May is National Lyme Disease Awareness Month, a time to focus on protecting your health and staying informed about tick-borne illnesses. The Benzie-Leelanau District Health Department reminds residents that Lyme disease, caused by the bacterium Borrelia burgdorferi, is the most common tick-borne illness in Michigan. Ticks are most active in spring and summer, and wooded, grassy, or brushy areas increase your risk of exposure. Early detection and prevention are key to avoiding Lyme disease and other tick-borne infections.
