Overview

• The CDC reports a 56% rise in tularemia cases in the U.S. from 2011-2022 compared to the previous decade, with 2,462 cases documented across 47 states.
• Tularemia, caused by the bacterium *Francisella tularensis*, can be transmitted through tick and deer fly bites, contact with infected animals, inhalation of contaminated aerosols, or consuming untreated water.
• The disease disproportionately affects Native Americans, children aged 5-9, and older men aged 65-84, with central U.S. states like Arkansas, Kansas, Missouri, and Oklahoma reporting the highest numbers.
• Changes in diagnostic criteria, including the use of PCR testing since 2017, have contributed to the increase in reported cases, alongside potential actual rises in infections.
• Prevention measures include using insect repellents, wearing protective clothing, avoiding untreated water, and taking precautions when handling wildlife or mowing lawns in areas with potential exposure.
