A squirrel tested positive for bubonic plague in Morrison, Colorado, last week. Unusual in squirrels, plague caused by the bacteria Yersinia pestis is found in rodents and their associated fleas throughout the Western U.S.
The report is a reminder for the growing number of people choosing camping in western U.S. parks for summer vacations and trips, regardless of their state of origin.
Yersinia pestis is maintained in the environment in a natural cycle between susceptible rodent species and their associated fleas. Commonly affected rodent species include ground squirrels and wood rats, as well as prairie dogs.
Cats are highly susceptible to plague. Dogs are not, though they can pick up and carry plague-infected fleas, the health department said, adding that pet owners who suspect their pet might be infected should consult a veterinarian. Plague can be treated with antibiotics if diagnosed close to onset.

- Eliminate sources of food, shelter and access for wild animals around the home.
- Don’t feed wild animals.
- Reduce litter and trash in your yard.
- Avoid contact with sick or dead animals.
- Use precaution when handling sick pets.
- Use flea and tick control for your pets.
- Keep pets from roaming freely outside the home.
