On Monday, city health authorities reported six locally transmitted Covid-19 cases in Shanghai, of which five were asymptomatic.
Shanghai, China’s financial capital and home to 25 million people, was locked down for two months earlier this year, leading to widespread public anger as residents reported difficulties in ordering daily essentials including food and medicine.
The lockdown was imposed under China’s rigid zero-Covid policy, which relies on mass testing, extensive quarantines and even confinement 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 control people’s movements and curb the spread of the virus.
People in many Chinese cities must present a green health QR code to ride public transport and enter venues including shopping malls, gyms and restaurants. The system logs their whereabouts and whether they have been in contact with a confirmed Covid-19 case — those whose health codes turn red face almost certain confinement to quarantine facilities.
Snap lockdowns have become common in the country, with the public growing increasingly frustrated with the stringent rules as the economy struggles to adapt to the disruption.
