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 human has died of pneumonic plague in northern Arizona, Coconino County health officials said. The victim sought help at a Flagstaff hospital.

The first pneumonic plague death in Arizona's Coconino County in almost two decades highlights the rare but deadly respiratory disease transmitted mainly by infected fleas.
