The Bubonic Plague 1347-1352
In the early 1347 an outbreak of deadly Bubonic plague occurred in China. The Bubonic plague mainly affects black rats, but fleas can transmit the disease to people. Once people are infected, they infect others very rapidly. Plague causes fever and a painful swelling of the lymph glands called buboes, which is how it gets its name. The disease also causes spots on the skin that are red at first and then turn black.
