How was the bubonic plague stopped from spreading during the 14th Century?

In all the places effected by the bubonic plague in the 14th Century, not just Europe, how did the various nations go about ridding the plague? I know it came back plenty of times since the fourteenth century (and in fact, it hit in the 6th and 7th centuries in the form of Justinian's Plague). But, in the end, how did, say, Europe 'get rid' of the plague? And how did the way they got rid of it differ from the way, say, the Arabians or the Chinese got rid of it?
