Just checked, there are between 6,000 and 7,00 hospitals in 50 states.
If each hospital has 7 deaths that comes to minimum of 42,000 deaths.
So with so many hospitals in so many places, nobody would even consider that 7 deaths in one hospital could accrue a nationwide count of 42,000.
The doctors would not know from one hospital to the next regarding death counts, even if they did, say 3 hospitals, 15 died in a region. Big deal.
Very, very easy to coverup.
