A resident of Coconino County, Arizona, has died from pneumonic plague, marking the first plague death in the state since 2007. Pneumonic plague, the most deadly form, is rare, with about seven cases annually in the US. While easily treatable with antibiotics, the infection spreads through infected fleas, bodily fluids, or contact with infected animals. Health officials urge caution when handling sick or dead animals.
