Researchers used AI to determine which overlooked animals could host a new coronavirus
The study identified a range of mammals that could be sources for new strains
Finding the sources
The researchers used machine learning topredict the relations between 411 coronavirus strains and 876 potential mammal host species.
This helped them identify animals that were most likely to be co-infected with different strains of the virus — which could cause a new one to emerge.
The researchers found at least 11 times more associations between mammal species and coronavirus strains than were previously known.
They also estimate that there are over 40 times more species that can be infected with four or more coronaviruses than have been observed to date.
“Given that coronaviruses frequently undergo recombination when they co-infect a host, and that SARS-CoV-2 is highly infectious to humans, the most immediate threat to public health is recombination of other coronaviruses with SARS-CoV-2,” said study co-lead Dr Marcus Blagrove.
The research suggests there could be 30 times more host species for SARS-CoV-2 recombination than are currently recognized. They include the dromedary camel, African green monkey, and the lesser Asiatic yellow bat.
The researchers note that their results draw on limited data and that there are study biases for certain species. Nonetheless, they believe the findings could help reduce the risk of new coronaviruses spreading to people.
