A good read:
From Wuhan to Paris to Milan, the search for ‘patient zero’ washingtonpost.com/world/asia_pac…
There were early rumors. One Wuhan resident, Stella Zhou, recalled to The Washington Post that she heard talk of a mysterious pneumonia at a child-care center on Dec. 8, 2019.
Note: Jamie Morris believes he may have contracted the virus in Wuhan at the end of November:
He was working in a kindergarten in Wuhan.
Also, as pointed by @franciscodeasis 1st GD family (Lineage A) was infected in a Children Hospital late December.
Maybe someone remembers some photo of some children hospital entrance in Wuhan in Nov or early Dec with a placard about increased cases of children respiratory illness cases.
Need to get back to that old tweet.
