Quotes from the news wire:
We have data for the whole province and also beyond -- looking at data from other neighboring provinces and going back several months... There is a lot of stuff to look at. It's important to be able in the months before [ the outbreak ] to go down to a much lower level, and try to pick up signals, and see was there anything there that we can we could link.
What is important, what would be of great help, is to get hold of the virus before it adapted to humans, before the version we have now. Because then we would better understand how it adapted to humans, how it evolved, in terms of investigations, China has most probably, most likely, all the expertise needed to do these investigations. They have lot of very qualified researchers to that.
