  • I-TICK Tick Dragging (Active Surveillance)
    • As part of our active surveillance, I-TICK conducts bi-weekly tick dragging in two counties and once a month “blitzes” in southern Illinois. Specific county health departments may also conduct their own active tick dragging surveillance and submit their findings to I-TICK.

Table 3: Summary of species and life stage for 2019 I-TICK Active Surveillance (as of June 19, 2019)

I-TICK Researchers are carrying out tick dragging in Douglas and Moultrie counties. The status of I. scapularis is unknown in these counties. Through our active surveillance we hope to determined what ticks are established or present in these two counties. Our southern Illinois “blitzes” take place in Hamilton, Jackson, Jefferson, Perry, Pope, and Williamson counties once a month. St. Clair County Health Department conducted their own tick dragging and submitted ticks found to I-TICK.
