Not a surprise given the news yesterday that one person there has died of the disease and two more, a teenager and a woman in her 50s, are presumptive positives. A fourth man from Washington was diagnosed with COVID-19 in January after traveling in China near Wuhan; he’s now completely recovered, but God only knows how many people he may have infected at the Seattle airport or elsewhere in the community before he was diagnosed.
Flu researchers in Seattle sequenced the genome of the strain of coronavirus in the man who died and compared it to the strain in the man who was diagnosed in January. Were they distinct? Or were they related, which would be circumstantial evidence that the strain had spread through the community via patient one en route to patient two?
