"After traveling to Wuhan, China, a team of researchers from the World Health Organization is readying a preliminary report on the origins of the coronavirus.
Wuhan is where the virus was first reported in December 2019.
The WHO team's main public conclusion so far is that it's "extremely unlikely" that the virus originated in a lab in Wuhan. The scientists think the virus most likely started in bats, then jumped to other animals, then to humans.
Dutch virologist Marion Koopmans was part of that team that "reconstructed every step in that initial outbreak" in two weeks of investigation."
