The cast of Love Island USA got into a wild conversation on the June 10 episode, when Cierra claimed that STDs came from humans having intercourse with animals<\/p>\n<\/li>\n

None of the claims are true; and while koalas are infected with chlamydia, it’s a different strain than humans<\/p>\n<\/li>\n<\/ul>\n
Love Island USA\u2019<\/a>s Cierra made some wild claims about the origins of STDs, with one conversation focusing specifically on a cuddly Australian animal.<\/p>\n During the June 10 episode of the Hulu<\/a> hit, Cierra announced, \u201cDid you know STDs only formed because men couldn’t keep their d—- outside of animals \u2014 like, chlamydia is from koalas?\u201d<\/p>\n The truth is that yes, a large portion of koalas are infected with chlamydia. However, as Tufts University<\/a> points out, it\u2019s a different strain from the type that infects humans.<\/p>\n Koalas having chlamydia is not a unique occurrence in the animal kingdom: As research from UC Davis College of Biological Sciences<\/a> points out, fish, birds, reptiles \u2014 and even amoebas \u2014 can get infected with the bacteria. And per NPR<\/a>, koalas were likely originally infected by contact with feces from other infected animals \u2014 and then the marsupials spread it from mother to offspring, and to each other.<\/p>\n Ben Symons\/Peacock<\/p>\n The cast of ‘Love Island USA’<\/p>\n That is just a theory though: \u201cWe know surprisingly little about the evolutionary origins of Chlamydia trachomatis,<\/a>\u201d the primary strain that causes the disease in humans, according to research from the Annals of the New York Academy of Sciences<\/a>. Koalas, on the other hand, are sickened by Chlamydia pecorum, Wildlife Health Australia<\/a> says, which is the main cause of chlamydial infection and disease in the species.<\/p>\n And while koalas spreading a sexually transmitted disease might seem like a punchline, BBC<\/a> reports that it\u2019s an epidemic killing off Australia\u2019s cuddly creatures, with populations declining as much as 80% in some areas.<\/p>\n Lisa Maree Williams\/Getty<\/p>\n Stock image of a koala in a tree.<\/p>\n Cierra also claimed that gonorrhea came from cows; in reality, it’s one of the oldest sexually transmitted diseases. It’s been around forever. According to the Journal of Skin and Sexually Transmitted Diseases<\/a>, “there is some conflict of opinion regarding its exact origin, but according to the general consensus, the disease has been present from the ancient times,” as far back as 2600 BC.<\/p>\n As for her statement that Christopher Columbus had sex \u201cwith, like, a f—— manatee”? His claims of seeing mermaids have long been chalked up to manatee sightings \u2014 and from what Columbus wrote<\/a> of these mermaids\/manatees, he found them, well, unappealing. Therefore, JaNa from the sixth season of Love Island likely had the best answer to that: \u201cNo response is the best response.\u201d (Or as Leah put it, \u201csit here mute as f—-.\u201d)<\/p>\n On a Facebook fan page<\/a> for the show, one commenter wrote, \u201cI\u2019m a scientist and when she started her rant I immediately died laughing. I think she heard that on TikTok and just repeated it.\u201d<\/p>\n Never miss a story \u2014 sign up for\u00a0PEOPLE’s free daily newsletter<\/a>\u00a0to stay up-to-date on the best of what PEOPLE has to offer, from celebrity news to compelling human interest stories.<\/strong><\/p>\n Love\u00a0Island USA\u00a0airs daily, except Wednesdays, at 9 p.m. ET on Peacock.<\/p>\n![\"\u00a0Ben](\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/06\/536f7daf023f64c252e6b5765ddb890e.jpeg\"\/)
