An Arizona resident has died from the plague as officials were probing whether a prairie dog die-off in the area was also tied to the lethal illness.

The Arizona Public Health Association is advising the public that there is no need to worry about the plague, despite one person in Flagstaff dying from the disease.

A person in northern Arizona died from bubonic (pneumonic) plague, marking Coconino County's first death from the disease since 2007.
