From the American College of Cardiology Bulletin:


• Overall the case mortality rate remains low at 2.3%; however, the mortality rate
jumps to 6% in hypertensives, 7.3% in diabetics, 10.5% in patients with
cardiovascular disease, and 14.8% for patients ≥ 80 years of age

We have 10 MILLION immune-compromised.

We have 47 MILLION senior citizens.

We have 35 MILLION smokers.

We have 98 MILLION with hypertension.

We have 34 MILLION diabetics.


...

THAT IS LITERALLY MORE THAN HALF THE NATION. IN FACT, THAT IS 294 MILLION AT RISK OF SEVERE COMPLICATIONS, CLOSER TO THE WHOLE POPULATION OF THE COUNTRY.
