For context, the WHO report officially has first known case (as told to them by China) as December 8th, and genome being sequenced as December 31st. Dr. Lipkin being told of an *outbreak* of interest or concern in Wuhan on December 15th is a pretty big deal.

Forgive me if this is already in your thread somewhere, but here's a slightly more detailed telling of how/when Dr. Lipkin found out, from The New Yorker. https://www.newyorker.com/magazine/2020/03/09/a-local-guide-to-the-coronavirus …pic.twitter.com/P3gmobUETO

In the Frontline doc “China’s Covid Secrets” Lipkin says he got a call from Gao on New Year’s Eve, and at the time “knew of many people infected”.pic.twitter.com/sQ53oXYIEO
