What is plague?
Plague is an infectious disease found in some small mammals and their fleas. People can contract plague if they are in bitten by infected fleas, and develop the bubonic form of plague. Sometimes bubonic plague progresses to pneumonic plague, when the bacteria reaches the lungs. Person-to-person transmission is possible through the inhalation of infected respiratory droplets of a person who has pneumonic plague. Common antibiotics are efficient to cure plague, if they are delivered very early, because the course of the disease is usually rapid.
