Most of Shanghai has stopped the spread of the coronavirus in the community and fewer than 1 million people remain under strict lockdown, authorities said Monday, as the city moves toward reopening and economic data showed the gloomy impact of China’s “zero-COVID” policy. Vice Mayor Zong Ming said 15 out of Shanghai’s 16 districts had eliminated virus transmission among those not already in quarantine. “The epidemic in our city is under effective control. Prevention measures have achieved incremental success,” Zong said at a news briefing. Supermarkets, malls and restaurants were allowed to reopen Monday with limits on the numbers of people and mandated “no contact” transactions. But restrictions on movement remain in place and the subway train system remains closed for now.
