The COVID formulation definitely targets the obese which often includes those with diabetes, high blood pressure, and other issues of metabolic syndrome which include hypercoagulability (excessive tendency toward blood clotting) as well as chronic hyperinflammatory states. There are people groups that are more prone than others to these conditions. (I intentionally omit the word race for differentiation because I contend there is only one human race which has various sub-groups.) I’m not sure the ‘target group’ was intentional, but some of those sub-groups are at higher risk for metabolic syndrome, whether via lifestyle or heredity, probably both, therefore making them more at risk for COVID with complications and higher risk for death.
