- Residents told not to leave homes, with closed loop for businesses

- Buses, subways, ferries, taxis, and online car-hailing services suspended in locked down regions

Shanghai is kicking off a new round of nucleic acid testing for residents on Monday morning to curb the spread of the novel coronavirus, protect people's lives and achieve zero spread outside virus transmission chains as soon as possible.

The municipal government announced on Sunday night that the testing will begin in regions east of the Huangpu River. From 5 am Monday to 5 am Friday, the regions will be locked down while residents are tested.

The rules also apply to key subdistricts in Puxi, west of the river, which are already under lockdown and tested frequently.

From 3 am Friday to 3 am April 5, other regions in Puxi will be locked down while residents are tested.

Shanghai authorities said on Sunday that the city recorded 2,676 new locally transmitted COVID-19 infections, including 45 confirmed cases, on Saturday. Daily new infection numbers have climbed since the city's worst outbreak started early this month.

The city government will require all residential compounds within locked down regions to implement strict lockdown measures and all residents must stay at home. Residents and their cars will be allowed to enter neighborhoods, but they will not be allowed to leave. Express parcels will only be allowed to be delivered to the gates of neighborhoods.

All enterprises in locked down regions must operate under closed-loop management or allow employees to work from home, except for those offering essential public services.
