Chinese authorities have announced mass coronavirus testing in Wuhan as an unusually wide series of Covid-19 outbreaks reached the city where the disease was first detected in late 2019.

Wuhan, a provincial capital of 11 million people in central China, is the latest city to undergo city-wide testing. Three cases were confirmed there on Monday, its first non-imported cases in more than a year.
