Re the infectious period.
Yesterdays TWiV 601 was an interview with a German Corona virus researcher on their experience and research. The gist was that the virus remained in the deep lung for a long time but that neither URT or fecal samples were infectious apart from early in the disease. They could get RNA in PCR tests but could not infect vero cells although around symptom onset, and a few days after, viral titers were very high and grew well.

when I listened I had thought Drosten were probably wrong about the containment and it went
to Italy and >50% of the world just from that Shanghai-woman via Webasto/Munich.
But I checked again ...
@c_drosten , Apr 13 ...[102] sequences from Germany ...
https://civnb.info/sequences/
and someone had anonymously leaked the semi-secret GISAID-mutations until mid-March (thanks a lot)
And then I read the Vo-paper.
@cmyeaton [Vo-paper] ... full of interesting results.... [compare with Drosten's Munich cluster]

The 3 Shanghai-Webasto mutations are C00241T,C03037T,A23403G.
Then somewhere,somehow C14408T joined the 3 and is now seen everywhere.
Italy Feb19;France Feb20,NL,CH,I Feb23;D-BW,Brazil,Finland,Spain Feb24,England,Ireland Feb25
Mexico Feb26
Maybe some other airplane from Shanghai with a C14408T superspreader.
They really should have checked all these airplane contacts including the Shanghai-Webasto flight.
They should also have asked in Vo about fever+cough in Jan or China/Germany travel history
btw. I just saw this : [add to the Drosten immune podcasts]
@florian_krammer Excellent review of human immune responses to coronaviruses!
The best one I found so far. I already cited it
