1. A 16-year-old boy presents with a skin ulcer on the dorsum of his hand and swollen glands in the proximal axilla. He works as a camp counselor in South Dakota, leading nature walks and teaching the children to care for animals, including the camp’s rabbits. Several weeks ago, he developed a fever of 103°F, fatigue, and body aches, followed by the appearance of the skin lesion.
Diagnosis: Tularemia—also called rabbit fever or deer fly fever—is caused by the bacterium Francisella tularensis. It is an insect-borne pathogen of rabbits, squirrels, and other rodents, most commonly found in the western United States and Russia. Symptoms vary by mechanism of exposure but include skin ulcers; irritation and inflammation of the eye; sore throat, mouth ulcers, and tonsillitis; lung involvement with cough, chest pain, and difficulty breathing; and swelling of regional lymph nodes. Tularemia can be successfully treated with antibiotics.
