The cinder block hallways inside the US Army’s top virus research lab are punctuated every few feet with windows that peer into tiny offices and laboratories crammed with scientific equipment. On each doorway, orange placards with that Vulcan-looking biohazard symbol keep visitors alert. Through one window, you can just make out the heads of two people dressed in Tyvek suits and respirators. They seem to be laughing about something, but their work is deadly serious.

The pair are growing the SARS CoV-2 virus in round plastic dishes. In February, the CDC sent the Army about 10 drops of blood from one of the first Covid-19 patients, a Washington state man in his fifties who was the epidemic’s first US death. Since then, the Army researchers isolated the virus and have been making more of it to ship to other labs designing a vaccine or treatment against coronavirus.
