Wyoming health officials reported yesterday that three domestic cats from Park County have tested positive for Yersinia pestis, the causative agent of the plague.
All three cats lived in Cody, off the South Fork Road. The illness was confirmed in the first pet by the Wyoming State Veterinary Laboratory in Laramie on April 12, with confirmation of the third on April 20.
No human plague cases have been reported.
“Plague is a serious bacterial infection that can be deadly for pets and for people if not treated promptly with antibiotics,” said Dr. Karl Musgrave, state public health veterinarian with the Wyoming Department of Health (WDH).
“The disease can be transmitted to humans from ill animals and by fleas coming from infected animals. We want people to know of the potential threat in the area the cats were from as well as across the state. Dogs can also become ill and transmit the disease.”
“While the disease is rare in humans, it’s safe to assume that the risk for plague exists all around Wyoming,” Musgrave said. Six human cases of plague have been confirmed in Wyoming since 1978 with the last one reported in 2008. There are an average of seven human cases across the nation each year.
Plague symptoms in animals can include enlarged lymph glands; swelling in the neck, face or around the ears; fever; chills; lack of energy; coughing; vomiting; diarrhea and dehydration. Ill animals should be taken to a veterinarian.
Plague symptoms in people can include fever, swollen and tender lymph glands, extreme exhaustion, headache, chills, coughing, difficulty breathing, abdominal pain, vomiting and diarrhea. People who are ill should seek professional medical attention.
