The World Health Organization confirmed on Wednesday that Chinese authorities believe a new coronavirus—from the family that produced SARS and MERS—may be the cause of mysterious pneumonia cases in the city of Wuhan.

The Chinese government has not yet publicly stated that a coronavirus is the cause of the illness, which has infected at least 59 people. But the Wall Street Journal reported that was the case earlier Wednesday, citing unnamed sources.
