Bubonic plague

Bubonic plague is an infectious disease that is believed to have caused several epidemics or pandemics throughout history. Bubonic plague is the most common form of plague, and is characterized by swollen, tender, inflamed lymph glands (called buboes); other forms are Septicemic plague, which occurs when plague bacteria multiply in the blood, and Pneumonic plague, which occurs when the lungs are infected.
