Albuquerque Area Reports Second Case of Plague

The New Mexico Department of Health (NMDOH) today reported a case of plague from Bernalillo County, the second case of the year.

The 77-year-old man was hospitalized in Albuquerque and has since been discharged.

NMDOH stated in a media release on September 24, 2025, that there have been no deaths from plague in 2025.

Since 2000, an average of two human plague cases have been reported per year in New Mexico.

According to the U.S. CDC, an average of seven human plague cases are reported each year in the United States.

Plague is a bacterial disease primarily affecting rodents and is typically transmitted to humans through the bites of infected fleas, but can also be transmitted by direct contact with infected animals, including rodents, wildlife, and pets.

"The bacterium that causes plague can be found in wild rodents and their fleas throughout New Mexico," commented Dr. Erin Phipps, state public health veterinarian for the NMDOH.

"Keeping pets on the flea control product recommended by your veterinarian helps protect them and your family."

Symptoms of plague in humans include sudden onset of fever, chills, headache, and weakness. In most cases, there is a painful swelling of the lymph node in the groin, armpit, or neck.

Symptoms of plague in cats and dogs include fever, lethargy, and loss of appetite. There may be a swelling in the lymph node under the jaw.

See your doctor about any unexplained illness you may have involving sudden and severe fever.

With prompt diagnosis and appropriate antibiotic treatment, the fatality rate in people and pets can be significantly reduced. Physicians who suspect plague should promptly report to the NMDOH.

Plague vaccines have been used since the late 19th century; however, their availability remains limited in 2025.
