In brief: Lots
The hallmark of bubonic disease is the bubo, an extremely painful infected lymph node draining the area where the infected flea fed on the person.
Pneumonic plague, the only transmissible form of the infection, can occur from spread of the bubonic stage through the bloodstream or be acquired airborne from someone else with pneumonic plague.

In brief: Lungs / lymph nodes
The plague is usually bubonic (one catches it from being bit by infected fleas or rodents, and the bacteria infects one's lymph nodes) or pneumonic (one catches it by breathing infected moisture droplets exhaled, sneezed, or coughed out by an infected person or animal, and the bacteria infects one's lungs).
