Tularemia resurfaces in Northern Colorado after dead rabbit discovery

Tularemia has been detected again in Northern Colorado after a dead rabbit was found in a Berthoud neighbourhood. The bacterial disease is not new to Larimer County, where seven human cases have been recorded since 2020. Tularemia spreads to humans in several ways. Bites from infected ticks and deer flies can transmit the bacteria. Direct contact with sick or dead animals, especially rabbits and rodents, also poses a risk. Contaminated soil, water, and plants may carry the infection too.

Early diagnosis is key, as antibiotics can treat the disease effectively. Common symptoms include fever, fatigue, swollen lymph nodes, and skin ulcers. Residents are advised to stay alert for clusters of dead animals—three or more in a two-week period should be reported to local health authorities.

To lower the risk, Dr. Paul Mayer of the Larimer County Department of Health and Environment recommends precautions. These include using EPA-approved insect repellent, checking for ticks after outdoor activities, and keeping children and pets away from wild animals. The department also advises wearing gloves while gardening, using a dust mask when mowing or digging, and always wearing shoes outside. Dead animals should be removed from properties using protective gloves. Health officials stress that tularemia is naturally present in Larimer County and likely exists in other areas too. By following safety measures, residents can reduce their exposure. Reporting unusual animal deaths helps monitor and control the spread of the disease.
