() A resident in Northern Arizona has died from the pneumonic plague, the first person to be killed by the lung infection in the United States since 2007.

According to NBC News, officials confirmed the Coconino County woman’s death but did not yet have any other information to share.

The unidentified individual took themself to the Flagstaff Medical Center Emergency Department and died on the same day despite resuscitation attempts.

The severe lung infection occurs when a person inhales infectious droplets coughed into the air from an infected animal or person, according to the CDC.

This is the only way it can spread between humans.

Unlike the bubonic and septicemic plagues, the pneumonic plague occurs in the lungs and does not cause the skin to turn black, blue or swell in the form of lymph nodes.

The CDC says symptoms can include fever, headache, rapid onset of pneumonia, chest pain, bloody mucus and weakness.
