A resident of northern Arizona has tragically succumbed to pneumonic plague, marking the first such fatality in Coconino County since 2007.

The individual was treated at a Flagstaff emergency room and, despite immediate medical intervention, passed away the same day.

Health officials have confirmed that the cause of death was pneumonic plague, a severe lung infection caused by the Yersinia pestis bacterium.

In a statement, Coconino County Board of Supervisors Chair Patrice Horstman expressed, "Our hearts go out to the family and friends of the deceased. We are keeping them in our thoughts during this difficult time."

Out of respect for the family's privacy, no additional information about the death will be released.

Pneumonic plague is the most serious form of plague, affecting the lungs and capable of human-to-human transmission through respiratory droplets.

Symptoms typically appear within one to eight days after exposure and may include fever, chills, headache, weakness, and muscle pain.

Health officials emphasize that while plague is rare in humans, with an average of seven cases reported annually in the U.S., it remains a serious concern.

Preventative measures include avoiding contact with wild animals, using insect repellent containing 20-30% DEET to prevent flea bites, and ensuring pets are treated with veterinarian-approved flea treatments.

Residents are also advised to report any sudden die-offs of rodents or rabbits to local health departments, as these can indicate the presence of plague in the area.

Early diagnosis and treatment with antibiotics are crucial for managing plague infections effectively.

Anyone experiencing symptoms consistent with plague should seek immediate medical attention.
