Some communities were kind of left alone from the plague and that's probably because they weren't along different trade routes, they weren't exposed in the same ways, or maybe they had different customs that are going to keep them away from the plague. But you can see from the map that I've been showing you, the plague in a very short period of time, in less than a 10 year period, it's going to do its dirty deed. And it's also important to say that it's going to be cyclical in nature. In the winter, the fleas are going to die. So it's not going to have the same effect across Europe in the winter, but it's going to reoccur during this 8 year period every spring and then it's going to do its havoc. And in some cities they lost 20 or 30 percent of their population. Other cities lost up to 70 or 80 percent of their population.
