Coronavirus: Man Have More Risk to Be Infected by Coronavirus, Why?
Researchers suspect that the coronavirus is hitting men and women differently. Worldwide, men appear more likely to suffer more severely or die from COVID-19 than women. As the coronavirus sweeps across the globe, one pattern remains consistent: Men seem harder hit by the virus than women and are more likely to have severe illness or die.
And early in China research on coronavirus cases, the proportion of males to females in infections in China is 1.06: 1, but the crude mortality rate for males is 2.8% and for females is 1.7%. That is to say, although the number of men and women infected with new coronary pneumonia is roughly equal, the mortality rate of men is higher.
But experts don’t know why. At Johns Hopkins University, researchers have begun to wonder whether biological factors — like women’s immune systems producing a stronger response than those of men — can help explain the difference.
Sarah Hawkes, a professor of global public health at University College London, has also been looking at global COVID-19 data. Her research has found that men have been 50% to 80% more likely to die from COVID-19 than women.
So far there have no final conclusion about this topic. Some summarize some points why man are more likely to be infected and died from COVID-19.
Men ’s immune response to infection is weak
Janine Clayton, director of the Office of Women ’s Health Research at the National Institutes of Health (NIH), believes that this is because there is something more active in women ’s immune systems. It is prone to autoimmune diseases such as rheumatoid arthritis and lupus. Women are more than three times more likely to suffer from autoimmune diseases than men.
The reason for the stronger female immune response is not fully understood, but there is a hypothesis that the stronger female immune system brings survival advantages to its offspring. When the baby’s immune system is still developing, it can be absorbed from breast milk Antibodies help fight disease.
This is caused by a series of female biological factors, including female estrogen. In addition, women carry two X chromosomes containing genes related to immunity, while men carry only one.

Differences in health behavior
Women tend to seek medical services more easily than men, making women more likely to get early diagnosis and treatment in specific diseases, while men generally go to the hospital when the condition is more serious.
Data from around 1.5 million tests done in the U.S. show that the majority of people tested, 56%, were women. Of those women, 16% tested positive for the virus. In contrast, only 44% of the tests were done on men. And 23% of them tested positive.
Yako University’s immunology professor Akiko Iwasaki, who specializes in studying the impact of viruses on women, said men may have a “wrong sense of security” for coronaviruses. For example, the act of washing hands.
Harris Interactive conducted a telephone survey of over 1,000 adults in the United States and observed that they washed their hands after using public toilets. It was found that women wash their hands more frequently than men. In this epidemic, public health experts have repeatedly emphasized hand washing, but the New York Times reported that several studies have found that men, even medical staff, are less likely to wash hands or use soap than women. Although hand washing does not completely prevent the spread of disease, it certainly reduces the risk of widespread infection.
A recent research reported in May 11, in Europe showed that in men ’s blood, a kind of enzymes in man’s blood which is used to infected human body cells by coronavirus has much higher level than in women blood. This finding may help explain why men are more likely to be infected.
Reported by Reuters in London on May 11, angiotensin-converting enzyme 2 is present in the heart, kidneys and other organs. It is reported that this enzyme plays a role in the infection of the lungs in the new coronavirus pneumonitis caused by the novel coronavirus.
Izia Sama, a doctor at the Medical Center of the University of Groningen, said: “When we found that one of the strongest biomarkers, angiotensin-converting enzyme 2, is much higher in men than women, I realized that This may explain why men are more likely than women to die from new coronary pneumonia. "
Hi, Man, it is time to be more cautious, wash hand more times, and not hanging outs all the time without mask but staying at home, because you are weaker in the battle with COVID-19.
