The Chinese city of Wuhan, where the novel coronavirus outbreak first emerged, found no new cases of COVID-19, the disease caused by the virus, and 300 asymptomatic cases in city-wide testing that began in mid-May, officials said on Tuesday.
The city launched its ambitious campaign on May 14, testing 9.9 million people, after a cluster of new cases in the city raised fears of a second wave of infections.
But authorities found no new cases of the disease in the May 14 to June 1 testing, officials told reporters in a briefing, adding that the asymptomatic cases were found to be not infectious.
