BMI is a horrible metric.
No, its not a great metric. It doesn't calculate lean body mass in those that exercise and/or do restensce training and have more LBM than the average. The point is that obese people are really suffering severely if stricken with the virus. A man with a waist bigger than chest and a double/triple chin and pre-diabetic or with diabetes is going to have a rough time according this guy.
