His real name, the one printed in the icy databases of the CDC, was SARS-CoV-2. But that was a lab name. It had no swagger. No personality . He preferred the moniker the terrified grad students whispered during all-nighters: “Sketchy.” Because everything about him was a little off, a little improvised, a little too clever for his own good.
