First Human Plague Case Reported in New Mexico for 2025
The New Mexico Department of Health (NMDOH) has confirmed a human case of plague in 2025, marking a concerning development.
The patient, a 43-year-old man from Valencia County, has been hospitalized but has since been discharged, according to a press release dated August 25th.
Interestingly, the man had recently gone camping in Rio Ariba County before the diagnosis.
This particular plague strain is known to circulate among wildlife throughout the western United States, as mentioned in the report.
Erin Phipps, a public health veterinarian with the NMDOH, noted that this event highlights the serious risks posed by this age-old disease. She emphasized the necessity of community awareness and preventive measures.
The last recorded human case of plague in New Mexico occurred in 2024 involving individuals from Lincoln County.
Plague is a bacterial disease commonly found in rodents and typically spreads to humans through flea bites, as indicated by the NMDOH.
Moreover, humans can contract the disease via direct contact with infected animals, be it wildlife or pets.
Common symptoms include fever, chills, headaches, weakness, and notably painful swelling of lymph nodes in areas like the groin, armpits, and neck. For pets—dogs and cats—symptoms can manifest as swollen lymph nodes under the jaw, coupled with fever, lethargy, and a reduced appetite.
Fortunately, antibiotics can effectively treat the plague, which significantly reduces mortality rates when diagnosed swiftly, according to NMDOH guidance.
To avoid infection, it’s best to steer clear of deceased or diseased rodents and rabbits. Keeping areas tidy, like cleaning up places where rodents might nest and ensuring that hay, trees, and compost heaps are situated away from home, can help. Additionally, using insect repellents while camping or hiking is recommended as another preventive measure.
For those who own pets, NMDOH advises employing suitable flea treatments and seeking veterinary care for sick animals.
If individuals experience unexpected illnesses with sudden, severe fever, they should definitely reach out to a healthcare provider for evaluation.
