The Black Death
How the Plague Arrived Estimated to be some time during the summer of 1348 in Europe. By the fall it spread throughout the southwest of Europe. By 1349 it had reached England. England was completely infected by By the end of that year, nearly 2 ½ million people were dead. –An estimated 1/3 of Europe's population or 25,000,000 people!
Where did the Black Death come from?
Symptoms of the Plague
What caused the Plague? The Oriental Rat Flea
How was the Plague Transmitted? Spread by fleas that lived on black rats. The fleas sucked the rat’s blood which was infected with the plague. When the rats died, the fleas moved onto humans.
Forms of the Plague: Bubonic The bubonic plague was the most commonly seen form of the Black Death. The mortality rate was 30-75%. The symptoms were enlarged and inflamed lymph nodes (around arm pits, neck and groin). Victims were subject to headaches, nausea, aching joints, fever of degrees, vomiting, and a general feeling of illness. Symptoms took from 1-7 days to appear.
Forms of the Plague: Pneumonic The pneumonic plague was the second most commonly seen form of the Black Death. The mortality rate for the pneumonic plague was 90-95% (if treated today the mortality rate would be 5-10%). The pneumonic plague infected the lungs. Symptoms included slimy sputum tinted with blood. –Sputum is saliva mixed with mucus exerted from the respiratory system. As the disease progressed, the sputum became free flowing and bright red. Symptoms took 1-7 days to appear.
Forms of the Plague: Septicemic The Septicemic plague was the most rare form of all. The mortality was close to 100% (even today there is no treatment). Symptoms were a high fever and skin turning deep shades of purple. The black death got its name from the deep purple, almost black discoloration. Victims usually died the same day symptoms appeared. In some cities, as many as 800 people died every day.
How did they cure it? Medieval people did not know that the germs caused the disease. They also did not know that it was spread by rats and fleas. They had a superstitions believe that their bodies must be poisoned.
Crazy Cure #1 The swelling should be softened with figs and cooked onions. The onions were mixed with yeast and butter. Then they opened the swelling with a knife. Did it work?
Crazy Cure #2 Take a live frog and put its belly on the plague sore. The frog would swell up and burst. Keep doing this until the frogs stop bursting. Some felt that a toad would work better then a frog. Did it work?
