Ontario tracks spread of tick borne illnesses; top doctor links it to climate change
Ontario's Chief Medical Officer of Health, Dr. Kieran Moore, expects an increase in cases of three tick-borne illnesses in the province: anaplasmosis, babesiosis, and Powassan virus. This rise in cases is directly linked to climate change.
A new regulation requires healthcare providers to report these illnesses to local health officers. The incidence of Lyme disease has already been rising over the past 20 years due to ticks surviving winters. Similar to the United States, where these illnesses followed Lyme disease cases, Ontario is likely to see the same pattern. The ticks' ability to survive winters and breed over their two-year lifecycle is responsible for their migration and the spread of these diseases.
Anaplasmosis causes fever, chills, and affects blood cells. Babesiosis resembles malaria and causes anemia, fever, and chills. Powassan virus can be asymptomatic but may lead to long-term health problems in severe cases. There is no specific treatment for Powassan virus, while anaplasmosis and babesiosis can be treated with antibiotics.
Preventive measures include using insect repellent, wearing treated clothing, and performing daily tick checks. Anyone finding an attached tick and developing a fever within a month should consult a doctor.
This is a bit selfish but I’m bummed about this upsurge in ticks because it’s put such a damper on plans to go hiking etc.
Pick up some Icaridin mosquito repellant! It works great and, unlike DEET, doesn't interact with synthetic materials.
You'll be fine. If you're going into the bush just make sure you use some insect repellant and wear long sleeves with pants. Ensure the pants can be tied off at the ends or tuck them into your socks. Spray yourself in DEET. Enjoy the hiking, it's a great season for it.
Would also be nice if they brought back Public Health testing of ticks for disease
