Wuhan in central China's Hubei Province tested nearly 10 million people between May 14 and June 1 in a citywide drive to screen novel coronavirus infections and found no confirmed COVID-19 cases in the process, according to a press conference on Tuesday. The city on May 14 launched a campaign to offer nucleic acid tests to those not tested before. Officials said the move was aimed at reassuring the society as the city reopens its factories, businesses and schools.
