More than 360 people have tested positive in a growing Covid-19 outbreak south of Beijing in neighbouring Hebei province, AP reports.

China’s National Health Commission reported that 69 new cases had been confirmed in the latest 24-hour period, 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 the city.

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.
