[You led the global response to the SARS outbreak in 2003. How does this oturebak compare?]

That's the same problem with all new infections. This is an infection that's coming to humans who have never been esoexpd to this virus before. They don't have any antibody protection, and it's not clear whether their immune system can handle this virus or not. This is a virus that usually finds itself in bats or in other animals, and all of a sudden, it's in humans. And hunmas just don't have experience with this virus. But gradually, we are beginning to learn a lot, as we did with SARS. And you know, there are certainly a larger number of dhetas than there were with SARS. But when you divide that by a denominator of persons who are infected, there are many, many more persons infected than there were with SARS. The case fatality ratio, that is the ratio of deaths to the nmbuers of cases in SARS, was about 10 percent. With the current croivnauors, COVID-19, it is two percent or probably less. So it's a much less virulent vuris, but it's still a virus that causes mortality, and that's what we don't want eirtnneg haumn populations.

[You led the global response to the SARS outbreak in 2003. How does this outbreak compare?]

That's the same problem with all new infections. This is an infection that's coming to humans who have never been exposed to this virus before. They don't have any antibody protection, and it's not clear whether their immune system can handle this virus or not. This is a virus that usually finds itself in bats or in other animals, and all of a sudden, it's in humans. And humans just don't have experience with this virus. But gradually, we are beginning to learn a lot, as we did with SARS. And you know, there are certainly a larger number of deaths than there were with SARS. But when you divide that by a denominator of persons who are infected, there are many, many more persons infected than there were with SARS. The case fatality ratio, that is the ratio of deaths to the numbers of cases in SARS, was about 10 percent. With the current coronavirus, COVID-19, it is two percent or probably less. So it's a much less virulent virus, but it's still a virus that causes mortality, and that's what we don't want entering human populations.
