The Bubonic plague has symptoms similar to the flu, so originally it was treated as a flu. As time passed and physical symptoms appeared (buboes, blackening of tissue and petechiae) it was determined that it was a new virus which old medicine wasn’t advanced enough for. Physicians were forced to advance their forms of medical treatments, keeping some -such as isolation of the infected- and creating more antibiotics rather than mixed herbs that were believed to help. As old remedies, profit remedies, prayer, and many superstitious forms of treatment were ruled out, things became serious. As a demand for a cure rose, so did demand for doctors. Soon, sulfadiazine was created and had some success. It is still used today with appropriate antibiotics. Other effective treatments that were put into effect were: isolation, education on hygiene, managing rat control, sanitary clothes and face masks to cleanse the air which evolutionized to what doctors presently wear. Plague doctors, commonly coming from a church, have turned into modern doctors who attend medical school. Since this took part during the scientific revolution, a big part of this turning point in history was the battle of science vs. faith; wether the people would let reason rule them, or a bunch of a hocus pocus. Reason won, cures were made, people lived. It's still seen today because of unsanitary conditions around different parts of the globe. There is travel all around the world, causing it to still travel out of unsanitary places.
