SHANGHAI (Reuters) — China’s financial hub of Shanghai said Sunday that it would lock down the city in two stages to carry out COVID-19 testing over a nine-day period, after it reported a new daily record for asymptomatic infections.

Authorities said they would divide Shanghai into two for the exercise, using the Huangpu River that passes through the city as a guide. Districts to the east of the river, and some to its west, will be locked down and tested from Monday to Friday. The remaining areas will be locked down and tested between April 1 and 5.

Public transport, including ride-hailing services, in these areas will be suspended when they are locked down, the city government said on its official WeChat account, adding that unapproved vehicles will not be allowed on the roads.

It also said that all firms and factories will suspend manufacturing or work remotely during the lockdown, apart from those involved in offering public services or supplying food.

“The public is asked to support, understand and cooperate with the city’s epidemic prevention and control work, and participate in nucleic acid testing in an orderly manner,” the government added.

Shanghai has battled a new COVID-19 surge for nearly a month and for Saturday it reported its highest daily number of cases since the initial outbreak in China receded. The city recorded 2,631 new asymptomatic cases, which accounted for nearly 60% of China’s total new asymptomatic cases that day, plus 47 new cases with symptoms.

While the number of cases in Shanghai remains modest by global standards, the city of 26 million people has become a testing ground for China’s “zero-COVID” strategy as it tries to bring the highly infectious Omicron variant under control.

Shanghai authorities have previously resisted a broad lockdown of the city to avoid destabilising its economy and opted for a more bespoke “slicing and gridding” approach, which involves screening neighbourhoods one by one.

STOCK EXCHANGE

The city houses factories belonging to the likes of Tesla TSLA.O, Volkswagen VOWG_p.DE and the country’s largest chipmaker SMIC 0981.HK, as well as the mainland China headquarters of many international companies.

The Shanghai Stock Exchange said Sunday that it would work to maintain the steady operation of capital markets during this “special” virus control period.

The bourse will continue to vet share sale plans by companies seeking to list on the tech-focused STAR Market, strengthen online communications with issuers and underwriters and offer free services for virtual debut ceremonies, it said.

The exchange will also allow listed companies to delay filings of their quarterly or annual reports if they’re affected by the pandemic restrictions, and will fast-track bond issuance approvals for virus-hit companies, it added.

FRUSTRATIONS

More than 14 million Shanghai residents have taken antigen tests, the Shanghai Municipal Health Commission said Sunday.

But some residents have grumbled about seemingly endless cycles of testing and the piecemeal approach to ending transmission chains, with some saying the cost of zero-COVID had become too high. 

Frustrations have also been felt elsewhere in China.

Earlier this month, in footage shared on social media, a crowd of people in the northeastern city of Shenyang banged against the windows of a clothing market as they shouted in frustration at yet another round of COVID-19 tests.

China reported a total of 4,448 new asymptomatic infections Saturday, up from 4,430 a day earlier, including 1,007 new cases in the northeastern province of Jilin, currently under lockdown.

The country reported 1,254 new confirmed cases with symptoms, down from 1,335 a day earlier. Of the new cases, 1,217 were locally transmitted, versus 1,280 a day earlier.

There were no deaths reported Saturday, leaving the death toll at 4,638. As of Saturday, mainland China had confirmed 143,240 cases of COVID-19.
