Covid-19: Lockdowns begin as Shanghai reports record asymptomatic cases

China’s financial hub of Shanghai launched a planned two-stage lockdown of the city of 26 million people on Monday, closing bridges and tunnels, and restricting highway traffic in a scramble to contain surging local Covid-19 cases.

The snap lockdown, announced by Shanghai’s city government on Sunday, will split the city in two roughly along the Huangpu River for nine days to allow for staggered testing.

A record 3,450 symptomatic Covid cases were reported in Shanghai on Sunday, accounting for nearly 70 per cent of the nationwide total, along with 50 symptomatic cases, the city government said on Monday.

Shanghai’s Public Security Bureau said it was closing cross-river bridges and tunnels, and highway tollbooths concentrated in the city’s eastern districts through April 1. Areas to the west of the Huangpu River will have similar restrictions imposed April 1-5.

In a statement posted to its official Weibo account, the bureau said traffic controls would be implemented on highways into and out of the city, requiring people leaving Shanghai to show proof of negative results from nucleic acid tests taken within 48 hours.

The city government said on Sunday it would suspend public transport, including ride-hailing services, in locked down areas. It also ordered the suspension of work at firms and factories, with the exception of those offering public services or supplying food.

US automaker Tesla is suspending production at its factory in the city for four days, two people familiar with the matter told Reuters. Tesla did not immediately respond to a request for comment on Monday.
