Plague

Plague is a serious bacterial infection that’s transmitted primarily by fleas. The organism that causes plague, Yersinia pestis, lives in small rodents found most commonly in rural and semirural areas of Africa, Asia and the United States. The organism is transmitted to humans who are bitten by fleas that have fed on infected rodents or by humans handling infected animals. Plague is divided into three main types bubonic, septicemic and pneumonic depending on which part of your body is involved. Signs and symptoms vary depending on the type of plague.
