Ticks are a growing problem, no matter where you live
In the grand scheme of things, Lyme disease is a fairly new scientific discovery. It was first traced back to ticks in the late 70s and early 80s. The tick-borne illness can cause a rash, fever, pain, neurological complications, and even facial paralysis. It’s spread by only two of the nearly 50 species of ticks in the United States. Historically, most Lyme cases were limited to a small region, including the Great Lakes area and northeastern US. But thanks to changing temperatures, animal migration and shifts in land use, scientists say tick territory is expanding. So what does that mean for Lyme disease risk? And do you have to be worried about it in your own backyard?
