Blacklegged ticks, long associated with Lyme disease, are now spreading other infections in Canada, including anaplasmosis and babesiosis. With climate change pushing ticks further north and Ontario reporting rising cases, we must expand our testing and awareness.

Lyme remains the most common tick-borne illness, with around 2,500 cases reported annually—up sharply from 144 in 2009. But other serious infections are now appearing. In 2023, Ontario recorded 40 cases of anaplasmosis and 15 of babesiosis. Both diseases became provincially reportable that year.

Symptoms of these infections—fever, fatigue, joint pain—can overlap with Lyme, making co-infection possible. In New England, up to 8% of Lyme cases are co-infected with either anaplasma or babesia. Experts recommend ordering tests for all three when Lyme is suspected, as public health labs can identify them.

Anaplasmosis is a bacterial illness that can be transmitted within 24–48 hours of a tick bite. Symptoms typically appear within 5–21 days and include sudden flu-like symptoms. While many recover on their own, those with weakened immune systems face higher risks. Doxycycline, the standard Lyme treatment, also works for anaplasmosis.

Babesiosis, caused by parasites that infect red blood cells, can range from asymptomatic to severe. It may cause malaria-like symptoms such as fatigue, dark urine, and jaundice. The disease is most dangerous for the immunocompromised, with a 5%–20% fatality rate in hospitalized cases. Treatment involves antimicrobial and antibiotic combinations.

Other tick-borne illnesses, like Rocky Mountain spotted fever and Powassan virus, are rarer but present in Canada.

Preventive steps include wearing long sleeves, using insect repellent, and doing tick checks after outdoor activity. Pets should also be checked. Ticks should be removed carefully with tweezers, using a twisting motion—never crushed.

Despite the risks, outdoor activity remains safe with proper precautions. Awareness and prevention are key to managing the growing threat of tick-borne illnesses in Canada.
