One year ago yesterday, a notice sent to smartphones in the city announced the world’s first coronavirus lockdown. Now life has largely returned to normal for the 11 million residents of the city where Covid-19 was first detected. Wuhan accounted for the bulk of China’s 4,635 deaths, but has been largely free of further outbreaks since lockdown was lifted on April 8. Questions, however, remain over the virus’s origins – and the authorities’ response.
