Lyme Disease, Anaplasmosis, and Babesiosis, Atlantic Canada

This research letter penned by federal and provincial public health professionals highlights the small but real risk of Maritime residents contracting the tick-borne parasite Babesia microti from the same ticks that carry Lyme disease and anaplasmosis in the region, setting up a scenario where locals could potentially be infected with multiple tick-borne infections from a single bite. The authors note that while babesiosis has been previously confirmed in humans, ticks, animals and blood donations in western and central Canada, the case describe in this letter marks the first time a patient in the Maritimes has come down with a laboratory confirmed case.
