Authorities in China introduced new COVID-19 curbs in areas surrounding Beijing on Tuesday, putting 4.9 million residents under lockdown as new infections raised worries about a second wave.
The number of new cases in mainland China reported on Tuesday almost halved from a day earlier and remain a small fraction of what it saw at the height of the outbreak in early 2020.
However, local authorities are implementing strict curbs whenever new cases emerge to prevent the kind of economic paralysis seen a year ago.
The National Health Commission reported 55 new COVID-19 cases on Tuesday, down from 103 a day earlier. Hebei province, which surrounds Beijing, accounted for 40 of the 42 locally transmitted infections, with the capital and northeastern Heilongjiang province reporting one local case each.
The city of Langfang in Hebei on Tuesday said its 4.9 million residents will be put under home quarantine for seven days and be subject to mass COVID-19 testing in the latest attempt to curb the spread of the coronavirus.
Two counties under Langfang's jurisdiction that border Beijing, Guan and Sanhe, had already announced home quarantine measures. Guan reported one COVID-19 case but Sanhe did not say whether any of its residents were diagnosed with the disease.
Shijiazhuang, Hebei's capital, has been hardest hit in the latest surge in infections and has already placed its 11 million people under lockdown. The province has shut off certain sections of highways and is ordering vehicles registered to Shijiazhuang to turn back.
Gaocheng district in Shijiazhuang is gathering more than 20,000 people living in 12 remote villages into centralised quarantine as part of the city's COVID-19 control, state media China News Service reported late Monday.
Authorities in Beijing's Xicheng district said on Tuesday that the confirmed COVID-19 patient from Guan county works at a building in the district.
A new guideline issued by the Beijing Center for Disease Prevention and Control recommended that taxi and ride-hailing operators suspend car-pooling services, the Communist Party-backed Beijing Daily reported on Tuesday.
The guideline also said that drivers should get a nucleic acid test for coronavirus every week and be vaccinated in order to work.
