Squirrel tests positive for plague in Colorado


A squirrel has tested positive for bubonic plague in Colorado.

According to health officials, the squirrel is the first case of plague in the city of Morrison, Jefferson County, which is about 27 miles southwest of Denver.

“Plague is an infectious disease caused by the Yersinia pestis bacteria and can be contracted by humans and pets,” wrote public health officials. However, if proper precautions are taken, the risk of contracting the plague is “extremely low,” they said.

Humans can become infected by flea bites or infected animals.

“Cats are highly susceptible to plague and can die if not treated with antibiotics right away. Cats can get plague from flea bites, rodent scratches / bites, or ingestion of a rodent. Dogs are not as susceptible to plague; however, they can collect and transport plague-infected rodent fleas, “authorities wrote.

The public health department advised pet owners to consult a vet if they suspect their pet is ill. Also, pet owners who live near wildlife habitats, such as prairie dog colonies, should ask their vet about flea control.

Plague symptoms can include high fever, chills, headache, and nausea, among other signs, that occur within a week of exposure. However, plague can be treated with antibiotics after early diagnosis.

Anyone experiencing these symptoms should see a doctor.

Jefferson County Public Health recommends the following precautions to protect against plague:

  • Eliminate all sources of food, shelter and access for wild animals around the home.
  • Do not feed wild animals.
  • Keep a yard free of garbage and trash to reduce wildlife habitats.
  • People and pets should avoid contact with sick or dead wild animals or rodents.
  • Use caution when handling sick pets. Have a vet examine sick pets.
  • Talk to your vet about flea and tick control for your pets.
  • Prevent pets from roaming freely outside the home, where they can attack wild animals and bring disease home with them.
