A recent increase in tularemia cases in Minnesota has prompted health officials to raise awareness and issue prevention measures for both humans and pets. The illness, also known as “rabbit fever,” is caused by the bacteria Francisella tularensis, which is commonly found in small rodents, rabbits, squirrels, and beavers.
According to the Minnesota Department of Health, up to six human cases are typically reported each year, but this year’s total has already reached five. The causes of these cases include tick bites, scratches from infected cats, and exposure to animals with tularemia through contact.
Symptoms of tularemia in humans can appear within three to 14 days after exposure and include sudden fever, skin wounds or ulcers, swollen lymph nodes, headaches, and chills. For pets, symptoms are similar but may include high fever, weakness, lack of appetite, and ulcers.
To prevent the spread of tularemia, health officials recommend keeping cats indoors, preventing tick bites through medication and insect repellent, checking yards for rabbit nests or dead animals before mowing, and avoiding contact with sick or dead wild animals. Anyone bitten or scratched by an ill animal should contact their healthcare professional immediately. Pet owners are also advised to consult with a veterinarian if they have concerns about their pets contracting tularemia.
