BEIJING — A Beijing government spokesperson said the city has contained the momentum of a recent coronavirus outbreak that has infected more than 200 people, after the number of daily new cases fell to single digits.

“The situation is developing in a good direction … but the prevention situation remains grave and complex,” Xu Hejian said at a Monday news conference.

Xu spoke after the city reported nine new cases in the previous day, down from more than 20 daily for eight straight days. A massive testing campaign found 236 confirmed cases of COVID-19 and 22 more without any symptoms. China does not include the latter in its official case count.

The Transport Ministry said tests of more than 100,000 of the city’s ubiquitous delivery drivers were expected to be competed Monday, as authorities expand testing to more groups.

The outbreak took hold in a huge wholesale food market crowded with workers and buyers. Additional cases traced to the same outbreak have been found in neighboring Hebei province and nearby Tianjin city.
