The New Mexico Department of Health has confirmed the state’s first human case of plague in 2026.
Health officials say a woman from Santa Fe County has died from the bacterial disease. The department is now working to contact individuals who may have been in close contact with the woman and is conducting an environmental assessment to determine if there is any ongoing risk.
Plague is caused by bacteria that are commonly found in wild rodents and is typically spread to humans through the bites of infected fleas. It can also be transmitted through direct contact with infected animals, and in rare cases, through respiratory droplets if the lungs are involved.
Symptoms can include sudden fever, chills, weakness, and swollen lymph nodes. Health officials say that with early diagnosis and proper antibiotic treatment, the disease can often be treated effectively.
New Mexico typically reports a small number of cases each year. In 2025, the state recorded three human cases, and one in 2024, which was fatal. Animal cases have also been reported, including several dogs diagnosed this year.
Officials say they will continue monitoring the situation as the investigation moves forward.
