Dr. Robert Redfield, the former director of the US Centers for Disease Control and Prevention, told CNN's Dr. Sanjay Gupta he believes the origin of the Covid-19 pandemic is a lab in China — a controversial theory without evidence.
“If I was to guess, this virus started transmitting somewhere in September, October in Wuhan,” Redfield told Gupta in a clip that aired Friday on CNN New Day. “That's my own feelings. And only opinion. I’m allowed to have opinions now.”
Redfield, a virologist who led the CDC under former President Donald Trump, said he thinks the virus originated inside a lab in China and “escaped,” not necessarily intentionally.
There is no clear evidence to support the “lab leak” theory, although it has played an ongoing role in conspiracies and speculation, including statements from Trump. The World Health Organization has called it "extremely unlikely."
"Now, I am of the point of view that I still think the most likely aetiology of this pathogen in Wuhan was from a laboratory, escaped. The other people don't believe that. That's fine. Science will eventually figure it out. It's not unusual for respiratory pathogens that are being worked on in a laboratory to infect the laboratory worker," Redfield told Gupta.
Redfield’s comments appear in the documentary “COVID WAR: The Pandemic Doctors Speak Out,” which airs Sunday at 9 p.m. ET on CNN.
