We plan for a range of scenarios. Planning for a worse case than you might see is probably a prudent measure. Some of the scenarios look at the facts as we know them, which is the proportion of people who are mildly ill, which is 80%, followed by a 14% or 15% group who's going to be ill enough to go into the hospital, followed by a smaller group, like 6%, who demand ICU care.
Right now it's very difficult to determine the proportion of people who may die from this illness, unfortunately, because the global numbers will change day by day, and we don't know for certain. I think we can assume that this is an outbreak that's very serious.
If you looked at influenza mortalities, it is at a 0.1% case fatality. Right now the best estimate is that it could be just under 1%, depending on which country you're in, whereas a pandemic influenza, the worst one, is going to be 1% to 2%. If this is close enough to a 1% case fatality, it is a very serious situation.
Having said that, we can change the course. We are changing the course by doing all these massive pieces of work that the public health system is—
