"Canadians need to get ready for a slow and steady invasion from south of the border, according to scientists. The threat comes from different varieties of ticks carrying dangerous pathogens that are looking to establish themselves in Canada. According to the Government of Canada, there are already more than 40 different types of ticks in Canada."
"The most well known is the blacklegged tick, or deer tick, which carries the bacteria that causes Lyme disease. It has common symptoms of fever, fatigue and a "bull's-eye" rash. If untreated, it can cause severe joint, heart and nervous system complications."
"I would say that people are very alarmed and very scared about the presence of the transmission of tick-borne diseases. We don't have a vaccine for Lyme yet, although we know very well that ticks carry multiple pathogens. So a vaccine for Lyme won't be the best solution for protecting us from this."
"Scientists say other species of ticks carrying troubling pathogens are travelling our way from the northern United States at a rate of about 50 kilometres per year. Some have already been spotted, but they have not yet established themselves in Nova Scotia. Of concern is the lone star tick. It can carry a pathogen that can leave a bitten person with a severe allergy to meat."
More than 40 types of ticks are already present in Canada, and additional species are expected to migrate north. The blacklegged, or deer, tick can transmit the bacteria that causes Lyme disease, which may begin with fever, fatigue, and a bull’s-eye rash and can lead to severe joint, heart, and nervous system complications if untreated. Scientists report that some tick species carrying troubling pathogens are moving from the northern United States into Canada at about 50 kilometers per year. The lone star tick is a concern because it can transmit a pathogen linked to severe meat allergy after a bite. A new Canadian Tick Research and Innovation Centre at Acadia University aims to understand, prevent, and manage ticks and tick-borne diseases, and there is no Lyme vaccine yet.
