Chinese authorities have told residents of two cities in Hebei Province, near Beijing, to stay home for at least seven days as coronavirus cases increase in the province.
According to the National Health Commission, a total of 334 new infections were confirmed in Hebei in the week through Friday, including people without symptoms.
Many of the cases were confirmed in the provincial capital Shijiazhuang. The city has launched mass testing of its more than 10 million residents. Local authorities also told everyone to stay home for at least one week after their PCR tests.
Authorities say similar measures are being taken in the neighboring city of Xingtai, which has some 7 million residents.
China has said that the coronavirus outbreak was basically under control. But authorities are stepping up vigilance as new infections have also been confirmed in the northeastern province of Liaoning.
