China moved swiftly Monday to try to control a new outbreak of the coronavirus after 36 more cases were confirmed in Beijing.

There had been almost no new COVID-19 cases in the city for almost two months until an infection was reported on June 12, and since then the total number has climbed to 51, including eight more in the first seven hours of Sunday.

China has reported 4,634 deaths from COVID-19, a figure that has been static for weeks, among 83,064 total cases since the virus was first detected in the central Chinese industrial city of Wuhan.
