The Apache County Public Health Services District has confirmed a human case of plague in a county resident, the first reported locally since 2015.
In a press release issued April 7, health officials said the individual has recovered following appropriate medical care. This marks the first confirmed case in Apache County since 2015, and the fourth case reported since 2006. Officials emphasized that the risk to the general public remains low.
Plague is a rare but serious bacterial infection caused by the bacterium Yersinia pestis. It is most commonly transmitted through the bites of infected fleas that live on rodents such as prairie dogs, squirrels, and rats. In rare instances, it can also spread through direct contact with infected animals.
Health officials are working with partners to assess environmental risks and determine the likely source of exposure. That includes monitoring rodent populations and flea activity, which can indicate increased risk in certain areas.
Apache County has a history of plague activity, including a notable rodent die-off event in 2015—often referred to as a “die-off event”—which signaled active transmission in the environment. Public health officials say such events are closely tracked because they can increase the likelihood of human exposure.
Symptoms of plague typically appear within two to six days and may include sudden fever and chills, headache, muscle aches, fatigue, and swollen, painful lymph nodes, commonly called “buboes.” In more severe cases, the infection can affect the lungs or bloodstream, leading to serious complications.
Officials urge residents who may have been exposed to rodents or fleas and are beginning to experience symptoms to seek medical care promptly. Plague is treatable with antibiotics, particularly when identified early.
The health district is also conducting follow-up measures, including environmental assessments and public education efforts, to reduce the risk of additional cases. There is currently no indication of widespread risk.
Residents are advised to take precautions when outdoors, including avoiding contact with wild rodents and their burrows, using insect repellent, keeping pets free of fleas, and not handling sick or dead animals. Keeping yards clear of debris that may attract rodents can also help reduce risk.
Healthcare providers in the region have been notified and are prepared to evaluate and treat patients if needed. No additional cases have been reported.
