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.

An Eddy County man was confirmed as the first plague case in New Mexico in 2008. The man had the bubonic form of the disease and has recovered. He most likely acquired plague from hunting and skinning rabbits.
Four cats, three dogs, and a rock squirrel from Santa Fe County, two cats from Rio Arriba County, and one dog from Bernalillo County have been confirmed with plague since the beginning of the year. One cat developed pneumonic plague and died; the remaining pets recovered with antibiotic treatment. See press release of July 3, 2008 for more information about plague.
