AI could control the transmission of zoonoses such as SARS-CoV-2

An international research team has discovered that humans would transmit their virus to animals more often than previously thought. A study recently published in Ecology Letters described nearly a hundred of thats different. It’s a bit like the SARS-CoV-2 which has spread to some captive animals (zoo lions and tigers) and other wild animals (white-tailed deer).

Gregory Albery, a postdoctoral researcher in the Department of Biology at Georgetown University, and his colleagues found that nearly half of incidents recorded occurred in captive environments like zoos. More than half of the cases identified were cases of human-to-primate transmission. An unsurprising result, because pathogens have an easier time passing from one host to another, and especially because the wild populations of endangered great apes are closely monitored.

What about transmission from animals to humans?

There would be morePathogens in places where researchers spend the most time researching, such as zoos or places near humans.

“This raises questions about what cross-species transmission events we might be missing, and what that might mean not just for public health, but also for the health and conservation of infected species. »

Some data suggest that in to less a case, white-tailed deer have transmitted SARS-CoV-2, the virus responsible for COVID-19, to humans. Many scientists are concerned that there may be new animal reservoirs that would allow the virus to evolve into new ones. news variants.

Nevertheless, Mr. Albery and his colleagues found that a intelligence artificial could be used by scientists to to anticipate species likely to contract the virus.

“The pandemic has given scientists the opportunity to test some predictive tools, and it turns out that we are better prepared than we thought. »

Understanding these inter-species transmissions

The Viral Emergence Research Initiative or Verena team is launching a new study concerning “the science of the host-virus network”. This new area consists of to predict which viruses can infect humans, which animals harbor them, and where, when and why they might emerge.

According to the authors, the biggest problem would be the little knowledge that we have wild animal diseases.

“We monitor SARS-CoV-2 more closely than any other virus on earth, so when contagion occurs, we can catch it. It is even more difficult to assess the risk credibly in other cases where we do not have as much information. »

Fagre explains that thanks to a close and long-term monitoringwe could identify these events of inter-species transmission more rapidly and Act in consequence.
