The fleas bit the rats and they had 3 days to pass it on to the humans in London. The peoples will start to bruises, swell up and cough up blood and eventually die! The more they coughed and sneezed the more it spread, it was very over crowded so it spread even faster. Historians believe that there are two ways to how it stopped. T he first way is it was a very cold winter, the second reason is since the Great Fire Of London burnt down most of the buildings which were rat infested
