Bubonic Plague

The bubonic plague is an infectious disease cause by Yersinia pestis, a rod-shaped bacterium. Man gets infected by this bacteria, through the bite of rat fleas. Before the discovery of antibiotics, bubonic plague used to be an extremely fatal and epidemic disease, whose symptoms are fever, chills, weakness, prostration, diarrhea, and the formation of painful lumps called buboes, which caused by the inflammation of lymph nodes, especially in the axillary and inguinal regions (armpits and groin).
