the disease was first recognized in 1975 after large numbers of children were being diagnosed with juvenile rheumatoid arthritis in lyme, connecticut and two neighbouring towns.
health canada says that provincial public health units have reported 14,616 human cases of lyme disease across the country between 2009 and 2021. the risk is considered on the rise because blacklegged ticks are spreading to new areas in canada, a shift attributed in part to climate change. the ticks can also spread by travelling on birds and deer.
body rash, fever, muscle aches are common symptoms
while symptoms of lyme disease vary in severity, the typical ones to look for include fever, headache, fatigue and a characteristic skin rash, erythema migrans, that looks like a circular red bull’s eye. detection is key — left untreated, the infection can spread to the heart, joints and nervous system.
a tick has to attach to your skin for at least 24 hours to transmit the infection, advises health canada, but often, people don’t notice a tick bite because bites are usually painless and ticks are so tiny. most cases can be treated with a few weeks of antibiotics, the cdc says.
protect yourself outdoors
ticks are most common in spring, summer and fall, but they can be active at any time when the temperature is consistently above freezing.
protect yourself when you’re working outdoors or spending time hiking, camping, fishing, golfing or even gardening by using insect repellent and wearing long sleeves and pants to cover your skin. also, stay on cleared paths and walkways.
do a tick check after your time outdoors on your body and your gear, and remove any ticks promptly if they attach. showering or bathing is also recommended, along with putting your clothes in a dryer for 10 minutes on high heat.
