Excellent explanation. I wanna add one more thing to this hypothesis. The individuals who are G6PD(Gluose-6-phosphate dehydrogenase enzyme) deficient which is responsible for the production of “reduced electron carrier NADPH” in the first reaction of Pentose Phosphate Pathway (PPP) which recycles the oxidised GSSG to GSH by Glutathione reductase. They are the ones who are susceptible to COVID-19 as they lack this enzyme in their gene which leads to build up of oxidative stress. There are significant population of these individuals.
