Tularemia cases rise in the U.S. as disease spreads from animals to humans

Tularemia, also known as "rabbit fever," is a rare infectious disease in the U.S. that can spread to humans from animals, primarily through tick and deer fly bites. Between 2011 and 2022, 2,462 cases were reported across 47 states. The disease is caused by the Francisella tularensis bacteria, which is highly infectious. It can enter the body through bites, contaminated water, or contact with infected animals. Symptoms include fever, ulcers, and respiratory issues, depending on the infection route. Treatment involves broad-spectrum antibiotics, which can significantly reduce the death rate. There is currently no approved vaccine for tularemia in the U.S. Preventive measures include using insect repellent and wearing gloves when handling animals.
