Its the hard cover tick hikers encounter. Adult ticks range in size from about 0.4 cm to 1.4 cm long. They are oval shaped and appear to have reddish leathery bodies with eight legs. Of course, spiders also have eight legs so you shouldnt be surprised to learn that ticks are also of the arachnid class.

Human Cases Of Lyme Disease In Canada

Between 2009 and 2021, provincial public health units have reported 14,616 human cases of Lyme disease across Canada.

Number of human reported Lyme disease cases from 2009 to 2021

Preliminary 2021 2,851

Reported Lyme disease cases are from those who got the disease while in Canada or while abroad . The 2016 to 2021 Lyme disease cases are reported based on 2016 the Lyme disease case definition. There’s under-reporting because some cases are undetected or unreported.

All 10 provinces voluntarily provided data over the 13-year period. Territories haven’t reported any cases to the Public Health Agency of Canada since Lyme disease became nationally notifiable in 2009. This is because they haven’t had any Lyme disease cases.

Nationally notifiable diseases are infectious diseases identified by the federal, provincial and territorial governments as priorities for monitoring. Provinces and territories report annual notifiable disease data to the federal government. This helps the Public Health Agency of Canada monitor trends within provinces and across the country.

Where Are Ticks Found In Canada

The southern regions of British Columbia, Manitoba, New Brunswick, Ontario, and Quebec are where infected ticks are most frequently detected in Canada, according to the Public Health Agency of Canada. The potentially harmful parasites have developed colonies in several areas of Nova Scotia as well. Ticks are rapidly spreading actress Canada resulting in increased cases of Lyme disease.

Lyme Disease Signs And Symptoms

Most symptoms of Lyme disease in humans usually appear between three and 30 days after a bite from an infected blacklegged tick.

You should contact your local public health unit or speak to a health care professional right away if you have been somewhere that ticks might live and experience any of the following symptoms:

  • rash
  • a bulls-eye rash (a red patch on the skin that is usually round or oval and more than 5 cm that spreads outwards and is getting bigger
  • a bruise-like rash
  • another type of unusual rash
  • muscle aches and joint pains
  • fatigue
  • swollen lymph nodes
  • spasms, numbness or tingling
  • facial paralysis

If not treated, Lyme disease can make you feel tired and weak and, if it gets really bad, it can even harm your heart, nerves, liver and joints. Symptoms from untreated Lyme disease can last years and include recurring arthritis and neurological problems, numbness, paralysis and, in very rare cases, death.

Where Blacklegged Ticks Live

We continue to track where infected and uninfected blacklegged ticks are being found.

Public Health Ontarios Lyme disease page has a map that shows areas in Ontario where they estimate you are more likely to find blacklegged ticks.

Blacklegged ticks are spreading to new areas of the province because of climate change. They can also spread by traveling on birds and deer. While the probability is low, it is possible to find an infected tick almost anywhere in Ontario.

Ticks are most active in spring and summer, but can be found at any time of the year when the temperature is above freezing.

Do Dog Ticks Carry Lyme

Experts warn of rare diseases ticks can carry

The brown dog tick, also called the kennel tick, is common across the U.S. Its unique among ticks because it does well indoors. The adult tick is reddish-brown and usually attaches around the ears or between a dogs toes. This tick rarely bites people, but it can carry serious diseases that affect dogs, such as ehrlichiosis.

Who Is At Risk In Ohio

Anyone who spends time outdoors can be at risk for Lyme disease. The tick that transmits Lyme disease in Ohio, the blacklegged tick, is most often found in wooded, brushy areas. People who frequent these settings may be at increased risk of contracting Lyme disease.

However, it does not take a hike in the forest to encounter blacklegged ticks. The property around many homes can also provide suitable habitat for ticks, particularly those in yards that are next to woods or brushy areas or those with tall grass or leaf litter. That is why it is important to take the necessary steps to prevent tick bites.

Ohioans of all ages get sick with Lyme disease, but data collected by the Zoonotic Disease Program suggest that males are more at risk for Lyme disease than females. Boys between the ages of ten and 14 years appear to be at particularly high risk. Many cases of Lyme disease are reported in females between the ages of five and nine.

Mapping Lyme: Cdc Reveals Distribution Of Lyme Disease

A new study by CDC researchers maps the distribution of Lyme disease spirochetes, Borrelia burgdorferi sensu stricto and Borrelia mayonii, in host-seeking blacklegged ticks or western blacklegged ticks , relative to the previously reported distribution of these vector species. Ticks were considered present in a county if at least one tick was recorded. Counties where ticks have been reported without records of infection may be reported as such either if ticks were not tested or if the pathogen was not detected in tested samples.

Scientists think ticks could be up to 300 million years old. The fossil record even includes amber-encased ticks still engorged with their last dino meal.

Which is amazing. Those blood-sucking arthropods have been doing their thing for longer than humans have existedand their thing includes carrying disease. Ticks are responsible for more than 75 percent of the vector-borne illnesses reported to the U.S. Centers for Disease Control and Prevention every year. The most common of these is Lyme disease with 30,000 to 40,000 annual reported casesthough the CDC estimates the actual number of cases, most of which go unreported, could be more than 400,000 annually.

What Are The Symptoms Of Tick Bites

Steve Dale notes an increase of Lyme in dogs in Pittsburg

The Mayo Clinic notes that the majority of tick bites are painless. The symptoms include redness, swelling and a sore on the skin.

If youre bitten by a tick, youll need to carefully remove it as soon as you can, grasping it by the head with tweezers and gently pulling in a slow and steady upward motion. Take care not to squeeze or twist the tick, and dont handle it with bare hands.

If you can, seal the tick in a container and place it in the freezer. If you develop symptoms, this will help the doctor identify the tick that bit you. After youve removed the tick, wash your hands and the area where you were bitten with warm water, soap, rubbing alcohol or an iodine scrub.

Do keep in mind that there are several tick-borne diseases, so the Mayo Clinic does state you should call your doctor if:

  • You arent able to completely remove the tick
  • The rash gets bigger
  • You think the bite site is infected
  • You think you were bitten by a deer tick
  • And if you experience a severe headache, difficulty breathing, paralysis or heart palpitations, the Mayo Clinic recommends calling 911 or your local emergency number.

    Almost Half Of Deer Ticks Carry Lyme Disease: New Study

    The blacklegged ticks, Ixodes pacificus , and I. scapularis, are known vectors for the zoonotic spirochetal bacteria, Borrelia burgdorferi, which is the pathogen responsible for causing Lyme disease. The ticks, inoculated with the bacterium when they bite infected mice, squirrels and other small animals, subsequently pass the pathogens to their human victims when they obtain a blood meal. Here, you are looking at a dorsal view of a female I. pacificus hard tick.

    Nearly half of more than 2,000 deer ticks collected last year for a new study in Connecticut were infected with Lyme disease.

    Of 2,068 deer ticks tested at the Center for Vector Biology and Zoonotic Diseases at the Connecticut Agricultural Experiment Station in New Haven, Connecticut, 46 percent carry the Lyme disease pathogen Borrelia burgdorferi.

    About 13 percent also carried the human disease-causing pathogen Babesia microti, which causes babesia, a life-threatening infection of the red blood cells in humans.

    The ticks were gathered in the first year of a new federally funded Connecticut-wide surveillance program for ticks and associated tick-borne diseases.

    More than 2,500 ticks were collected throughout spring, summer and fall 2019 from 40 publicly accessible locations in all eight Connecticut counties and screened for five different human disease-causing pathogens.

    What Is A Deer Tick

    Deer ticks also called black-legged ticks are tiny arachnids that measure about one-eighth of an inch once they reach adulthood. Larvae, on the other hand are about the size of a pinhead. Their bodies are dark brown to black and they have dark legs, and, regardless of maturity, all deer ticks need a blood meal to grow.

    The deer tick is primarily found in the eastern United States, particularly the Northeast. Their preferred habitats include wooded areas and fields. Over the years, this arachnid has gained a pretty bad reputation as it is well known for being a carrier of the bacteria that can cause Lyme disease in humans and their pets.

    Number of Lyme disease cases increasing in Michigan

    Researchers have found spirochetes in mosquitoes and other blood-sucking insects. But it has not been proven that they can transmit the infection.

    A tick is uniquely suited to carry and spread Lyme disease. Spirochetes have co-evolved with ticks over millions of years. Tick saliva contains immune suppressors that help disseminate the bacteria throughout the hosts body. And, because ticks feed on many different animals, they can spread the disease widely.

    Lyme Disease Risk Areas

    Blacklegged ticks are spreading to new areas in Canada in part due to climate change. They can also spread by travelling on birds and deer. You can sometimes find blacklegged ticks in areas outside of where they’re known to live.

    You’re most likely to encounter ticks during the spring, summer and fall. However, ticks can be active at any time of the year when the temperature is consistently above freezing. The best way to prevent Lyme disease is to protect yourself against tick bites. Always take precautions against tick bites when you’re in wooded or grassy areas.

    Using data from active and passive tick monitoring, the Public Health Agency of Canada identifies areas where:

    • tick populations may be emerging
    • people are most at risk of getting Lyme disease

    How Is Lyme Disease Diagnosed

    Lyme disease is difficult to diagnose because symptoms are not consistent and may mimic other conditions. The primary symptom is a rash, but it may not be present in up to 20% of cases.

    Diagnosis for Lyme disease must be made by a healthcare provider experienced in recognizing Lyme disease. Diagnosis is usually based on symptoms and a history of a tick bite. Testing is generally done to confirm the diagnosis and rule out other conditions. This may need blood and other lab tests.

    Research is underway to develop and improve methods for diagnosing Lyme disease.

    The symptoms of Lyme disease may look like other medical conditions or problems. Always talk with your healthcare provider for a diagnosis.

    What Should I Do If I Get Bitten By A Deer Tick

    Pull back gently but firmly, applying even and constant pressure. Do not shake or twist. Do not squeeze, crush, or puncture the ticks body, as its bodily fluids may contain infectious organisms. After removing the tick, wash the skin and hands thoroughly with soap and water.

    How are deer ticks linked to Lyme disease?

    Deer ticks only act as disease vectors. They carry the disease and transmit it, but they do not cause it. Sometimes deer ticks carry the bacteria from an infected animal onto the human body. The bacteria enter the body when the tick begins to suck blood, which may take some time.

    Should I Be Tested For Lyme Disease After A Tick Bite

    Lyme testing relies on detecting antibodies the bodys reaction to the germ not the germ itself. It takes time for the body to make antibodies, at least a couple of weeks after you have become infected. Someone with symptoms of very early Lyme disease is likely to have a negative Lyme antibody test. On the other hand, false positive Lyme tests can happen, so someone without symptoms of Lyme disease who tests positive is unlikely to really have the disease. Testing for Lyme disease shortly after a tick bite is not helpful, says Dr. Baer and may lead to a prescription for a medication that you just dont need.
