Western officials, researchers cast doubt on China lab virus leak theory

"Everything I have heard in my 15 years of work with people in that lab has been absolutely normal with what you'd expect from virology labs," said zoologist Peter Daszak, president of EcoHealth Alliance, responding to the rumor that the virus might have come from a lab in Wuhan.

During an interview with CNN's Fareed Zakaria GPS on Sunday, Daszak also clarified that most pandemics originate in animals, usually wildlife, often bats.

"Nobody has the virus from bats that led to COVID-19," said Daszak. "We've not found it yet. We've found close relatives, but it's not the same virus. So, to my mind, it's not a possibility."
