Q&A: How worried should we be about the novel coronavirus outbreak?

The novel coronavirus that emerged in the central Chinese city of Wuhan late last year has now caused cases in two neighbouring countries.
Earlier this week, Thai authorities quarantined a Chinese traveller and later confirmed the virus — the first time it has been detected outside China.
And on Thursday, Japan confirmed that a man in his 30s in the Kanagawa prefecture near Tokyo tested positive for the virus.
At least 41 cases of the coronavirus have been reported so far, including two deaths in Wuhan — a 61-year-old man who died from pneumonia and a 69-year-old man who was admitted to hospital with abnormal renal function and severe damage to multiple organs.
