Based on data coming out of China, about 20% of cases are what they define as severe. That could mean pneumonia. We know that in terms of the number of deaths, there have been just over 130 out of over 6,000 reported cases. We currently cannot estimate the actual case vitality rate. That takes time and the other outbreaks can take weeks, or in fact months, to ascertain. I think the global response has been to treat this as potentially serious. That's where we are at, with about 20%.
