Nearly two years into the COVID-19 pandemic, the origins of the virus remain shrouded in mystery. Most scientists believe the virus jumped from bats to humans, either directly or through another animal. Others theorize it escaped from a lab.http://apne.ws/cq2MZmd

Michael Worobey, a University of Arizona evolutionary biologist, first signed a letter saying both theories were viable. But he said he was always more supportive of the animal hypothesis, and his own and others' research has made him even more confident.http://apne.ws/dPWcqJR

Many researchers believe wild animals were intermediate hosts for SARS-CoV-2, the virus that causes COVID-19, meaning they were infected with a bat coronavirus that evolved — and then was transmitted to humans. http://apne.ws/KvN6HIa pic.twitter.com/I4BhljWahR

Experts worry that the same sort of animal-to-human transmission of viruses could worsen this pandemic or spark new ones. Failing to fully investigate the animal origins, scientists wrote in the journal Cell, would “leave the world vulnerable.” http://apne.ws/r58fYhR pic.twitter.com/opUTEV3Dh8

Another fear is that the virus could incubate in animals and then unleash new variants. “We’re probably not going to do a big giraffe immunization program any time soon," said David O’Connor, a virology expert at the University of Wisconsin-Madison.http://apne.ws/IG5MSYM

sure, but its a lot more likely to jump from a bat to some livestock and from livestock to humans
