As the president of the agency just stated, the World Health Organization declared this “a public health emergency of international concern” and indicated that right now we are in the containment phase. The most effective piece of containment, of course, is at source, in China itself, where you're seeing some of the extraordinary measures that are being taken.
As you move further away from that epicentre, any other border measures are much less effective. Data on public health has shown that many of these are actually not effective at all. We are doing some of those and adding those layers, but each of those layers is not a complete barrier, if you like. We have provided travel health advice from a health perspective to indicate to travellers to avoid the province of Hubei and to limit non-essential travel to the rest of China. That advice is provided to travellers.
Of course, how you protect yourself when you're in China, I think, is very critical. The other aspect is that you're not going to get health care, particularly if you're stuck inside a quarantine zone. That's another reason for saying not to go to Hubei right now. Not necessarily for health reasons but for reasons of safety and security, Global Affairs says you shouldn't go to China.
I think that WHO advises against any kind of travel and trade restrictions, saying that they are inappropriate and could actually cause more harm than good in terms of our global effort to contain. I believe that Canada is taking a balanced and measured approach as it pertains to travel measures at this point.
