Why Shanghai’s gentle Covid-zero policy failed

Shanghai is China’s most important financial hub as well as the regional headquarters of global brands such as Apple Inc, Tesla Inc and LVMH Moet Hennessy Louis Vuitton SE. Until recently, it also executed China’s “dynamic clearing” Covid policy better than the country’s other municipalities. With a staff of over 3,000 conducting contact tracing in the city of 25 million, Shanghai never had to undergo mass testing or district lockdowns. For two years, life was pretty much normal.
It is thus a shock when Shanghai announced a lockdown to conduct mass testing over eight days. This is a sharp U-turn from an official stance that had ruled out such drastic measures. What went wrong?
Call it a winner’s curse. The capital city of Beijing is known for
imposing draconian 21-day quarantines on whole districts to deal with outbreaks, but Shanghai took a more gentle and targeted approach. In January, when the first local omicron cases were detected, only a single bubble tea shop
was classified as “medium risk,” thereby avoiding lockdowns of entire city blocks. Early March, when cases started to rise, Shanghai still deployed a “2+12 days” model, locking down residential buildings with close contacts for mass testing for two days and letting its residents roam about as soon as PCR results all came out negative.
Shanghai’s mass testing relied on dutiful, conscientious citizens. Medical staff did not go knocking door to door; rather, testing booths were set up in gated communities or on the streets.
It is likely the number of people who did not bother to get tested was significant. The government posted a notice saying that those who did not comply would see their health code flip into yellow, which would restrict their ability to go shopping or even take public transportation. The number of cases skyrocketed after.
There’s always a bit of rivalry between Shanghai and Shenzhen. This time, the tech hub seems to be doing better than the financial center: It just came out of a one-week lockdown relatively unscathed.
Shenzhen was not as laissez-faire. By early March, city employees there were already sifting through apartments owned by the so-called urban villagers, looking underneath beds and inside closets, to make sure everyone got tested. Flats like these often serve as unofficial residences for migrant workers from other parts of the country. China’s strict Covid policy might still work if cities go into lockdowns early, which enables them to come out faster too. Shenzhen, a city of 17 million, came to a stand-still when just 66 cases were found.
