Health officials are advising residents to take precautions as West Virginia has been designated as a high-incidence Lyme disease state since 2017. The bacterial infection is caused by tick bites and can spread to the heart and nervous system if left untreated. The West Virginia Department of Health has urged those who spend time outdoors to remain vigilant and monitor common symptoms, which include skin rash, fatigue, headaches, fever, and joint swelling. Ticks must be attached for 24 hours to transmit Lyme disease.
