Episode 47 Schistosomiasis: A Snail’s Pace

It’s back to your regularly scheduled programming this week with an episode on schistosomiasis (aka bilharzia), that scourge both ancient and modern. We kick off the episode by walking you through the amazingly complex life cycle of these blood flukes and the myriad of symptoms they and their eggs can cause, including a “check out the reproductive output on this one!” moment.  We then trace its early appearances in mummies (of course) and ancient writings, following that up with an overview of how imperialism drove the field of tropical medicine in its early days. To wrap up this wormy episode, we discuss the current, staggering numbers on schisto around the globe.
