"The 2019 novel coronavirus epidemic that started in Wuhan, may be - it is not a prediction, but it is in preparation, as a precautionary principle, as a precautionary principle - we have to be prepared that this particular epidemic may be about to be about to become a global epidemic. This is not a certainty by any stretch of the imagination, but there is a 'not weak', or that is 'not insubstantial' probability that this might happen, and therefore we must prepare better for it."

Public health experts in Hong Kong warned on Monday that there could be thousands more carriers of a new virus from China, despite sweeping efforts to contain the disease.
Chinese health authorities say the new virus has infected 2,744 people and killed 80 as of midnight Sunday.
Analysis of data, according to Professor Gabriel Leung, Dean of Medicine at the University of Hong Kong, suggests there could actually be up 26,000 people infected with the new coronavirus.
And on top of that, there could have been up to 44,000 people incubating the virus.
Leung warned that quarantine and travel control measures implemented so far might not have made a difference to the spread of the virus, and said precautionary preparations to deal with a global epidemic had to be stepped up.
The virus is from the coronavirus family that includes the common cold but also more severe illnesses like SARS and Middle East Respiratory Syndrome.
The new virus causes cold- and flu-like symptoms, including cough and fever, and in more severe cases, shortness of breath and pneumonia.
