People in China should wear masks, socially distance and stay home if unwell amid an outbreak of a mystery respiratory illness, global health chiefs have warned.

Cases of 'undiagnosed pneumonia' have been detected at hospitals in Beijing and in Liaoning, a province 500 miles northeast of the capital.

Health facilities are 'overwhelmed with sick children' and classes are on the verge of being suspended according to local news reports.

Infected children are presenting with lung inflammation and a high fever, but not a cough or other symptoms that signal flu, RSV or another respiratory illnesses.
