Shedding light on where #COVID19 replicates, informing transmission:

"Pharyngeal virus shedding was very high during the first week of symptoms...Infectious virus was readily isolated from throat- and lung-derived samples, but not from stool samples." https://go.nature.com/2X64lH4

Also: "Blood and urine never yielded virus."

Take-home points:

-Fecal-oral and blood transmission may not play a role

-In the context of other recent work, we may see viral transmission (from upper respiratory tract) before symptoms occur and in subclinical individuals
