BEIJING — More than 360 people have tested positive in a growing coronavirus outbreak south of Beijing in neighboring Hebei province.

China’s National Health Commission reported Sunday that 69 new cases had been confirmed, including 46 in Hebei.

The outbreak has raised particular concern because of Hebei’s proximity to the nation’s capital. Travel between the two has been restricted, with workers from Hebei having to show proof of employment in Beijing to enter.

Hebei has recorded 183 confirmed cases and an additional 181 asymptomatic cases over the last eight days. China does not include those who test positive but do not show symptoms in its official case count.

Almost all of the cases are in Shijuazhuang, the provincial capital, which is 260 kilometers (160 miles) southwest of Beijing. A handful have also been found in Xingtai. Both cities have conducted mass testing of millions of residents, suspended public transportation and restricted residents to their communities or villages for one week.
