Beijing on Friday. The city has recorded 205 new cases since June 11. A new case related to the outbreak in neighbouring province Hebei was also reported on Friday.

Authorities have scaled up efforts to stem the transmission of the disease in Beijing, testing more than 2 million in the city of 20 million since June 13. “Currently, the city has the ability to sample an average of 500,000 people per day,” Zhang Qiang, a member of Beijing’s epidemic control office, said at a press conference on Saturday.
