Pneumonic plague is both “the least common and most dangerous type of plague,” according to the Cleveland Clinic.

A resident of Arizona has died from pneumonic plague, health officials confirmed on Friday. This was the first recorded death from the disease in the county since 2007, Coconino County Health and Human Services reported. In that case, a person had an interaction with a dead animal infected with the disease.

Officials said the resident died from pneumonic plague, a severe lung infection. The risk to the public remains low.
