First Human Plague Case of 2025 Reported in New Mexico

The New Mexico Department of Health (NMDOH) has announced a confirmed case of human plague in a 43-year-old resident from Valencia County. This individual had recently gone camping in Rio Ariba County.

Amid several outbreaks of bacterial infections, there have been five reported deaths in major cities. The plague, which typically circulates among wildlife in the western United States, serves as a reminder of the continuing threat posed by this age-old disease. Erin Phipps, a public health veterinarian with NMDOH, emphasized the importance of raising community awareness to prevent further spread of the infection.

The last human plague case in New Mexico was recorded in 2024, affecting residents in Lincoln County. According to NMDOH, the plague is a bacterial disease primarily affecting rodents and is spread to humans usually through bites from infected fleas. However, the disease can also be transmitted through direct contact with infected animals, including pets and wildlife.

Symptoms in humans can range from fever, chills, headaches, and weakness to painful swelling of lymph nodes, particularly in the groin, armpits, and neck. For pets like cats and dogs, symptoms can include swollen lymph nodes under the jaw, along with fever, lethargy, and loss of appetite.

Fortunately, plague can be treated with antibiotics, which significantly lowers the fatality rate when diagnosed quickly. Preventative measures include avoiding contact with sick or dead rodents, cleaning up areas where rodents might nest, and keeping hay, trees, and compost away from living spaces.

When outdoors, it’s advisable to apply insect repellent while camping or hiking. For pet owners, using flea prevention methods and consulting a veterinarian for sick pets is highly recommended. If someone experiences unexpected illnesses with severe fever, it’s essential to seek medical attention.

The NMDOH continues to monitor the situation and urges the public to stay informed and vigilant.
