Covid19 first discovered November 17?
If Covid19 was discovered in China on November 17, it was probably in the US much earlier than we thought. We began testing in March.
The author reminds us that Knowing when the virus began and what we think occurred in January and February (and perhaps even December) will help determine not only how severe this virus is, but how far along we are into the epidemic. If we really had hundreds of thousands, if not millions, of cases, along with several thousand more fatalities prior to testing, that would mean that the mortality rate is even lower than the 1.2% post-testing average so far.
I found this an interesting article, and hope others here will as well.
