Abstract:

In 2022, a total of 7,030 I. scapularis were submitted through passive surveillance from all provinces, while 911 I. pacificus were submitted from British Columbia (n=909) and Yukon (n=2). Ixodes scapularis submissions peaked in May and again in October. For I. pacificus, submissions peaked in May with a second, smaller peak in November. Six tick-borne pathogens (Anaplasma phagocytophilum, Borrelia burgdorferi, Borrelia miyamotoi, Babesia microti, Babesia odocoilei, Powassan virus) were identified from the I. scapularis collected by dragging in Manitoba, Ontario, Québec, New Brunswick or Nova Scotia.
