Five Unseen Foes Five Worst Diseases Humans Battled and Overcame

Let us dive into the ominous past when a bacterium named Yersinia pestis brought humanity to its knees. The antagonist of our tale made its terrifying debut as the Black Death in the 14th century. This microbial villain wiped out 60% of Europe's population with its sinister arsenal of infectious tactics. A deadly combination of fleas, rats, and human carriers allowed for its swift, relentless spread across continents.

DNA analysis of ancient remains has helped scientists trace the progression of this ruthless pathogen. Interestingly, our foe evolved over time - while the initial strain was deadly, later mutations were less lethal.
