Shanghai, China’s financial capital and home to 25 million people, was locked down for two months earlier this year, sparking widespread public outcry as residents struggled to order daily essentials including food and medicine.
The lockdown was imposed under China’s strict zero-covid policy, which relies on mass testing, extensive quarantine and even the containment of entire cities to prevent a 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 prevent the spread of viruses.
Many Chinese cities require people to present a green health QR code to ride public transport and enter places 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 are almost exclusively confined to quarantine facilities.
