Tick-Borne Diseases on the Rise in Canada

In Canada, ticks are increasingly spreading various diseases to humans and animals. While Lyme disease has historically been the most recognized tick-borne illness, another lesser-known but rapidly rising bacterial infection, anaplasmosis, is causing concern among health experts ²⁴⁵. The prevalence of black-legged ticks (also known as deer ticks), which transmit these diseases, is expanding across many Canadian provinces, particularly in Eastern Canada and Ontario ²⁵⁶.

Anaplasmosis: A Growing Concern

Anaplasmosis is a bacterial infection transmitted by black-legged ticks ⁴. Physicians are being urged to specifically consider anaplasmosis as a possible diagnosis, especially for patients presenting with unexplained fever in regions where black-legged tick populations are growing ³⁵¹⁰. The Canadian Medical Association Journal (CMAJ) has highlighted the need for increased awareness of anaplasmosis, as it is following closely behind Lyme disease as a health threat ⁵⁸¹⁰.

Key points about anaplasmosis:

• Transmission: Spread by black-legged ticks ²⁴. These ticks range in size from a poppyseed to a sesame seed ³.
• Symptoms: Can present with unexplained fever ¹⁰.
• Geographic Spread: On the rise, particularly in parts of Canada where warming temperatures are pushing tick populations northward ⁴.
• Diagnosis: Doctors are encouraged to consider anaplasmosis in their diagnoses, especially in Eastern Canada ⁵¹⁰.

Lyme Disease: Still a Significant Threat

Lyme disease remains a prominent tick-borne illness in Canada. It is also transmitted by black-legged ticks ⁴. Surveillance data for tick-borne diseases, including Lyme disease, is actively collected and monitored across Canada ¹⁹. The expanding tick populations are contributing to an increase in Lyme disease cases, alongside the emergence of other health risks ⁷.

Other Potential Tick-Borne Risks

Beyond anaplasmosis and Lyme disease, experts warn that expanding tick populations are creating a broader range of health risks in Canada. This includes rare conditions such as red meat allergies, which can also be triggered by tick bites ⁷.

Why the Increase?

Experts attribute the surge in tick populations and the diseases they carry to several factors, including:

• Warming Temperatures: Climate change is allowing ticks to survive and spread into new geographic areas further north than previously observed ⁴.
• Expanding Habitats: Ticks are establishing themselves in more regions across Canada, leading to increased human exposure ²⁷.

The troubling trend of surging tick reports is expected to continue, prompting health authorities and medical professionals to enhance surveillance and public awareness efforts ⁶.
