Answer:
The black death came from fleas. Rats in China had these fleas, and they found their way to Europe. The black death spread so easily because a) there was no proper hygiene, b) cities were often crowded and animals would walk around the streets with humans, c) the 'treatments' that doctors had really didn't have anything to do with the black death.
