Tularemia is an illness caused by a bacteria, Francisella tularensis, which can affect both animals and humans. Most cases occur during the summer months when deerflies and ticks are abundant and the early winter months during rabbit hunting season. Humans can become infected by tick and deer fly bites, skin contact with infected animals and water, and inhalation of contaminated dust and aerosols.

Symptoms vary with how the bacteria enters the body, but common symptoms are: ulcers at the bite location; irritation or inflammation of the eye; sore throat, mouth ulcers; cough, chest pain, difficulty breathing. Steps to prevent tularemia include: Use of insect repellant, avoiding mowing over dead animals, wearing gloves when handling sick or dead animals.
