Shanghai will briefly lock down most of the city this weekend for mass testing as Covid-19 cases continue to emerge, causing more disruption and triggering a renewed run on groceries days after exiting a grueling two-month shutdown.
The plan emerged from one area with a handful of cases, then spread in hours to 15 of the financial hub’s 16 districts. It encompasses almost all of the city’s 25 million residents as health officials use testing to root out any silent transmission of the virus, a key tool in China’s Covid Zero arsenal.
