Indiana health officials are encouraging Hoosiers to protect themselves from tick bites while outdoors as warmer temperatures bring an increase in tick activity across the state. Recent field sampling by the Indiana State Department of Health (ISDH) has found adult and immature ticks (nymphs) carrying the bacterium that causes Lyme disease in a number of counties, particularly in the northern, west central, and south central parts of the state. Anyone who becomes ill after finding an attached tick should see a medical provider immediately and alert the provider to the exposure. Tick-borne diseases can be treated with antibiotics, and prompt diagnosis can help prevent complications. Maps displaying the tick infection data are available at https://www.in.gov/isdh/28130.htm
