The first ever Crash Course Lecture! Join us and guest lecturer John Green in the live chat as we learn about the history and science of tuberculosis, its impact on contemporary culture, and how we can help eradicate this curable disease. https://youtu.be/7D-gxaie6UI

Crash Course Lectures are individual long-form videos that dive deep into a topic in a multidisciplinary way. As always at Crash Course, we embrace curiosity. We hope learners of all kinds enjoy these lectures, and that you are inspired to continue learning about the topic even after the video ends!

This lecture was produced thanks to the generosity of the Crash Course audience, including all of you who fund us on Patreon, who’ve purchased Crash Course coins, and who share Crash Course with others. Your support lets us experiment with new formats, cover lesser-known topics, and go deeper than we ever have before. Thank you! Truly, this would not exist without you.
