__ **The Black Death** __

Scientists testing infected rats

The disease: The Black Death is most commonly believed to have been caused by the bacteria Yersinia pestis, a bubonic(disease of the lymphatic system) and zoonic(adapted to both animals and humans) disease that was and is usually carried by fleas. The infected flea bites its host(commonly a rat) and takes blood which becomes infected, then when the flea latches on to its next victim(a human on the topic of the plague) it regurgitates the blood into the new host's blood stream, infecting them with the disease.

Here are some ways to keep you safe from the disease: You can ether live out in the country because it came from Asia. It was not near the silk road and the rats were not going towards the country. Another way you can prevent the black death is you can quarantine yourself and stay away from everything.
