For the first time in Quebec, a person has contracted Rocky Mountain spotted fever, a tick-borne disease that is potentially fatal, a doctor stated on Monday. The patient, recently infected in Estrie, has nevertheless responded well to treatment and has now recovered.

As milder temperatures favour the proliferation of ticks, we expect to see more and more cases in the coming years in Quebec, says Dr. Alex Carignan, infectious disease microbiologist and professor in the Faculty of Medicine and Health Sciences at the University of Sherbrooke. “It is concerning, because it is an infection with significant severity.”

The disease, which is treated with antibiotics, can lead to death if not properly managed. The first symptoms, which appear a few hours or days after a person is bitten, include a high fever, headache, muscle aches, and skin lesions in the form of small red spots.
