Canine Borrelia burgdorferi seroprevalence among surveyed households in Watauga County, North Carolina, USA, 2017–2021. Colored hexagons indicate the percentage of households with dogs positive for B. burgdorferi antibodies during 2017 (A) and 2021 (B). A total of 2,739 client households were included in the analysis. Seroprevalence was defined as the percentage of IDEXX SNAP 4DX Plus assay (IDEXX Laboratories, Inc., https://www.idexx.com) results that were positive for B. burgdorferi antibodies in dogs living within surveyed households. Lighter colors indicate areas with no or low canine B. burgdorferi seroprevalence; darker colors indicate areas with higher canine B. burgdorferi seroprevalence. Gray hexagons indicate areas with no household data.
