The city of Wuhan, the original epicentre of China's coronavirus outbreak, conducted 856,128 tests for the disease on Tuesday, the local health authority said on Wednesday, compared with 467,847 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 the city's lockdown was lifted on April 8.
