Sites of active field surveillance for ticks in the contiguous region of Maine, New Brunswick and Quebec. The status of known Lyme disease risk areas in 2017 in the neighbouring regions of Quebec (data from 2007 to 2017), New Brunswick (data from 2008 to 2017) and Maine (data from 1989 to 2017) is identified using similar drag sampling methodologies in active field surveillance for ticks. Red points indicate locations where I. scapularis populations have been found and black points indicate where surveillance has occurred but the ticks were not found. Data on surveillance in Quebec are presented with the permission of Institut national de santé publique du Québec and Ministère de la Santé et des Services sociaux, and New Brunswick data are presented with the permission of New Brunswick Department of Health. The red lines indicate the adjacent counties of Kings and St. John (to the south) in New Brunswick from where the majority of human LD cases are reported, and where canine seroprevalence was particularly high in 2015
