Prolonged Field Care Podcast 213: Dengue Fever

In this episode of the PFC Podcast, Dennis speaks with Dr. Ryan Maves, an infectious disease physician, about dengue fever, a significant tropical disease. They discuss the epidemiology, clinical presentation, management, and prevention strategies for dengue, emphasizing the importance of recognizing warning signs and providing supportive care. Dr. Maves shares insights from his extensive experience in tropical medicine, particularly during his time in the Navy and in Peru, where he conducted research on dengue and other vector-borne diseases. The conversation highlights the increasing relevance of dengue in both civilian and military contexts, especially in light of climate change and urbanization.
