Beijing — China‘s capital, Beijing, began mass testing of more than 3 million people on Monday to find COVID-19 cases and restricted residents in one part of the city to their compounds, sparking worries of a wider Shanghai-style lockdown. While only 70 cases have been found so far in the city of more than 21 million since a new outbreak surfaced on Friday, authorities have rolled out strict measures under China’s “zero-COVID” policy to try to prevent a further spread of the virus.
 
Some residents worked from home and many stocked up on food as a safeguard against the possibility that they could be confined indoors, as has happened in multiple cities, including the financial hub of Shanghai. The city of Anyang in central China and Dandong on the border with North Korea also started lockdowns as the omicron variant spreads across the vast country.
 
Shanghai, which has been locked down for more than two weeks, reported more than 19,000 new infections and 51 deaths in the latest 24-hour period, pushing its announced death toll from the ongoing outbreak to 138.

Long lines formed in supermarkets in central Beijing. Shoppers snapped up rice, noodles, vegetables and other food items, while store workers hastily restocked some empty shelves. State media issued reports saying supplies remained plentiful despite the buying surge.
 
Shoppers appeared concerned but not yet panicked. One woman, carrying two bags of vegetables, eggs and frozen dumplings, said she was buying a little more than usual. A man said he isn’t worried but is just being cautious since he has a 2-year-old daughter.
 
Beijing health officials said 29 new cases had been identified in the 24 hours through 4 p.m. Monday, raising the total to 70 since Friday.
 
The city has ordered mass testing across sprawling Chaoyang district, where 46 of the cases have been found. The 3.5 million residents of Chaoyang, as well as people who work in the district, need to be tested on Monday, Wednesday and Friday.

Testing sites were set up overnight and in the early morning at residential complexes and office buildings around the district.
 
“I think Beijing should be fine,” said Gao Haiyang as he waited in line for a COVID-19 test. “Based on the previous response made by my community, if there’s any emergency, I think supply can be guaranteed. Plus, there were lessons we learned from other cities. I think we can make good preparations.”
 
Shanghai has buckled under a strict lockdown that has driven residents to band together to get food delivered through group buying. Goods have backed up at the port of Shanghai, affecting supplies and factory production and putting a crimp on economic growth.
 
Beijing locked down residents in an area about 1 by 2 miles, telling them to work from home and stay in their residential compounds. It wasn’t a total lockdown – stores continued to operate – but cinemas, karaoke bars and other entertainment venues were ordered closed.
 
Elsewhere, the city also shut down some or all buildings in five residential compounds, adding to others that were locked down on Sunday.
