COCONINO COUNTY — Health and Human Services (CCHHS) officials received confirmatory test results today, July 11, 2025, and have confirmed that a Coconino County resident has died from pneumonic plague, a severe lung infection caused by the Yersinia pestis bacterium.
The death is not related to a recent report of a prairie dog die-off in the Townsend Winona area, northeast of Flagstaff. This is the first recorded death from Pneumonic plague in Coconino County since 2007 when an individual had an interaction with a dead animal infected with the disease.
“Our hearts go out to the family and friends of the deceased,” said Coconino County Board of Supervisors Chair Patrice Horstman. “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.”
