Bats that inhabit China’s southern and southwestern border regions harbor other types of coronaviruses that already have the ability to pass to humans, Chinese scientists warn.
The National Academy of Medicine and the Veterinary Academy of France. These viruses, including close relatives to SARS-CoV-2, are likely circulating in the wild beyond China, he added.
The natural reservoir of SARS-CoV-2 is currently believed to be bats, but experts have pointed out that the virus was transmitted to another animal, which served as an intermediate host before reaching humans.
At the moment it is also not clear how long the virus could have been circulating in that animal or in humans before it was detected late last year. According to Shi, SARS-CoV-2 could have been in one or the other « for a long time. »
This view is supported by Professor Edward Holmes, a virologist at the University of Sydney, who did not participate in the seminar, but thinks that the coronavirus could have been in an intermediate host for a long time, and perhaps even humans for a few months. before it was reported.
