Ixodes scapularis ticks submitted through passive surveillance that were infected with Anaplasma phagocytophilum, Babesia microti and co-infections, Canada, 2019^a,b

^a Each symbol represents the probable location of acquisition of an I. scapularis single or multiple tick submission submitted through passive surveillance that tested positive for A. phagocytophilum (n=141), B. microti (n=13) or a co-infection (n=29). Co-infections were limited to only single submissions of I. scapularis, and include B. burgdorferi + A. phagocytophilum (n=26), B. burgdorferi + B. microti (n=2) and A. phagocytophilum + B. microti (n=1)

^b No passive surveillance was conducted in Yukon, Northwest Territories or Nunavut for I. scapularis or I. pacificus ticks. Passive tick surveillance has been discontinued in the entire province of Nova Scotia, and some regions of Ontario and Québec; however, individuals could submit ticks directly to the National Microbiology Laboratory Branch from these jurisdictions
