WHO report on the origins of SARS-CoV-2

A much-anticipated report is expected this week, laying out the findings of a World Health Organization joint mission to China. The report says that animals were likely the source of the early outbreak. Critics say politics has tainted the effort — that the Chinese government limited access. Politics aside, understanding the origins of this pandemic is something that scientists like Dr. Arinjay Banerjee really want to get to the bottom of. Banerjee, who was not part of the mission, speaks with The World’s Carol Hills about why understanding the specific zoonotic origins of this virus is critical, and what that means for future outbreaks.
