This week, Aebhric O'Kelly talks with Jason Jarvis about the operational importance of helminths. Takeaways Tropical medicine focuses on helping people in tropical areas with high rates of parasitic worms and tropical diseases. Parasitic worms are classified into species, including Annelida, Nematodes, and Platyhelminths. Worm infestations are more common in developing countries and rural areas. Diagnosing and treating worm infestations are crucial, especially in remote and austere environments. Various worms, such as pinworms, filariasis, schistosomiasis, and tapeworms, can cause significant health problems. Prevention measures, such as avoiding contaminated food and water, are essential in reducing the risk of worm infestations. Ask patients about their travel history and potential exposure to parasitic worms Different species of trematodes have other risk factors and manifestations Diseases and non-battle injuries (DNBI) can have a significant impact in military settings Climate change is contributing to the spread of tropical diseases in new areas   Chapters 00:00 Introduction and Background 02:24 Classification of Parasitic Worms 07:53 Prevalence of Worm Infections 24:39 Prevention and Conclusion 34:50 The Importance of Travel History 37:23 The Role of Recent Travel in Diagnosis 45:57 Diseases and Non-Battle Injuries (DNBI) in Military Settings 49:38 Climate Change and the Spread of Tropical Diseases   Sound Bites "I enjoy having a microscope and little friends to look at." "Approximately four billion people in the world are infected with one type of helminth or another." "Many of these roundworms and helminths cause problems we'll see as medics." "We've got five species of trematodes, five different species of schistosomes that are clinically important to us in human medicine." "When doing a clinical workup, it's important that we ask our patients where they have been?" "The sample is great and universal, but that R is vastly important for recent travel."
