It was one year ago — Jan. 20, 2020 — that the first case of SARS-CoV-2 infection was reported on U.S. soil.
It was still called the “novel coronavirus” at the time; at least that’s how it was referenced in a CDC statement. By the time a final New England Journal of Medicine report on the case was published March 5, it had been dubbed 2019-nCoV as well as SARS-CoV-2.
