China saw 61 new coronavirus cases on Monday – the highest daily number since April – driven by clusters in three different regions that triggered fear of a new wave.
The majority of the 57 new domestic cases were found in the far northwest of Xinjiang, where a sudden outbreak occurred in the regional capital, Urumqi, in mid-July, according to the National Health Commission.
Fourteen domestic cases were also recorded in the northeastern province of Liaoning, where a new cluster broke out in the city of Dalian last week.
Two other local cases were found in the neighboring province of Jilin near the North Korean border – the first since late May.
The last four infections confirmed on Monday were imported from overseas.
It is the highest daily number of new virus cases since April 14, when 89 most imported cases were registered.
The Chinese authorities have carried out mass tests for hundreds of thousands of people in the port city of Dalian.
A second wave of mass testing was launched on Sunday in Xinjiang's Urumqi to identify residents who had previously falsely tested negative, the state-run Global Times reported after a mass test earlier this month.
According to a local press conference on Friday, more than 2.3 million people in the city with 3.5 million inhabitants have been tested so far.
The outbreaks come when the Chinese Super League soccer tournament started its much belated season on Saturday.
Flatshares in Dalian and Urumqi have been banned and the authorities have declared a "war mode" to fight the virus.
Experts have not yet confirmed the origin of the youngest Xinjiang cluster, which has infected 178 people so far.
The new infections in Jilin were announced just a few days after President Xi Jinping completed a provincial inspection tour last week.
The area announced four new asymptomatic cases on Sunday after investigating travelers from Dalian.
A further 302 asymptomatic cases in China will be medically observed on Monday, according to the health authorities. There are currently 331 COVID-19 sufferers nationwide, 21 of whom are in severe condition.
