I agree about avoiding hysteria, but IF "most" people got the virus...
Let's take "most" people to be 50% of the population. The Seattle Metro area had ~3.9 million people in 2017. The virus death rate is currently estimated at 2%.
So just accepting that 3.9m * 0.5 * 0.02 = 39,000 people will die in the the Seattle area alone seems a bit extreme
