CDC reports rise in tularemia cases in the US as detection improves

Cases of tularemia, or "rabbit fever," are increasing in the U.S., with a 56% rise reported from 2011 to 2022 compared to the previous decade. The Centers for Disease Control and Prevention (CDC) highlights improved detection methods as a possible reason for this increase. Tularemia is caused by the bacteria Francisella tularensis, primarily affecting rabbits and rodents. Humans can contract it through bites, contact with infected animals, or contaminated water. Symptoms vary but can include chills, headache, and severe sore throat. The disease has a low death rate, under 2%, but can be higher in severe cases. There is no vaccine, but antibiotics can treat it. Those most at risk include children, older men, and certain Native American populations.
