Scientists who examined previously unavailable genetic data said they found suggestions the COVID\u002D19 pandemic originated from animals.
Mark Woolhouse, an infectious diseases expert at the University of Edinburgh, said it will be crucial to see how the genetic sequences from the raccoon dogs match up to what’s known about the historic evolution of the COVID-19 virus.
After a weeks-long visit to China to study the pandemic’s origins, WHO released a report in 2021 concluding that COVID most probably jumped into humans from animals, dismissing the possibility of a lab origin as “extremely unlikely.” In recent months, WHO director Tedros has said all hypotheses remained on the table, while he and senior officials pleaded with China to share more data about their COVID-19 research.
The paper did not mention that animal genetic material was found in samples that tested positive for COVID-19, and the authors didn’t upload the raw data until March. Gao Fu, the former head of the China CDC and lead author of the paper, didn’t immediately respond to an email requesting comment.
