A rare form of the bacterial infection linked to the “Black Death” that killed millions in Europe during the 14th century has taken the life of a resident in Arizona.
The afflicted person died in the emergency room of the Flagstaff Medical Center after being diagnosed with pneumonic plague.
On average, the United States reports seven cases of the plague each year.
In most cases, the plague is easily treated with antibiotics.

Per CBS:
A resident of northern Arizona has died from pneumonic plague, health officials said Friday.
Plague is rare to humans, with on average about seven cases reported annually in the U.S., most of them in the western states, according to federal health officials.
The death in Coconino County, which includes Flagstaff, was the first recorded death from pneumonic plague since 2007, local officials said. Further details including the identify of the victim were not released.
“Our hearts go out to the family and friends of the deceased,” said Coconino County Board of Supervisors Chair Patrice Horstman said in a statement. “We are keeping them in our thoughts during this difficult time. Out of respect for the family, no additional information about the death will be released.”
Arizona health officials have signaled that the plague could have originated from prairie dogs.
