Yet their death rate numbers are still lower than New York, New Jersey, Massachusetts, and expect Rhode Island and Connecticut to pass them as well.Read up on how herd immunity works. You'll get it.
If 70% of people cannot transmit the virus, the virus will infect fewer people. As a result, the daily case count goes into decline.
This is what the North Dakota did. They gave themselves at least partial herd immunity by infecting the vast majority of the population. Now, as expected, daily cases are low but overall cases are high.
It also looks like they will bury one person out of every 500.
Plus they show 90K cases out of 750K population. Where are you getting 70% infected?
