How the PLAGUE Began
Infected fleas were carried into Europe by a species of black rats, that were traveling aboard international trading ships. The rats then got off on port and died where the fleas would then attach themselves onto humans who then got sick. Y. Pestis, commonly known as The Black Plague, would infect the flea buy blocking off its stomach. The flea would then feed more than necessary causing more people and rodents to get infected.
Y. Pestis
Y. Pestis caused three versions of the plague:
- 1. The Bubonic Plague, which was caused by infected flea bites. This plague was usually fallowed by fever and black welts.
- 2. The Pneumonic Plague, a lung infection that forced the victim to cough up blood, and infect other victims this way.
- 3. Septicemic Plague, an infection of the blood that was fatal.
The mortality rate
The Bubonic plague was 30-75%
The Pneumonic plague killed 90-95%
The Septicemic plague killed nearly 100%(there is still no cure for this plague)
The Pneumonic plague killed 90-95%
The Septicemic plague killed nearly 100%(there is still no cure for this plague)
