Microbiologist hopes Lyme disease hot zones will get new program's attention

A doctor and microbiologist investigating Lyme disease in the Maritimes is applauding the federal government's new Lyme disease research network aimed at improving diagnosis and treatment.

Dr. Todd Hatchette, the head of microbiology at the Queen Elizabeth II Health Sciences Centre in Halifax,said he supports the evidence-based approach of the $4-million initiative.

And Hatchette hopes the work will focus on areas where Lyme disease is most prevalent, including New Brunswick and Nova Scotia.

In NewBrunswick, Grand Bay-Westfield, Saint John, Rothesay, Quispamsis, St Stephen, Saint Andrews,St. George and Grand Manan Island are all listed by Health Canada as "risk areas." These are defined as areas with a known risk of tick bites and Lyme disease or with a possible risk oftick bites and Lyme disease.

• Federal government spends $4M to fight Lyme disease
• Number of ticks continues to rise as fall tick season arrives

In Nova Scotia, identified risk areas include the Halifax Regional Municipality and parts of Lunenburg, Shelburne, Yarmouth, Pictou and Queens counties.

"I can't say what the government is planning to do, but if it were me I would focus on the areas where Lymedisease is most prevalent," said Hatchette.

"That's where you're going tohave the biggest buy-in from everybody involved from the clinicians who ware seeing the problem, from the patients who are getting the infection, and from the policy-makers who are interested in making sure that the best health care is provided."

The infectious disease is caused byBorrelia burgdorferibacteria and is transmitted through the bite of certain types of infected ticks.

The new frameworkannounced Tuesday by Health Minister Jane Philpott has threepillars:surveillance, guidelines and best practices, and public education and awareness.

"They're great," said Hatchette.

"We needto have a better idea of how many people are affected what the burden of illness is and try to characterize their symptoms and treatments," he said. "And when you do that, you may be able to generate specific questions that can be then addressed in a sound, scientific manner by the research network."

Educatingpatients in how to reduce theirrisk, and educatinghealth-care providers in how to recognize and treat Lyme disease are also key, said Hatchette.

He encouraged people to wear light-coloured clothing when outdoors so they can see if any ticks are on them and to wear DEET-containing mosquitorepellant, which also repels ticks. They should also check themselves for ticks oncethey getback inside, he said.

"If you are able to remove the tick as soon as it attaches, or even before it attaches, then your risk of Lyme disease is basically zero."

Anyone who finds a tick in an area whereLymedisease is common should see a health-care provider, said Hatchette.

Other risk areas across Canada include: southern Manitoba and western Ontario, southern Ontario, southeastern Ontario, southern Quebec and southern British Columbia, according to Health Canada.

Lymedisease in humans wasdesignated anationally notifiable disease in 2009, making it apriority for monitoring and control efforts by the federal, provincial and territorial governments.

"I think it's something that people need to be aware of," Hatchette said. "It's something we're going to hear more about, but it's not something that I would panic about at this point."
