Vermont confronts rising Lyme disease with expanded tick surveillance
Vermont is seeing a rising Lyme disease risk as ticks expand northward and stay active longer, influenced by climate change and increased outdoor recreation. State surveillance has collected about 25,000 ticks over a decade, with 51% of tested deer ticks positive for Lyme from 2020–2024; in 2025 Vermont reported 2,246 Lyme cases, the second-highest rate in the U.S. Prevention tips include permethrin-treated clothing, checking and showering after outdoor time, and consulting a clinician about antibiotics after a bite. Vermonters can mail ticks for free identification, and Alpha-gal syndrome is rare in the state.
