It is no coincidence that diseases such as the flu are more common in men. We’ve seen this during the Covid pandemic as well. One of the risk factors for severe disease in the pandemic was ‘being a man’. In a UK study, men were 60 percent more likely to die from coronavirus than women. Likewise, men are twice as likely to die from tuberculosis and flu than women. Recent studies on the reason for this point to the estrogen hormone, which is much higher in women.

Estrogen hormone plays a very active role in triggering immunity. However, the male hormone testosterone weakens immunity. In addition, most of the genes that play an important role in immunity are located on the X chromosome. Men have one X chromosome, while women have two X. This ensures that women have twice the genetic variation to fight disease.
WHY ARE SOME PEOPLE IMMUNE SO STRONG?
We also saw in Covid-19, some people managed to overcome the disease very mildly, despite being repeatedly infected. Even though they had never met this virus in their previous lives, their immunity was able to gain a great advantage against the virus. The University of Sheffield in England determined that 1300 genetic differences play a role in those who do not catch the coronavirus and are not seriously ill. In other words, genetic characteristics are important in immunity. People who have never been sick are indebted to their parents, and even to their ancestors, for passing these genes on to them.
