The average male only has one “X” chromosome. If Immune function is strong on the “X”, fabulous. If not, too bad, because there is no spare “X” that might have stronger function. Preliminary data is showing that beyond factors such as age and underlying chronic disease, males appear to be at greater risk of dying from a COVID-19 infection than females, despite the fact that females catch the disease more often than do males. Perhaps twice as likely to die than a comparable female. Part of that disparity likely relates to the fact that Immune Function, The Doctor Within, if you will, is carried by the “X” chromosome. For example, according to Global Health 5050, the ratio of M to F mortality in China is 1.7 to 1; 1.9 to 1 in Switzerland; in Ireland it’s 2 to 1; and 2.1 to 1 in South Korea, Denmark, and Greece. There is another contributing factor, however. More tomorrow.
