Dead Rabbit Confirms Tularemia in Northern Colorado
10 Jun
Summary
- Tularemia bacteria found in a dead rabbit in Berthoud.
- Rare bacterial infection can spread from wildlife to humans.
- Seven human cases reported in Larimer County since 2020.

A dead rabbit discovered in a Berthoud neighborhood has confirmed the presence of tularemia bacteria in Northern Colorado. Health officials identified the bacteria, noting that tularemia is endemic to Larimer County and likely present in other areas. This rare but potentially serious bacterial infection is found in local wildlife, particularly rabbits and rodents.
Tularemia can transmit to humans through tick or fly bites, direct contact with infected animals, or contaminated soil and water. Symptoms include fever, fatigue, swollen lymph nodes, and skin ulcers, but early antibiotic treatment is effective. Since 2020, Larimer County has recorded seven human cases of tularemia. Officials advise using insect repellent, checking for ticks, keeping pets and children away from wild animals, and wearing gloves when handling dead wildlife.
