Distribution Map of Our Relative Knowledge of Swimmer’s Itch in Alberta. This map depicts the distributions of where swimmer’s itch cases have occurred (orange circles), and the potential for where swimmer’s itch could occur based on the presence of host species. Vertebrate potential host species are depicted by blue diamonds and invertebrate, gastropod potential host species are depicted by a blue ‘x’. Where the vertebrates and invertebrates overlap is where there is potential for swimmer’s itch transmission. Latitude and Longitude are depicted by tick marks on the outer edge of the map. The graphs on the right-hand side are showing the distribution of overlapping points of latitude and longitude for all three data sets (vertebrate, invertebrate, and swimmer’s itch cases). The x-axis being either points of Latitude or Longitude, and the y-axis describing frequency of overlap, as points are stacked (Min = 1, Max = 111, Sum = 607, Mean = 6.07, SD = 13.3). Most overlapping points, and those with greatest frequency, lie within the red bounded box
