Plague Data

Plague

Plague is an infectious disease of animals and humans caused by a bacterium named Yersinia pestis. People usually get plague from the bite of a rodent flea that is carrying plague bacteria or by handling an infected animal. Although plague is a rare disease, about half of U.S. cases each year occur in New Mexico. Today, modern antibiotics are effective against plague, but if an infected person is not treated promptly, the disease can be life-threatening.
