When it's freezing cold and snowy outside, ticks might not spring to mind, but a team at Mount Allison University wants to get people thinking about the time they were bitten by one.
Research is underway at Mount Allison University to try to assess how well preventive Lyme disease measures work after a bite.
Biology professor Vett Lloyd says the traditional way of dealing with tick bites has been to "wait and see" if people show signs of getting ill, and then to start them on antibiotics for 10 to 21 days if symptoms appear.
But the numbers of blacklegged ticks, the main transmitters of the Lyme disease bacteria, are growing, she said.
"So in the past few years, there's been a switch to essentially assuming the worst, assuming that people may have been infected and giving them a preventive dose of antibiotics before they get ill," Lloyd said.
"The missing piece in there is how well that's working."
Lloyd said the treatment after a tick bite is now usually shorter with a preventative dose, and her team wants to figure out if this approach is actually working at stopping long-term effects.
The longer a tick is attached to someone, the greater the risk of transmission of the bacteria that causes Lyme.
According to a map on the New Brunswick government website, the northern parts of the province have a lower risk of Lyme disease, according to historical disease data and tick surveillance data, while the southwestern regions have higher risk.
Lloyd said the people who get ill after a tick bite are usually good at responding, but she said the team also wants to hear from people who were treated and ended up fine as well.
The survey is available on the Lloyd Tick Lab website, and Lloyd hopes the research will be available to the public by midsummer.
"As Canada has embarked on a big experiment for our benefit, there's no point doing an experiment if you don't check what happens," she said.
"It's a short survey … whether it was single dose, longer dose, whether it's hospital, pharmacy, we want to hear how people did with any kind of treatment for Lyme disease."

Q&A: N.S. has the most ticks in Canada — here's how to protect yourself

Social Sharing The Nova Scotia government recently put out a reminder for people to protect themselves against tick-borne diseases, saying tick populations are growing in every part of the province — in both urban and rural areas. Vett Lloyd, a biology professor at Mount Allison University in Sackville, N.B., and the head of the Lloyd Tick Lab, shared tips with CBC Radio's Information Morning Nova Scotia on how to deal with the insect. This interview has been shortened for length and clarity. Does Nova Scotia have more ticks than usual this year? Unfortunately, yes we do. It was a good winter for ticks. It was a mild, long, cool fall [and] a long, cool spring — a perfect season for ticks. Unfortunately, people are finding them and when we go out, we're finding huge numbers of ticks too. Congratulations to all of Nova Scotia. You win not only the regional contest for who has the most ticks, but nationally. New Brunswick is following behind. P.E.I. is getting a steadily increasing number of ticks. The thing is, once a female tick grabs a blood meal in the fall she will then be able to lay about 2,000 to 3,000 eggs. Their populations can increase really quickly. How is this information tracked? They're not being tracked in a national way, so they're tracked by proxy — so how many people submit pictures of ticks to the government tick-tracking site, eTick. We monitor them indirectly by the number of people who send them in to get tested. And obviously we're only encountering a small number of ticks and some people who are just used to them just kill them and get rid of them. Lyme disease is the main concern with ticks, but we've seen other pathogens that are showing up in recent years. How much of a concern is anaplasmosis? Veterinarians have been monitoring anaplasmosis for the past 10 years or so and they've seen it increase in frequency and also — along with the ticks — spreading northward. Anaplasmosis is a scary disease. If you get sick from it, you get very, very sick and you end up in the [emergency room]. If you're lucky, your ER doctor will realize quickly the fact that you've run out of blood cells. It does respond to treatment, as long as you get treatment. Is anaplasmosis potentially fatal? Yes. Can you get multiple kinds of illnesses from ticks? Can you get anaplasmosis and Lyme disease? Unfortunately, ticks are basically crawly bags of pathogens, so they will frequently have more than one pathogen and they can pass it on, which means that you just get extra sick. It's not just Lyme disease and anaplasmosis. We're also worried about babesiosis, which is a type of parasite. Those are the big ones coming up in this region. It's grim, but at the same time, people need to get outside and enjoy the outside. Quivering inside isn't going to help. There's also pediatric Lyme arthritis. Last summer, a memo was sent by the provincial medical officer of health to health-care practitioners to look out for it. What do you know about that? In an older adult, you would expect arthritis. But if you have an eight-year-old or a 10-year-old suddenly developing arthritis — particularly if it's just in one knee, but not both knees — that memo served to alert physicians that they should think about Lyme disease in that case. So with more Lyme disease, it's showing up in kids. Kids are small, they run around outside and they emit a lot of carbon dioxide, so they're super attractive to ticks. If there's more ticks, are we more likely to see tick-borne illnesses? Unfortunately, yes. But we can modify that to some extent by people just becoming more alert about prevention and doing tick checks. We know they're attracted to moist, warm areas, so people need to check armpits, groins and all of that. How do we properly remove ticks? If you're coming in from outside, do a tick check. That's a really good line of defence. Before you go outside, there are prevention things you can do. There are really good tools for dogs, various tick repellents and things that kill the ticks before the ticks feed long enough to give disease. There are also Lyme vaccines for dogs. For humans, the idea is that we have less hair so we're better at finding ticks [on ourselves]. From the ticks perspective, we don't smell as good [as dogs]. The tick sprays, bug sprays that say they're good for ticks, are generally a good idea. If you're in a high-risk area, you can get clothing that has a repellent in it — commercial or you can make it yourself. When you come in, do a tick check. Strip down. Yes, check moist areas, but if your tick is hungry it could be anywhere. You're looking for freckles with legs. Freckles are not supposed to have legs. If they do, get it off you. There is a lot of mythology about how you remove ticks. Getting it off you is the main point. The bit that will be left embedded in your skin is the mouth part, which is not actually a risk to you. You don't want to squish the tick gut contents back into your bloodstream and you don't want to smear it on cuts.

Tick season is ramping up in Ontario. Here's how you can protect yourself from bites — and Lyme disease

It's looking to be another tick-filled summer in Ontario as factors including climate change grant the Lyme disease-spreading insects footholds in areas they've never been seen before. More than a thousand ticks capable of transmitting the potentially debilitating disease have already been reported in the province as tick season ramps up, with the large majority of sightings centred in the Toronto area. Here's what you need to know about ticks, Gta Explainer Ticks can crawl into your hair or hide in your belly button.

All of Toronto is considered an estimated Ticks and Lyme disease in Ontario As of Wednesday morning, 1,078 Lyme disease-spreading black-legged ticks were reported in Ontario this year, 686 of which were found on people, according to online tick registry The large majority of reports came from southern Ontario, near the Toronto area. ARTICLE CONTINUES BELOW This year's numbers are slightly behind the 1,149 ticks spotted by the same time in 2024, and the 941 in 2023. Across Canada, 1,791 of the bugs have spotted this year, compared to 1,846 counted in the same time period in 2023. Public Health Ontario reported 52 cases of Lyme disease across January and February, according to its latest public health surveillance report. That's an increase from the 48 cases in the same time period in 2024, and the 40 cases in 2023 Jade Savage, the creator of eTick and a professor at Bishop's University, previously told the Star Canada's first tick was spotted in Ontario roughly 50 years ago. Since then, the bugs have been 'slowly expanding its range' — and Lyme disease cases have soared exponentially. Approximately 5,239 people nationwide were diagnosed with Lyme disease in 2024, according to preliminary Health Canada data. That's a more than 36-fold increase from 2009, when only 144 cases of Lyme disease were reported nationwide. Katie Clow, an assistant professor at the Ontario Veterinary College specializing in tick-borne illness, previously told the Star 'most of the evidence supports that it's climate change that is driving' the rise in Lyme disease. ARTICLE CONTINUES BELOW ARTICLE CONTINUES BELOW Much of Canada is too cold for most ticks to reproduce. But with warmer summers and shorter winters, the bugs have been able to spread to new areas, she said. Canada What is alpha-gal?

It's also in Canada. Canada What is alpha-gal?

It's also in Canada. When and where are ticks most active? According to Savage, blacklegged ticks are most active anytime from spring to fall; adults are more common in the spring and fall, and nymphs — an early life stage of the tick — are more common in late spring to early summer. These time periods aren't set in stone — the blacklegged tick can survive year-round 'as long as temperatures are above zero,' Savage said. But if it's too hot, like in the height of summer, they can also dry out easily. Health Canada has highlighted at-risk areas on their interactive map. These areas mostly stick close to the border, and include major cities like Toronto, Ottawa, Winnipeg, Victoria and Halifax.

While it can be effectively treated if caught early on, management becomes much more difficult later in its progression. ARTICLE CONTINUES BELOW ARTICLE CONTINUES BELOW Symptoms of Lyme disease generally appear in two stages, the first often manifesting days after a bite, and the second sometimes taking months to materialize, George Chaconas, a professor specializing in Lyme disease at the University of Calgary Cumming School of Medicine, told the Star. In the first stage, about half of people bitten develop a rash shaped like a bullseye at the site of the bite, Chaconas said. If you find an expanding, target-shaped rash on your body, speak to your doctor immediately. Rashes may also take other shapes or not appear at all. This stage can be treated with a two to three week course of antibiotics: 'Treated Lyme disease typically goes away and the story is over,' said Chaconas. 'But not always.' Once the infection hits the blood, it can travel to different parts of the body, causing different symptoms depending on where it lands and making treatment far more difficult or impossible, he continued. Canada As Canada warms, infectious disease risks spread north Cases of Lyme disease have increased more than 1,000 per cent in a decade as the warming climate pushes the boundaries of a range of pathogens and Canada As Canada warms, infectious disease risks spread north Cases of Lyme disease have increased more than 1,000 per cent in a decade as the warming climate pushes the boundaries of a range of pathogens and Symptoms can range from rashes and headaches to severe joint pain and memory loss, according to Health Canada. In rare cases, it can cause fatal heart infections. Similar to long COVID, some people with Lyme disease develop posttreatment Lyme disease syndrome, or PTLDS, and end up with symptoms that persist for 'weeks, months and years,' Chaconas said. ARTICLE CONTINUES BELOW ARTICLE CONTINUES BELOW A recent study found over 27 per cent of people tested with Lyme disease developed long-term symptoms. How can we protect ourselves from tick bites? The most important thing to do is familiarize yourself with what a tick looks like and perform routine tick checks after hiking or other activities, Sperling previously told the Star. She recommends checking for ticks while bathing, when you're already undressed: 'If you're in the shower and you feel a little lump in your hair, go get somebody to actually look for you,' she said. 'Don't assume that you can ignore it.' If you spot an attached tick, grab some clean, fine tipped tweezers and pinch the bug as close to the skin as possible. Using slow, even pressure, pull the tick directly up out of your skin, trying to keep the mouth parts intact. Then thoroughly clean the area with soap and water or rubbing alcohol. The longer the tick is attached, the more likely it is to transmit diseases, including Lyme disease, so it's crucial to remove ticks as soon as possible, Sperling said. She strongly recommends saving the tick in the freezer, in a bag labelled with the date and location of the bite. That way if you develop symptoms later, you can take the tick directly to the doctor to have it tested. ARTICLE CONTINUES BELOW ARTICLE CONTINUES BELOW When walking in nature, Sperling recommends tucking your pants into your socks or at least wearing long clothing if possible. Light-coloured clothing is best, because then you could better spot ticks if they're on you. As ticks prefer the cool of tall grasses and foliage, try to keep your lawn short in summer and take extra care when walking through brushes and thick foliage, she said. 'Ticks have been around since before the dinosaurs so they're well adapted to survive,' Sperling said. 'We need to learn to live with them.'
