Shanghai will remain under lockdown as it reviews results of an exercise to test all of its 26 million residents for COVID-19, authorities said on Monday.
The city began its two-stage lockdown on March 28, initially in Shanghai’s eastern districts, and later expanded to cover the whole city.

The curbs, which have massively disrupted daily life and business operations in China’s financial hub, were initially scheduled to end at 5 a.m. local time (9 p.m. GMT) on Tuesday.

“The city will continue to implement seal and control management and strictly implement ‘staying at home,’ except for medical treatment,” the city government said on its official WeChat account.
It did not give an indication of when the curbs might lift.
The country sent the military and thousands of healthcare workers into Shanghai to help carry out COVID-19 tests for all of its 26 million residents on Monday, in one of the country’s biggest-ever public health responses.
Some residents woke up before dawn to stand in queues for white-suited healthcare workers to swab their throats as part of nucleic acid testing at their housing compounds.
The People’s Liberation Army (PLA) on Sunday dispatched more than 2,000 medical personnel from across the army, navy, and joint logistics support forces to Shanghai, an armed forces newspaper reported.
About 38,000 healthcare workers from provinces such as Jiangsu, Zhejiang, and the capital Beijing have been dispatched to Shanghai, according to state media, which showed them arriving, suitcase-laden and masked up, by high-speed rail and aircraft.
It is China’s largest public health response since it tackled the initial COVID-19 outbreak in Wuhan, where the novel coronavirus was first discovered in late 2019. The State Council said the PLA dispatched more than 4,000 medical personnel to the province of Hubei, where Wuhan is, at that time.
Shanghai, which began a two-stage lockdown on March 28 that has been expanded to confine practically all residents to their homes, reported 8,581 asymptomatic COVID-19 cases and 425 symptomatic COVID cases for April 3. It also asked residents to self-test on Sunday.
The city has emerged as a test of China’s COVID elimination strategy based on testing, tracing, and quarantining all positive cases and their close contacts.
The country has 12,400 institutions capable of processing tests from as many as 900 million people a day, a senior Chinese health official was reported as saying last month.
China’s primarily uses pool testing, a process in which up to 20 swab samples are mixed together for more rapid processing.
The city has also converted multiple hospitals, gymnasiums, apartment blocks and other venues into central quarantine sites, including the Shanghai New International Expo Center which can hold 15,000 patients at full capacity.
Individuals who refuse to be tested for COVID for no justifiable reason will face administrative or criminal punishment, Shanghai police said on Saturday.
The surge in state support for Shanghai comes as the city is straining under the demands of the country’s “dynamic clearance” strategy, with some residents complaining of crowded and unsanitary central quarantine centers, as well as difficulties in securing food and medical help.
Some have begun to question the policies, asking why COVID-positive children are separated from their parents. Western diplomats have also urged China not to do so.
On Monday Shanghai official Wu Qianyu told a news conference that children could be accompanied by their parents if the parents were also infected, but separated if they were not, adding that policies were still being refined.
There has also been increasing public questioning why mild or asymptomatic infections — the majority of Shanghai’s cases — cannot isolate at home.
A Shanghai resident, who declined to be named for privacy reasons, told Reuters he had been transported to a central quarantine facility on Sunday night after reporting a positive result on a self test more than a week ago.
Another antigen test on Saturday showed he was no longer infected, but authorities insisted on sending him to quarantine, where he has been put in a flat where he has to share a toilet with two other patients, both of whom are still testing positive.
“How is this isolation?” he said, adding that he was now afraid of being re-infected. “I’m not in any mood to do anything right now, I can’t sleep.”
On Monday, videos circulating on the WeChat messaging app showed scores of people rushing to grab bedding and supplies from the dirty floor of what the poster said was a quarantine center whose premises were still littered with construction materials.
Reuters could not independently verify the footage.
Workers under strain
The pressure on the city’s healthcare workers and Communist Party members has also been great, as they work around the clock to manage the city’s lockdown and deal with residents’ frustrations.
Photos and videos have gone viral on Chinese social media of exhausted workers and volunteers sleeping in plastic chairs or on the grass outside housing compounds, or being berated by residents.
On Saturday, the city’s Pudong Chinese Center for Disease Control said it was investigating a leaked recording of a call between a staff member and the relative of a patient, who was perplexed by his father’s COVID test results.
The CDC staff member, who local media identified as infectious disease expert Zhu Weiping, could be heard saying exasperatedly that she herself had raised concerns over the current quarantine and testing rules and that the virus had become a “political” one.
Reuters was not able to independently verify the recording which went viral on Chinese social media.
Users of the Weibo social media platform started a hashtag “protect Zhu Weiping,” which by Monday had 2.9 million views, amid concerns that she could face punishment for speaking out against the official line.
Chinese President Xi Jinping has urged the country to curb the momentum of the outbreak as soon as possible while sticking to the “dynamic-clearance” policy.
On Saturday, Vice-Premier Sun Chunlan, who was sent to Shanghai by the central government, urged the city to “make resolute and swift moves” to curb the pandemic.
The eastern city of Suzhou said it had detected a version of the omicron BA.1.1 subvariant that doesn’t match any others in the domestic database or the international variant tracking database GISAID, state television reported.
The state-backed Science and Technology Daily said it remains unclear whether the virus is a new sub-branch of omicron and that the emergence of one or two new versions is normal given the spread of omicron in China, citing an unidentified expert with a national database.
