The chew from this tick can have an surprising side-effect: An allergy to a substance referred to as alpha-galactose, a sugar molecule found each in the cells of most mammals and in the saliva of the lone star ticks that chew them.

The variety of confirmed alpha-gal syndrome (AGS) circumstances in Canadians is small, with stories of two Canadians with this allergy by the CBC and the Toronto Star.

Bouffard says specialists imagine the circumstances affecting Canadians are the results of bites that occurred throughout journey to areas in the United States the place the lone star tick is extra established.

According to microbiology journals, AGS comes from alpha-gal molecules in a tick’s saliva, which enters the blood stream of its host. This causes an immune response to the substance.

Tracking Changes

Data from etick.ca reveals the variety of lone star ticks reported in Canada is roughly 10 every year.

At the time of writing, etick lists seven lone star ticks reported in the nation this 12 months, with most in Ontario, and one in Nova Scotia.

Bouffard says numbers could improve, as migration patterns of ticks are altering on account of hotter temperatures, deforestation and the constructing of highways. These all make the journey to Canada simpler for animals carrying ticks, and makes the local weather extra hospitable for ticks to turn into established.

Tracking is essential as a result of “it’s the first step in knowing which ticks that can pose a risk to humans are in what areas,” mentioned Bouffard.

Platforms like etick assist researchers monitor tick migration and distribution by permitting anybody to add a photograph of a tick they discover to the web site. The tick will then be recognized inside one to 2 enterprise days.

This provides the submitter details about any dangers that tick carries, whereas offering researchers knowledge to additional doc tick distributions, scorching spots and threat areas in Canada.

“It’s a win-win for both us and the users,” mentioned Bouffard.

People who’ve been bitten by ticks also can hold the insect and take it to the physician’s workplace to have it examined for any diseases.

Prevention and Protection

Ticks can carry a spread of pathogens, past Lyme illness and AGS, says Ogden. The finest technique to keep away from any tick-borne diseases is thru prevention and early detection.

To cut back the possibilities of being bitten by a tick, Bouffard and Ogden each advocate utilizing bug spray with DEET, carrying light-coloured garments that make ticks simpler to identify, and tucking lengthy pants into socks to cease ticks climbing up the leg.

Bouffard says common tick-checks are an essential behavior to undertake. Especially after spending time outdoors in wooded or grassy areas.

“Take a shower,” says Bouffard. “It may dislodge any tick that is attached to you already and will allow you to perform a thorough tick-check.”
