In Manitoba, there are several species of ticks but only one species, Ixodes scapularis, is responsible for spreading tick-borne diseases to humans. This tick is more commonly known as the deer tick or the blacklegged tick. Other tick species, such as the more common wood tick, are not effective vectors of disease causing agents in Manitoba.  

There are three reportable tick-borne diseases found in Manitoba: Anaplasmosis, Babesiosis and Lyme Disease. Anyone who feels that they may have contracted a tick-borne disease should see a doctor. Tick-borne diseases can be successfully treated and treatment is most successful in the early stages of infection.
