  1. God’s wrath or self inflicted disease? The Plague

  2. Types of Plague • Bubonic – The most Common - bacteria infect the lymph system and become inflamed • Within two to six days of exposure to the plague bacteria, flu-like symptoms may develop • Septicemic - occurs when plague bacteria multiply in the blood. It is contracted in the same way as bubonic plague • Pneumonic plague is the most serious type of plague, and it occurs when Yersiniapestis bacteria infect the lungs and cause pneumonia. • Within one to three days of exposure to airborne droplets of pneumonic plague, symptoms can occur

  3. Causes • Medieval Europeans viewed the plague as God’s punishment • Actual Cause = Rats along trade and shipping routes were carrying bacteria-infected fleas that spread the disease

  4. Scope • Between 1348 – 1350 AD – nearly 25 million Europeans died (1/3 of pop.) • Began in China and spread throughout Asia and Europe following trade routes

  5. Result • As death increased, production declined, and price and wages rose • Creates wage laws • Sparks peasant and worker uprisings

  6. Ring around the Rosie • Ring around the Rosy • One of the first visible signs of infection were red rings surrounding a rosy bump, all over the victim's body. • Pocket full of Posy • A common belief of the time was that the plague was borne on "foul air." The rationale was that people could protect themselves from the bad air by keeping their local air smelling sweet. That, and it also helped them deal with the smell of death... • On the other hand, another sign of infection was the foul stench that would begin to emanate from the victim's body as their lymph system began filling with blood. Those still mobile endeavored to mask their stench and avoid detection by carrying flowers on their person. • Ashes, Ashes, • In the terminal phases of the disease, victims would be hemorrhaging internally, sometimes triggering sneezing as it irritated the breathing passages. "Ashes" is a child's approximation of a paroxysm of sneezing. In this weakened state, a victim could, and often did, sneeze their lungs out. Messy... • We all Fall Down • By now, this one should need little explanation...

  7. Plague Today? • Occasionally occurs in developing areas • Why? • Poor sanitation and cleanliness • Vaccines have isolated plague outbreaks and reduced impact • Pics next slide – Cover your eyes for the weak stomachs
