This interactive map shows the spread of the virus that causes COVID-19 around the world since late January. Health officials in China first announced they were treating dozens of cases of an unknown illness on Dec. 31 and reported the first known death from the new coronavirus on Jan. 11. The data used to compile this map comes from Johns Hopkins University, which first shared its dashboard of cases, deaths and recoveries for affected countries on Jan. 22.
