Kansas Tick Illnesses Surge Past 2020 Lows

Tick-borne illnesses in Kansas have seen an increase since 2020, with ehrlichiosis now the most prevalent disease contracted in the state. Although overall illness numbers have risen recently, they are approximately half of the totals recorded before 2020. For example, 311 cases were reported in 2019, compared to 80 in 2020, with subsequent yearly totals ranging between 111 and 156.

Ehrlichiosis is spread primarily by the lone star and blacklegged ticks, two of the four common tick species found in Kansas. Other tick-borne diseases tracked by the state include anaplasmosis, Lyme disease, Rocky Mountain spotted fever, and tularemia. Health officials stress that while most tick bites do not lead to illness, preventative measures are key. These include using EPA-registered insect repellents, wearing long sleeves and pants, tucking pants into socks, and performing thorough tick checks after spending time outdoors.

Prompt removal of attached ticks and seeking medical attention if a rash or fever develops within days or weeks of a bite are also recommended. The Kansas Department of Health and Environment advises using repellents containing DEET, picaridin, IR3535, or oil of lemon eucalyptus. Proper tick disposal, such as flushing them down the toilet or placing them in alcohol, is also advised.
