Shanghai announced more than 21,000 new local cases on Friday, of which only 824 had symptoms. Total cases in the outbreak that began last month in Shanghai have soared past the 100,000 mark
China has repeatedly enforced lengthy mass lockdowns over the two-year course of the epidemic. Shanghai, however, had largely escaped the most onerous measures under China's “zero-COVID” strategy that aims to isolate every infected person.
Home to many of China's wealthiest, best educated and most cosmopolitan citizens, the city was first promised a two-phase lockdown starting March 28 and lasting no more than eight days total. With little notice given, residents made a run on supermarkets, quickly leaving shelves bare.
Those measures have since been extended, leaving many families that had planned for only a limited time in quarantine without supplies. Authorities say they will determine future steps based on testing results, but have given no specifics.
City officials have apologised for mishandling the lockdown and promised to improve food supplies. The Communist Party leadership in Beijing is working to squelch complaints, especially online, in hopes of preventing the lockdown and accompanying dissatisfaction from becoming a political issue ahead of a key party congress later this year.
Officials say Shanghai, home to the world's busiest port and China's main stock exchange, has enough food. But a deputy mayor, Chen Tong, acknowledged Thursday that getting it the “last 100 metres” to households is a challenge.
The government says it is trying to reduce the impact of its tactics, but authorities are still enforcing curbs that also block access to the industrial cities of Shenyang, Changchun and Jilin with millions of residents in the northeast.
