The first person in the U.S. known to be infected with a new and apparently more contagious variant of the coronavirus was identified Wednesday as a Colorado National Guardsman who had been sent to help out at a nursing home struggling with an outbreak. And health officials said a second Guard member may have it, too.
The cases have triggered a host of questions about how the mutant version circulating in England arrived in the U.S. and whether it is too late to stop it now, with top experts saying it is probably already spreading elsewhere in the United States.
“The virus is becoming more fit, and we’re like a deer in the headlights,” warned Dr. Eric Topol, head of Scripps Research Translational Institute.
