According to new research, tourists who take selfies with wild mountain gorillas could put the primates in danger of developing Covid-19. According to a press release from the university on Tuesday, scientists from Oxford Brookes University, England, looked at hundreds of Instagram posts from individuals visiting animals in East Africa and noticed that most visitors were close enough to gorillas to transmit viruses and diseases. “The risk of disease transmission between visitors and gorillas is very concerning,” a declaration said by study lead author Gaspard Van Hamme, an alumnus of Oxford Brookes University who began working on the study during his master’s program. “It is vital that we strengthen and enforce tour regulations to ensure gorilla trekking practices do not further threaten these already imperiled great apes.”

Mountain gorillas are listed as endangered, with, according to the release, an estimated 1,063 of them remaining in the wild. They remain in Uganda (Bwindi Impenetrable National Park and Mgahinga Gorilla National Park), the Democratic Republic of Congo (Virunga National Park), and Rwanda (Virunga National Park) (Volcanoes National Park). Researchers looked at 858 images shared under two hashtags on Instagram from 2013-2019 — #gorillatrekking and #gorillatracking, the study said. 86 percent of the number showed individuals within four meters (13.1 feet) of gorillas, and 25 of those pictures showed gorillas being reached by visitors.
