Learn About Lyme
There has been an increase in the number of tick bites reported in Ontario this summer. The reason for the increase is not truly understood. During the pandemic, people are walking outdoors through the trails more. Our encroachment on nature has allowed flora and fauna to regenerate.
Lyme disease is caused by the bacerium Borellia that is spread by deer ticks. Deer ticks are endemic in southwestern Ontario. The bite causes a very typical rash called erythema migricans that is not itchy or painful. It usually happens a week after the initial bite and is typically in the shape of a bull’s eye or target. About 80 percent of people who get a bite will get this typical rash. Other symptoms might include headache, fever, fatigue and joint pain. Lyme disease may also cause chronic symptoms that are episodic and include bouts of joint pain, memory changes and fatigue.
Early recognition of the tick bite and treatment can help to reduce long term outcomes of Lyme disease.
- Know the deer tick. The deer tick is an unattractive black legged creature. It adheres to the skin.
- Remove the tick from your skin if you find a bite. You may not always feel a bite so have someone inspect your back or other areas not visible to you after hiking or camping. Keep the tick. You may be able to submit it to your health care provider to have it identified.
- Watch for symptoms.
- Report the bite to your health care provider. If the tick was attached for 24 hours or more, there may be a role for antibiotics or for watchful waiting.
- Observe for symptoms for up to 30 days following a bite.
Enjoy the trails. Use bug spray and sunscreen. Do not avoid the great outdoors but do it safely!
