Snakebites and Travellers: Myths, Facts, and First Aid

The World Health Organization (WHO) estimates that 5 million snakebites occur each year, with between 81,000 and 138,000 deaths. A fear of snakes is common. It doesn’t help that snakes have long been cast as villains: In Raiders of the Lost Ark, a deadly cobra lurks in an ancient Egyptian temple. In Greek mythology, Medusa's snake mane is her ultimate weapon. And in real life, White Lotus star Walton Goggins recently revealed he was bitten by a snake while filming in Thailand. It’s no surprise that travellers worry about snakebite. So in the 10th episode of Travel Unravelled, we’re exploring how to minimize the risk of envenomation—and providing some tips for travellers and clinicians in the event that they do encounter a bite from a venomous serpent. Here, the Travel Unravelled team of Dr. Albie de Frey, Dr. Sarah McGuinness and Dr. Aisha Khatib benefit from the perspectives of renowned experts Professor David Warrell, the founding director of the Centre for Tropical Medicine at Oxford University, UK and Dr. Bart Currie, leader of the Tropical and Emerging Infectious Diseases team at the Menzies School of Health Research in Darwin, Australia. How do you determine snakebite risk at your travel destination? What can you do to minimize snakebite risk? What should you do if you get bitten by a snake? Takeaways that our experts explore include: The importance of immobilisation and getting to medical care quickly The value of a photo of the snake, if safe to obtain The fact that not all snakebite victims require antivenom And that clinical assessment and observation are crucial in early hospital management LINKS Watch the World Health Organization’s Science in 5 - Snakebites: Life saving facts    • WHO’s Science in 5 - Snakebites: Life savi...   This GeoSentinel analysis provides lots of information about travellers’ exposures to animals around the world—including snakes. https://pubmed.ncbi.nlm.nih.gov/31993...
