It can get very technical, but on a broader scale, the risk is obviously very high in China. It has 99% of cases and transmissions. We have had, not unexpectedly, some imported cases that are being well managed. What we look at is the likelihood of importation by volume of travellers from an affected area, followed by essentially looking at the impact from its severity but also looking at impact in terms of whether we have the measures to mitigate the impact. It's a balance of all of those things.
Right now, the cases are in China. Very few are exported. Yes, there's human-to-human transmission, but those are generally for close contacts. With regard to the severity of illness, there are some severe cases, but the deaths have occurred in older people with underlying medical conditions. With all of that pulled together, for the general public who have not been to China, the risk is low in Canada.
