China's Wuhan says conducted 335,887 COVID-19 tests on May 17

The city of Wuhan, the original epicentre of the new coronavirus outbreak in China, conducted 335,887 nucleic acid tests on May 17, the local health authority said on Monday, compared with 222,675 tests a day earlier.

Wuhan kicked off a campaign on May 14 to look for asymptomatic carriers -- infected people who show no outward sign of illness -- after confirming earlier in May its first cluster of COVID-19 infections since it was released on April 8 from a virtual lockdown to contain the spread of the pathogen.
