BEIJING (Reuters) – The city of Wuhan, the original epicentre of the new coronavirus outbreak in China, conducted 1,000,729 nucleic acid tests on May 21, the local health authority said on Friday, compared with 887,321 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 on May 9-10 its first cluster of COVID-19 infections since its release from a virtual lockdown on April 8.
