Blacklegged Tick Expansion: Ontario Residents Face Rising Lyme Disease Risk
Niagara, Ontario – A surge in blacklegged tick populations across Ontario is raising alarms among public health officials and outdoor enthusiasts alike. new research highlights a significant expansion of these disease-carrying pests, increasing the risk of Lyme disease and other tick-borne illnesses.
Tick Populations on the Rise: What you Need to Know
Brock University researchers are closely monitoring the spread of Ixodes scapularis, commonly known as blacklegged ticks or deer ticks, across the Niagara region. These ticks are known carriers of Borrelia burgdorferi, the bacteria responsible for Lyme disease.The team’s work aims to understand the factors driving the tick expansion and inform the public about potential health risks.
“Tick research is incredibly arduous,” explains Nick Benton, a Biological Sciences PhD student at Brock. “Identifying if these ticks are transmitting certain pathogens is important for modeling exposure risk and understanding how tick ranges and potential disease risks are expanding in an area.”
The growing Range of Blacklegged Ticks
Fiona Hunter, a medical and veterinary entomologist at Brock, notes that blacklegged ticks were found in only four of 30 Ontario sites evaluated back in 2009. Now,they can be found virtually anywhere in Niagara.
“From 2009 to now, you can go out virtually anywhere in Niagara and pick up Ixodes scapularis – that is a major public health concern,” Hunter states.”We have this deadly tick expanding its range; it started in southern Ontario, but it’s expanding its range northward.”
Evidence suggests that climate change and rising temperatures are major drivers of the tick population’s expansion.Warmer weather allows ticks to survive and thrive in new areas. Deer and mouse populations also play a role, as these animals serve as hosts for ticks in their different life stages.
Did You Know? According to the Public health Agency of Canada, cases of Lyme disease have been steadily increasing, reaching over 3,000 reported cases in 2021, highlighting the growing public health concern.
Identifying and Removing Ticks Safely
The good news is that ticks don’t begin feeding instantly. early detection and proper removal can prevent serious illness.
Benton advises, “It’s important to take out a tick as soon as possible, becuase the longer it feeds on you, the more likely it is to transmit pathogens into your bloodstream.” He recommends using forceps or tweezers to gently pull the tick straight out, avoiding damage to the tick.
Pro Tip: When removing a tick,avoid using heat (like a match) or substances like petroleum jelly,as these methods can cause the tick to burrow deeper or regurgitate infected fluids.
Beyond Lyme Disease: Other Tick-Borne Illnesses
While Lyme disease is the most well-known illness spread by tick bites, researchers are also testing for other pathogens, including:
- Anaplasma phagocytophilum (Anaplasmosis)
- Babesia microti (Babesiosis)
- Powassan virus (Powassan Virus disease)
- Rickettsia rickettsii (Rocky Mountain spotted fever)
- borrelia bacteria (Tick-borne relapsing fever)
Although rarer, these diseases can cause serious symptoms if left untreated.
“The diseases caused by these pathogens can cause serious symptoms or even death if left untreated,” Benton warns.
Protecting Yourself and Your Pets
Staying informed and taking precautions are the best ways to protect yourself and your family from tick-borne illnesses. Be vigilant when spending time outdoors, especially in wooded or grassy areas.
Here’s a quick comparison of common ticks and the diseases they may carry:
| tick Species | Common Name | Primary Diseases Transmitted |
|---|---|---|
| Ixodes scapularis | Blacklegged Tick (Deer Tick) | Lyme Disease, Anaplasmosis, Babesiosis, powassan Virus |
| Dermacentor variabilis | American Dog Tick | Rocky Mountain Spotted Fever, Tularemia |
| Ixodes cookei | Groundhog Tick | Powassan Virus (rarely Lyme) |
The research team plans to share their findings with the community, offering valuable insights into the risks present in their environment. Their goal is to empower residents with the knowledge and resources they need to stay safe.
Evergreen Insights on Tick Prevention
Tick season typically runs from spring through fall, with nymphal ticks being most active in late spring and early summer, and adult ticks being more prevalent in the fall. Though, ticks can be active any time the temperature is above freezing.
- Wear Protective Clothing: Long sleeves,pants,and closed-toe shoes can create a barrier against ticks.
- Use Insect Repellent: Apply insect repellent containing DEET or Icaridin to exposed skin and clothing.
- Check Yourself and Your Pets: Conduct thorough tick checks after spending time outdoors, paying close attention to areas like the hairline, ears, armpits, groin, and behind the knees.
- Create a Tick-Safe Zone: Keep lawns mowed, clear brush and leaf litter, and create a barrier of wood chips or gravel between wooded areas and your yard.
- Consider Tick Control Measures: consult with a pest control professional about options for treating your yard to reduce tick populations.
Frequently Asked Questions About Ticks and Lyme Disease
-
Question: What are the early symptoms of Lyme disease?
Answer: Early symptoms of Lyme disease can include a bullseye rash (erythema migrans),fever,fatigue,headache,and muscle aches. -
Question: How is Lyme disease diagnosed?
Answer: Lyme disease is typically diagnosed based on symptoms, physical findings (such as the bullseye rash), and blood tests. -
Question: What is the treatment for Lyme disease?
Answer: Lyme disease is usually treated with antibiotics, such as doxycycline or amoxicillin. Early treatment is crucial for preventing long-term complications. -
Question: Are there any long-term effects of Lyme disease, even after treatment?
Answer: Some individuals may experiance post-treatment Lyme disease syndrome (PTLDS), characterized by persistent fatigue, pain, and cognitive difficulties, even after antibiotic treatment. -
Question: Can pets get Lyme disease?
Answer: Yes, pets, especially dogs, can get Lyme disease from tick bites. Symptoms in pets can include fever, lameness, joint pain, and lethargy. Consult a veterinarian for diagnosis and treatment.
Stay vigilant, stay informed, and protect yourself and your loved ones from the risks of Lyme disease and other tick-borne illnesses.
