Coronavirus threatens endangered gorillas, chimps, and orangutans

The coronavirus almost certainly originated in another species before jumping to humans (perhaps infecting a third party species in between), but new research is suggesting that humans could also play the role of vector, National Geographic reports.

A new study led by Harris Lewin, a professor of ecology and evolution at University of California, Davis, found that humans could potentially spread the virus to wild animals, and they probably already have among animals in captivity. For example, Lewin said it's likely lions and tigers that contracted the virus at the Bronx Zoo in New York were infected by human zookeepers.

That could put endangered species — especially close human relatives like the western lowland gorilla, the Sumatran orangutan, chimpanzees, and bonobos — at high risk of a COVID-19 outbreak, especially in places where wild animals are more likely to come into close contact with humans, Lewin told Nat Geo.

Lewin's co-author Klaus-Peter Koepfli singled out Africa's eastern gorilla as another high-risk species because the fewer than 5,000 remaining individuals live in close-knit family groups, making them more vulnerable to their own pandemic.

The good news is there's no evidence the virus is spreading among wild animal populations, and the animals that have been infected in experimental settings have mostly exhibited mild cases. But the risk remains, so Koepfli and Lewin are calling for a focus on preventative methods such as national park staffers getting regularly tested to mitigate the threat.
