The CIA now believes the virus responsible for the COVID-19 pandemic most likely originated from a laboratory.

The intelligence agency says it has a “low confidence” in its new finding, but this is further than it has ever gone in pinpointing the origin of a virus that killed millions worldwide.

China says it's "extremely unlikely" that COVID-19​ came from a lab, after the CIA said it believed​, though with low confidence, that it did, rather than from natural transmission.
