"There were a lot of people in line, incredibly desperate to get tested" because they were flying for the holidays, Kevin Bruyneel, a history professor based in Massachusetts, told the newspaper. "There was a lot of anxiety."
Problems with the testing in the United States began at the very beginning of the pandemic, when the U.S. Centers for Disease Control and Prevention distributed faulty test kits to laboratories in February 2020, the newspaper added.
