TED-ED: The past, present and future of the bubonic plague - Sharon N. DeWitte

The Black Death was a devastating epidemic in the 14th century, wiping out a significant portion of the world's population. It was caused by Yersinia pestis, the same bacterium responsible for bubonic plague today. Despite no significant genetic differences between ancient and modern strains, the medieval outbreak was deadlier due to societal factors like malnutrition and poverty. The epidemic led to socioeconomic changes, weakening feudalism and altering the gene pool. Modern antibiotics have reduced the threat, but drug-resistant strains pose new risks. Understanding the Black Death's impact helps prevent future epidemics.
