Two Minnesota state parks were ranked among the 10 nationwide with the most tick-borne illnesses, according to a recent list from WorldAtlas.
"The Northeast, the mid-Atlantic, and the upper Midwest carry the heaviest tick-borne disease burden in the United States, and the wooded parks in those regions put people directly into the habitat where deer, mice, and infected ticks overlap," according to WorldAtlas.
The ranked parks have documented tick activity, are the subject of published research, or have drawn firsthand accounts of infection, according to the website, which ranked the parks by severity of tick-borne disease in the surrounding region.
In Minnesota, Jay Cooke State Park was ranked No. 6 and Itasca State Park was ranked No. 7.
WorldAtlas noted that Jay Cooke's "heavily wooded trails along the river gorge run through prime deer-tick territory," while Itasca's "diverse terrain makes it a high-exposure area for ticks."
"Lyme disease in Minnesota has climbed sharply, from fewer than 300 annual cases two decades ago to well over a thousand in recent years, driven by warmer winters and growing deer and mouse populations," according to WorldAtlas.
The state parks ranked highest for tick-borne illness nationally were Pine Grove Furnace in Pennsylvania at No. 1, Green Lakes in New York at No. 2, and Harriman, also in New York, at No. 3.
"The parks on this list are not places to avoid; they are places to enter prepared," WorldAtlas reported.
Visitors should use insect repellent with 20-30 percent DEET, wear long sleeves and pants, stay on cleared trails, check for ticks during and after a hike, take a shower within two hours of coming inside, and put worn clothing in a hot dryer for 10 minutes, according to WorldAtlas.
