Pandemic mystery: Scientists focus on COVIDs animal origins – Associated Press

“The lab-leak circumstance gets a lot of attention, you understand, on locations like Twitter,” however “theres no evidence that this virus was in a lab,” stated University of Utah researcher Stephen Goldstein, who with 20 others composed a post in the journal Cell in August laying out evidence for animal origin.Michael Worobey, an evolutionary biologist at the University of Arizona who contributed to the post, had signed a letter with other researchers last spring stating both theories were feasible. That includes the virus that caused the 2003 SARS epidemic, which also has been associated with markets offering live animals in China.Many scientists think wild animals were intermediate hosts for SARS-CoV-2, meaning they were infected with a bat coronavirus that then evolved.”The gold-standard piece of proof for an animal origin” would be an infected animal from there, Goldstein said. ANIMAL THREATSExperts fret the very same sort of animal-to-human transmission of viruses might spark brand-new pandemics– and worsen this one.Since COVID-19 emerged, lots of types of animals have gotten contaminated, including pet canines, cats and ferrets; zoo animals such as big cats, otters and non-human primates; farm-raised mink; and white-tailed deer.Most got the infection from people, according to the U.S. Centers for Disease Control and Prevention, which states that humans can spread it to animals during close contact however that the threat of animals transferring it to individuals is low.Another fear, nevertheless, is that animals could unleash brand-new viral versions.”Around the world, we might have animals possibly breeding these variations even if we get (COVID-19) under control in people,” stated David OConnor, a virology expert at the University of Wisconsin-Madison.
