NEW GLASGOW – When it comes to Lyme disease in Nova Scotia, knowledge is power.

It’s that idea guiding a group of researchers from St. FX, who are looking into the health impacts of climate change in relation to Lyme disease in the province.

Three professors from the university along with a research assistant met at Pictou Centre MLA Pat Dunn’s office in New Glasgow on Tuesday. The research assistant, Jennifer Dunn, fourth year bachelor of science in nursing student, is a cousin of the riding’s provincial representative.

“She approached me and we basically thought why don’t we all get together,” said MLA Dunn.

The meeting gave the researchers a chance to chat with Dunn about his party’s bill to develop a comprehensive Lyme Disease Strategy for Nova Scotia. Pictou East MLA Tim Houston introduced the bill on April 10.

“Currently the province is focused on treatment of Lyme disease,” said Dr. Hugo Beltrami, an environmental science professor. “We’re backing up and finding the data to predict and provide evidence for authorities to prevent the spread of the disease.”

The research, which began last spring, is funded through a series of grants from the Natural Sciences and Engineering Research Council of Canada. While the research isn’t involved in active surveillance out in the field so far, the team has focused on prediction.

“We’re just at the beginning stages of gathering research and meeting with officials in public health,” said nursing associate professor Donna MacDougall.

Currently, the province has certain regulations with regard to Lyme disease, such as a requirement for health-care professionals to report cases of the disease to public health under the Health Protection Act. But according to Beltrami, with models demonstrating that climate change may result in more ticks and potential Lyme disease cases, it may be time for more public awareness.

“What we’ve found with predicted temperature changes in Nova Scotia over the next 100 years, about five degrees Celsius, is that ticks will propagate,” he said. “This gives you an idea about the breadth and ambitions of our research.” 

From 2002 to 2012, there were a total of 171 cases of Lyme disease reported in Nova Scotia. In 2013, there were 154 cases reported. Associate professor Patti Hansen-Ketchum said there might not be enough knowledge of the disease both in government and out in the public.

“A lot of people are still unaware of the risks and there aren’t many public awareness campaigns,” she said. “This may lead to different treatments or even misdiagnosis.”

As for the Lyme Disease Strategy bill introduced by Houston in April, it made it to second reading in the provincial legislature but isn’t law yet. Dunn is unsure if the bill will need to be reintroduced when the house reconvenes in the fall or if it remains on the order table.

FACT BOX:

 

What is Lyme Disease?

Lyme disease is a bacterial infection transmitted by a certain species of ticks known as the blacklegged tick, sometimes called the deer tick. Ticks, seen mostly in summer months, are small insects that will stick to the skin and feed on the blood of animals, including humans. The tick is brown or black and may be as small as the period at the end of this sentence. Before feeding they can be three to five millimetres in length. Mice, squirrels, birds and other small animals can carry the Lyme disease bacteria. It can be passed to humans when ticks feed on infected animals such as birds and become infected and then bite people.

 

How can you prevent Lyme disease?

– Avoid tick-infested areas when possible. Walk on well-travelled paths. Avoid areas with high grass

– Wear light-coloured, long pants and a long sleeved shirt in tick-infested areas and tuck pants into socks.

– Cover arms, legs and other exposed areas of the body.

– Wear shoes that cover your entire foot.

– Check frequently for ticks on the skin, especially on children.

– Use insect repellent containing DEET or Icaridin when in tick-infested areas.

– Remove ticks from skin as soon as possible.

– See a health care provider if symptoms of Lyme disease are noted.

– Use landscaping techniques to reduce the number of ticks around
