in a lab dish, and then infected the cells with the flu virus. The investigators found that the estrogen reduced the levels of flu virus in the cells from female donors, but not male donors.
What's more, other studies have suggested that the "male" hormone
testosterone may lower the body's immune response to flu viruses, Sue said."
It is clear that men die at a higher ratio than women due to Covid-19, but it is not clear why. The post above I posted researched sourced numbers from China which demonstrated that men will die at a higher %, and it has also been anecdotally demonstrated in Italy.
You may be right that there is a biological explanation for that. The problem with science, even coming from Harvard, is that these findings also change overtime and are dependent on political and social norms at the time. For example in the past it was accepted science that races were different and had different sized brains, today that is no longer scientifically accepted and scientists often argue that there are no differences between races and genders biologically. So, I take your Harvard research with a grain of salt.
It makes the problem a lot easier to just say "its biological", rather than confront the reality that there may be social biases and discriminations in place that result in a higher % of men dying.
There is also a social norm that men should "man up", which results in men delaying treatment or even foregoing treatment to instead give it to a female. As I correctly pointed out, in times of crisis (wars, plagues, famines) it is men who die in the highest numbers and society tends to prioritize a woman's life over a man's. In Titanic, men died women lived. Same in wars. Same in the Spanish Flu of 1918, men died a lot more. Maybe this is because of a prevailing social norm that men are supposed to man up and face risks, while women's lives are prioritized more. The treatment of sick women in hospitals is possibly being prioritized over men's due to these social norms. The mainstream media will of course never report on this as being a possible explanation on the disproportionate amount of male deaths.
Ultimately, there is a social norm in place, and perhaps there always has been which in times of a crisis will prioritize a woman's life over a man's.
Regardless of "why", the fact is, and it is a fact, is that as a man your risk is doubled compared to the death rate of all cases. So when you see a death rate of all cases between 1.5-10% depending on country, that represents all cases, and as a man your risk of death is 1.5 to 2X that at least.
