Wood ticks have been unusually active in southern Wisconsin this spring

Already had a run-in with a tick this year?

You’re not alone.

Emergency room visits for tick bites hit their highest known level in southern Wisconsin and have been up across the state in recent weeks, according to data from the Wisconsin Department of Health Services, which began tracking tick-related ER visits in 2022.

Most of the country has seen a similar trend, but it’s been especially pronounced in the Midwest, data from the U.S. Centers for Disease Control and Prevention shows.
