The Health 202: Genetic tracing could show how coronavirus spread through White House (Washington Post)

Washington Post: The Health 202: Genetic tracing could show how coronavirus spread through White House. “The Trump administration could, if it chose, search samples taken from dozens of White House staff members and visitors for tiny genetic variants. Because the virus undergoes slight changes as it moves from person to person, it’s possible to map where it has moved by looking for similarities in mutations. White House spokesman Judd Deere said tracing has been done for people who had contact with Trump. But it’s the kind recommended by the Centers for Disease Control and Prevention, which involves merely tracking people who were nearby those known to be infected.”
