The coronavirus variant first identified in the United Kingdom is now the most dominant strain in the United States, the Centers for Disease Control and Prevention announced Wednesday.
Scientists have found that the variant, known as B.1.1.7, is 50 percent more contagious than other strains. In January, 76 cases of the variant had been identified in 10 states; it now accounts for roughly 27 percent of U.S. cases, with Florida, Michigan, and Tennessee seeing some of the highest case totals, The Washington Post reports.
