Spread though European Cargo ships and travelers Historical events • In October of 1347, Italian cargo ships returned from the Black Sea.
When the ships docked in Sicily, many on board were already dying of plague. • There was a serious labor shortage all over Europe.

This led workers to demand higher wages.

By the end of the 1300s peasant revolts broke out in England, France, Belgium and Italy. • The following August, the plague had spread as far as England, people called it "The Black Death" because of black discoloration.
• Each spring, the plague attacked.
After five years 25 million people were killed--one-third of Europe's population! Isolate patient and begin antibiotic therapy. Antibiotics include:

• Gentamycin

• Streptomycin

No plague vaccine is available yet. TREATMENT Statistics Over 80% of United States plague cases have been the bubonic form (1–17 cases per year).

50% of cases occur in people ages 12–45.

In the pre–antibiotic era (1900–1941), 66% of those infected died.

Since antibiotics the death rate has decreased to 16% Biology of the plague DNA
