Most were in Xi’an, in the northwestern province of Shaanxi, where 13 million residents have been under lockdown since Thursday.
On Christmas Eve the city reported its highest daily count in a year with 75 domestic cases, according to the local health bureau Saturday.
While China has reduced cases to a minimum — thanks to a zero-COVID strategy of tight border restrictions, lengthy quarantines and targeted lockdowns — cases have been bubbling up in recent weeks.
Footage from state broadcaster CCTV Saturday showed long queues outside Xi’an testing centers as officials rushed to stamp out the latest flareup.
Under strict lockdown rules, since Thursday all households in Xi’an have only been permitted to send one member outside every two days to purchase necessities. Residents need special permission from their employer or local authorities to leave the city.
Xi’an has recorded 330 locally transmitted symptomatic cases since the first case was reported on December 9, 2021, few compared to outbreaks elsewhere in the world.
But some 26 Xi’an government officials have been punished for lapses in virus prevention, China’s disciplinary body said on Friday.
Local authorities who are deemed to have failed at controlling the virus in their region are regularly sacked or reprimanded under Beijing’s strict zero-Covid approach.
Cases from Xi’an have so far spread to five other cities including Beijing, according to state media, fueling fears about how quickly the virus can spread geographically across the vast country.
China has reported 100,871 symptomatic cases and fewer than 5,000 deaths since the virus first emerged in the city of Wuhan in late 2019.
