Black-legged deer tick

Kentucky health experts say Lyme disease is likely underdiagnosed in the commonwealth, in part because it is rarely seen in the state. The number of cases is rising nationally, but just five cases were reported in Kentucky in each of the past two years. Kentucky Department for Public Health policy specialist Mike Schardein tells The Courier-Journal that he believes there are several cases that haven't been confirmed because doctors don't test for it. Lyme disease is spread by the black-legged deer tick, rarely seen in Kentucky.
