SANTA FE - A Santa Fe County woman has died from plague, marking New Mexico’s first human case of the disease in 2026, the New Mexico Department of Health announced Thursday.

The Department of Health said it has contacted the woman’s close contacts and will conduct an environmental assessment to determine any ongoing risk and confirm that no other close contacts have symptoms consistent with plague.

“We extend our heartfelt condolences to the friends and family of the woman who passed away due to plague,” said Erin Phipps, state public health veterinarian for NMDOH. “This tragedy emphasizes the need for heightened community awareness and for taking measures to prevent plague infections.”

Plague is a bacterial disease carried by rodents and found throughout much of the western United States. It is generally transmitted to humans through bites from infected fleas carried by wild rodents or household pets. It can also spread through direct contact with infected animals. People with plague in their lungs can transmit the disease through coughing, according to NMDOH.

Symptoms in humans include sudden fever, chills, headache and weakness. Some people may also develop painful swelling of lymph nodes in the groin, armpit or neck. Physicians who suspect plague are asked to promptly report cases to NMDOH.

The department said prompt diagnosis and appropriate antibiotic treatment can greatly reduce the fatality rate in people and pets.

To reduce the risk of plague, NMDOH recommends avoiding sick or dead rodents and rabbits, as well as their nests and burrows. The department also recommends clearing areas near homes where rodents may live, including woodpiles, brush piles, junk and abandoned vehicles.

People should use insect repellent while hiking, camping or working outdoors. Products containing DEET can be applied to skin and clothing, while products containing permethrin can be applied to clothing.

Pet owners should talk to a veterinarian about appropriate flea control products, because not all products are safe for cats, dogs and children. Sick pets should be examined promptly by a veterinarian.

New Mexico recorded three human plague cases in 2025 and one in 2024, which was fatal. Three dogs have been diagnosed with plague in 2026. In 2025, one cat and four dogs were confirmed to have plague.
