Covid Flares Again in Shanghai, Putting Areas Back in Lockdown

Shanghai will lock down seven city districts this weekend to mass test millions of people as Covid-19 cases continue to emerge in the community, risking more disruption for residents and businesses that have just exited a grueling two-month shutdown. Authorities said late Thursday they would lock down the Pudong, Huangpu, Jing’an, Xuhui, Hongkou, Baoshan and Minhang districts of Shanghai, with residents to be tested for the virus -- a key tool in China’s Covid Zero arsenal. It comes after infections found in the community rebounded to six on Thursday, from zero the day before.
