BEIJING (AP) – Russia has reported its highest one-day jump in new coronavirus infections as some other countries and U.S. states where numbers of cases are stabilizing allowed businesses and public activities to reopen. China, where the pandemic began in December, reported one new infection, extending a decline in confirmed cases. The country has allowed factories and some other businesses to resume work, along with some tourist spots for this weekend’s May Day holiday. South Korea reported six new cases, none in the hard-hit city of Daegu. In the United States, more than a dozen states including Texas allowed restaurants and some other businesses to reopen. The first drug shown to help fight the disease received emergency approval from the U.S. Food and Drug Administration.
