Tularemia is a rare but serious bacterial infection caused by Francisella tularensis. It primarily affects wild animals, especially rodents, rabbits, and hares, but can be transmitted to humans. It is most common in rural areas of North America, Europe, and parts of Asia.

Tularemia was first identified in 1911 in ground squirrels in Tulare County, California, from which it derives its name. The causative bacterium, *Francisella tularensis*, was isolated shortly thereafter. Due to its high infectivity and potential for severe illness, it has been studied as a biological warfare agent.
Tularemia is primarily transmitted through the bite of infected ticks or deer flies. It can also spread through direct contact with infected sick or dead animals (e.g., skinning rabbits) or by inhaling contaminated aerosols (e.g., dust from contaminated soil). Ingestion of contaminated food or water is another potential, though less common, route. It is not known to spread from person to person.

Tularemia has been detected in a dead rabbit in Berthoud, Larimer County, Colorado, USA, consistent with the pathogen's known endemic presence in the region and its seasonal summer peak. No associated human cases have been reported with this detection, and the situation does not constitute an outbreak. Ongoing wildlife surveillance and public precautionary measures remain warranted given the elevated risk of outdoor exposure during the summer months.

A 23-year-old previously healthy woman was referred to the outpatient Clinic for Tropical and Travel Medicine, University Hospital Tübingen, in summer 2024. Eleven days earlier, within the local area of Baden-Württemberg, she had found an immobile red squirrel and had attempted to pick it up. The squirrel had bitten the distal phalanx of her right middle finger, causing a puncture wound. The patient had cleansed the wound with povidone-iodine ointment (Betaisodona®) and had received a tetanus booster from her general practitioner (GP). Seven days post-bite, she developed headache, chills and fatigue without measured fever. Another three days later, she noted a painful swelling in the right axilla and inner upper arm. Suspecting tularemia, her GP started oral ciprofloxacin 500 mg twice dail...
