Diseases transmitted by ticks

Tick-borne diseases are defined as infections caused by pathogens transmitted during a tick bite.

Lyme disease is the most common in Quebec and is caused by the bacterium Borrelia burgdorferi, transmitted by an infected Ixodes scapularis tick.

Anaplasmosis  (Anaplasma phagocytophilum), babesiosis (Babesia microti), relapsing fever (Borrelia miyamotoi) and Powassan encephalitis (Powassan virus) are other examples of tick-borne diseases in North America.
