Scientists investigating the origins of COVID-19 have identified a shortlist of animals that may have played a role in transmitting the virus to humans. By analyzing genetic material collected from the Chinese market where the initial outbreak was detected, researchers have pointed to racoon dogs, civet cats, and bamboo rats as the most likely suspects. It is believed that infected animals were introduced to the Wuhan market in late November 2019, setting off the global pandemic.
The study's authors have determined specific sub-populations of animals that could have passed the coronavirus to humans. This information could aid in identifying the natural reservoir of the virus and potentially tracing its source. For instance, the genetic analysis revealed that the racoon dogs at the market belonged to a sub-species more commonly found in southern China, offering clues about their origin and distribution.
