The city of Wuhan, the epicentre of China’s coronavirus outbreak, plans to conduct city-wide nucleic acid testing.
It is billed to last 10 days.
Every district in the city has been told to submit a detailed testing plan by Tuesday.
The city of 11 million people reported its first cluster of new infections over the weekend.
This came after a months-long lockdown was lifted on April 8.
An official of the party in the most affected area has been sacked.
The Wuhan health authority could not be immediately reached for comment
