Beaver in Rocky Mountain National Park tests positive for bacterial disease tularemia

A dead beaver that was recently found at the Lily Lake area in Rocky Mountain National Park has tested positive for tularemia, according to park officials on Wednesday.

Tularemia — also detected in the Lily Lake area on the eastern side of the park in 2015 — is a naturally occurring bacterial disease transmitted by infected insects and ticks to rabbits, hares, muskrats, beavers and other small rodents. Tularemia can also spread to humans and can cause serious clinical symptoms.

People can help prevent infection by using insect repellent, washing hands, and giving wildlife their space.

In humans, tularemia can cause a wide range of symptoms, including fever and chills, joint pain, muscle aches and headaches, dry cough and chest pain and an open sore and swelling at the site of a tick bite or swollen lymph nodes. If someone becomes ill with any of these symptoms within two weeks of being in an affected area, they should seek medical attention and tell their doctor about possible exposure to tularemia. Tularemia can be treated successfully with antibiotics.

Though tularemia is a native disease that occurs naturally, human impacts on the environment can affect wildlife habitats and promote the transmission and spread of diseases such as tularemia.
