Diagnosis: Lyme disease is the most common tick-borne illness in the United States, with more than 25,000 confirmed cases in 2014. It is concentrated mostly in the northeast and upper Midwest, although in 2014, only five states (Colorado, Hawaii, Louisiana, New Mexico, and Oklahoma) reported no incidence. Lyme disease is caused by Borrelia burgdorferi, which is transmitted to humans by the Ixodes tick.
