'Every season is tick season': Experts warn of winter Lyme disease risk

Laurenne Schiller loves taking her dog Cousteau for walks along Halifax trails as the weather cools.

But even after the first dusting of snow this week, each walk finishes with a head-to-toe check for blacklegged ticks on her and her collie.

"Talking to other dog owners, people have said they will pick 12 or 15 [ticks] off their dog in an hour-long walk on the trails here," she said.

Schiller now keeps her furry companionon tick medication year-round.

Bit while Christmas tree shopping

Experts saythere is a common misconception that you can't get Lyme disease in the winterbecause people believe ticks are no longer active.

"Wehave this false sense that once it's getting cold, that we're safe. But that's no longer the case," saidDonnaLugar, the Nova Scotia representative for the advocacy group the Canadian Lyme Disease Foundation.

"Even after snow, even after a cold snap, if the temperature does go up, [blacklegged ticks]can be active," she said.

Lugar, who has Lyme disease, said she is beingcontacted increasingly by people who've contracted the disease in the middle of winter.

"A few years ago, someonewas bit while they were in a Christmas tree farm lot picking out their Christmas tree. They ended up being quite ill," she said.

Symptoms similar toflu

Lugar said the risk of misdiagnosis is also greater in the winter because it'sflu season.

Since the symptoms of Lyme disease can appearflu-like, people might think they've caught influenza when they've beenbitten by a tick that carries Lyme disease, she said.

According to the province's health department, the number of reported cases of Lyme disease has been increasing since the first case was reported in 2002. In 2015 there were 247 cases, and in 2016 there were 326.

Andrew Hebda, a zoologist at the Nova Scotia Museum, said he'sreceivingabout 150 ticks every week from medical officesacross the province for identification.

That's more ticks this time of yearthan he was sent during what is known as the peak season in June and July.

He said more than half the ticks he'sseeing now have fed or completely fed, which means they werelikely on the person for more than 24 hours.

"People have let their guard down and haven't been doing the tick checks as diligently," he said.

While the general rule is that ticks are active above 4 C, Hebda saidthere can be warmer pockets of ground that will allow ticks to be active even in cooler temperatures.

"They're active all winter," he said. "We've got ticks being brought in every month of the year."
