Ontario researcher seeks tick-bite patients to assess gaps in Lyme disease testing

A student-researcher in Kingston, Ont., is currently looking to assess how potential tick-bite and Lyme disease patients are assessed and cared for in Ontario.

Emilie Norris-Roozmon, a master’s candidate at Queen’s University, said she’s trying to measure the tick-bite “patient experience.”

The trouble with tick-borne illness is that there’s many people who are frustrated and they’re sick. Yet they don’t have a definitive diagnosis,” Norris-Roozmon said.

Lyme disease is just one of the diseases transmitted from the bite of a black-legged tick, otherwise known as a deer tick, but it can become a serious illness if not treated.

According to Ontario Public Health, “the number of Lyme disease cases reported in Ontario has increased since the mid-2000s when less than 100 cases were reported annually. In 2017, 1,003 confirmed and probable cases were reported,”

In 2018, the province recorded 624 cases of Lyme disease. Data for 2019 is not yet available.

Tick populations have grown across Canada as warmer weather has settled in, according to Ontario Public Health, resulting in higher cases of Lyme disease.

Because the prevalence of the disease in Ontario is fairly new, Norris-Roozmon said there is currently a “gap in knowledge” when it comes to testing that leads to false positives and negatives. She also added that Lyme disease or other illnesses from ticks are treatable with antibiotics if they are caught early, but if testing isn’t accurate, it can lead to dangerous results.

“The issue is that, of course, doctors don’t want to just blanket statement, prescribe people antibiotics if there’s no evidence for Lyme. So this causes frustration because if left untreated Lyme and other tick borne diseases, they manifest into something that’s chronic,” she said.

The province and public health experts say its important for people to be vigilant when it comes to ticks, especially in hotspots, by covering their skin when they go outside, wearing closed-toe shoes and insect repellent and checking themselves and their pets for ticks.

What Norris-Roozmon is hoping to help achieve is a better way of testing and identifying tick-born illness in case of a tick bite.

I think that the the best preventative care is always what’s best, what we strive for is to have early detection and early diagnosis. And unfortunately, if that is not the case, then, of course, your care may be more complicated,” she said.
