The unnamed patient was hospitalized and has survived following intravenous antibiotic treatment. Investigation revealed that the family dog became ill with symptoms consistent with plaque a few days prior to the onset of illness in the dog’s owner. The dog has recovered and test results from the dog are pending.

One month ago, a Larimer County teen contracted and died from septicemic plague.

Chaffee County Public and Environmental Health is doing surveillance for rodent die-off and has posted warning signs about plague in the vicinity of the Little Rainbow Trailhead off CR 110.

The bacteria that cause plague, Yersinia pestis, maintain their existence in a cycle involving rodents and their fleas. Plague is a cause of die-offs of rodents and rabbits. When these animals die, fleas leave the carcass to find another host, thus spreading the disease. Most human plague cases result from the bites of infected fleas. Less commonly people are infected by direct contact with fluids or tissues from infected animals including pets.

Many types of animals, such as rock squirrels, wood rats, ground squirrels, prairie dogs, chipmunks, mice, voles, and rabbits can be affected by plague. Wild carnivores and domestic pets can become infected by eating other infected animals.  Cats are particularly susceptible to plague.

Symptoms of plague generally include sudden onset of high fever, muscle pain, malaise, nausea and vomiting, or a general feeling of being ill. Individuals with bubonic plague will develop a large, swollen, painful lymph node, called a bubo, in the area of the flea bite. If the patient is not promptly treated with antibiotics, the plague bacterium can enter the bloodstream (septicemic plague) or lungs (pneumonic plague) causing severe, life-threatening complications. In rare instances people can inhale the bacterium and initially present with pneumonic plague.

There has been 18 confirmed human plague cases in Colorado since 2005.

  4. Hi,
    My name is Corrine I just moved to Colorado Springs in May, 2015
    I have a two year old daughter who I am assuming was bitten by a flea from the family dog. The bite was concerning after recently confirming plague in a mule deer in the area.
    So upon the finding of her bite I had taken her to ER. because no family doctor has been established in the area.
    Upon our arrival I was asked “what illness she was suffering”?
    My simple response was a flea bite with no symptoms.
    After waiting four hours the doctor from Penrose St. Francis Hospital 2222 N. Nevada Ave. Colorado Springs.
    Dr. Birge,Paul came in and examine my daughter only by looking at the bite ONLY looking at her bite he determined that it was no case of the plague or a flea bite at all but Mrsa! So with out any testing he was ordering pharmaceutical drugs to give my two year old who I ashore you only had one simple flea bite after asking why can he not at least swob the infected area and test for any bacteria that might be. He declined and told me that I would never see the plague in my life and he as a 20 year doctor would never see it.
    Instead he sent my daughter home with a script of sulfamethoxazole and told me to follow up with a pediatrician this date of ER. appointment was 07/23/2015
    Here it is 07/26/2015 and the bite is just about gone.
    The fact that this County does have a confirmed plague and the doctor refused to test a child is quite scary considering the boy recently mentioned in the Denver Post whom died of septicemic plague.
    Not knowing how to handle this experience with the ER. Other then wow I wanna go back home!!
