I am not convinced about that, I think we should continue to investigate what went on in China until we continue to find out to the best of our ability what happened, certainly, the people who investigated it say it likely was the emergence from an animal reservoir that then infected individuals, but it could have been something else, and we need to find that out. So, you know, that's the reason why I said I'm perfectly in favor of any investigation that looks into the origin of the virus.
