Lyme disease is transmitted by the blacklegged tick and the disease is spreading across the state.

Now Bay, Genesee, Shiawassee, Gratiot, Huron, Arenac, Ogemaw, Oscoda, and Alcona Counties are considered at potential risk for Lyme disease. That means they are adjacent to a county and/or blacklegged ticks but are not infected with the Lyme disease bacteria.

Blacklegged ticks were first detected in 2002 along the west coast of the state. Since that time they have spread northward along the Lake Michigan coast. The Upper Peninsula has also been hard-hit, experts say that’s due to the proximity to Wisconsin.
