Toronto identifies areas where ticks that cause Lyme disease are found

Toronto public health officials havebegun to put up signs in the city where blacklegged ticks have been found and theyare warning the public that these ticks can spread Lyme disease.

"The risk of acquiring Lyme disease in Toronto is considered low," says Dr. Howard Shapiro, Associate Medical Officer of Health andDirector ofHealthy EnvironmentsatToronto Public Health, said Tuesday.

"However, this is the time of year where individuals and families start to enjoy time outdoors, so it is important that people know where ticks have been found and how to prevent Lyme disease."

The areas identified in the city as having blacklegged ticks are Morningside Park, Cedar Ridge Park andRouge Park in Scarborough as well asAlgonquin Island,part of the Toronto Island group of parks, across the harbour from the city's downtown.

"Blacklegged ticks are what we are concerned about," he said.

The ticks can range in size from a poppy seed to pea, depending on whether they have fed recently.

Shapiro said ticks are found in wooded or bushy areas, where there are lots of leaves on the ground or tall grasses. He said they are not usually found on mowed lawns, sports fields or paved roads.

Dr. Howard Shapiro tells CBC how people can protect themselves during tick season.

To avoid being bitten by a tick, he encouragedmembers of the public to:

• Stay in centre of trails to prevent contact with ticks.
• Wear light-coloured clothing so ticks would be visible.
• Checkyour full body and head for ticks.
• Use insect repellent.
• Take a shower after walks in the woods.
• If you find a tick, remove it as soon as possible because early detection and removal helps to prevent Lyme disease.

And he urged the public to check their children and pets for ticks.

Public health officials demonstrated to reporters on Tuesdayhow ticks are collected in the natural environment under the city's blacklegged tick surveillance program.

Although the risk of becoming infected is low, Shapirosaidprotection against black-legged tick bites can further reduce the risk of infection.

Symptoms can start about three days to one month after a tick bite, often with a circular rash that looks like a bulls-eye. Symptoms includefever and chills,headache, stiff neck, muscle and joint pain andfatigue.
