China's Wuhan to test 'all residents' as Covid cases emerge after a year

Seven locally transmitted infections have been found among migrant workers in Wuhan, breaking a year-long streak without domestic cases.

Authorities in Wuhan on Tuesday said they would test its entire population for Covid-19 after the central Chinese city where the coronavirus emerged reported its first local infections in more than a year. The city of 11 million is "swiftly launching comprehensive nucleic acid testing of all residents", senior Wuhan official Li Tao said at a press conference on Tuesday.
