China recorded 57 local Covid-19 cases on Sunday, the highest number the country has seen since it brought the coronavirus largely under control in March, according to figures released by the National Health Commission on Monday.
Among the locally transmitted cases, 41 were found in the far western region of Xinjiang, where the coronavirus resurfaced on July 15 after nearly five months of no new cases.
The remaining cases were discovered in the country's northeast, including 14 in Liaoning province and two in Jilin province.
Sunday's figure is the highest number of local infections the country has reported since March 6, surpassing the daily spikes during a coronavirus outbreak in Beijing last month.
On Sunday, China also recorded four imported cases and 44 asymptomatic infections. The country does not include asymptomatic cases in its overall tally of confirmed infections.
As of Monday, China has reported a total of 83,981 confirmed cases, including 4,634 deaths, according to the NHC.
