It’s west coast samples with lots of travel so we can only make guesses about that area.104/7400 equal 1.41% of the U.S. population being already infected with the Covid 19 virus about one year ago.
How long does it take to get from Patient Zero to 1.41% of the population? One year?
That could mean a few persons first got infected with an early strain of the Covid-19 virus in the U.S. sometime during Jan 2019.
One year is a very long time. Are we supposed to believe that a coronavirus outbreak was happening in the U.S. since the beginning of 2019 without the U.S CDC knowing?
