In a news conference on Sunday, Zhao Dandan, deputy director of the Shanghai Health Commission, said the “store and the affected area” would be under “closed loop” management for two days. People within the circle must undergo two days of quarantine and five days of health surveillance.
On Monday, the city’s health authorities reported six locally transmitted cases of Covid-19 in Shanghai, five of which were asymptomatic.
Shanghai, China’s financial capital and home to 25 million people, was locked down for two months earlier this year, sparking widespread public anger as residents reported problems ordering daily necessities, including food and medicine.
The lockdown was imposed under China’s rigid zero-Covid policy, which relies on mass testing, extensive quarantines and even incarceration of entire cities to stamp out any resurgence of the virus.
Relying on mobile technology and big data, the Chinese government uses a color-based “health code” system to monitor people’s movements and contain the spread of the virus.
People in many Chinese cities are required to present a green health QR code to travel on public transportation and enter locations including shopping malls, gyms and restaurants. The system records their whereabouts and whether they have been in contact with a confirmed Covid-19 case – those whose health codes turn red will almost certainly see confinement in quarantine facilities.
Snap-lockdowns have become common in the country, with the public growing increasingly frustrated with the strict regulations as the economy struggles to adjust to the disruption.
Last week, more than 80,000 tourists were stranded in the popular holiday resort of Hainan after authorities announced lockdown measures to contain an outbreak of the virus.
