What is being done about Lyme disease in Middlesex-London?
The Middlesex-London Health Unit follows up on human Lyme disease cases. The Health Unit looks for blacklegged ticks to find out whether or not Lyme disease is in the area. The Health Unit monitors ticks by having the public submit any ticks that they find to the Health Unit, and by going out to look for ticks in wooded or grassy areas where ticks might be found. When ticks are found, they are identified in the laboratory. If a blacklegged tick is found on a human, it is sent away for testing to see if it carries Lyme disease. Learn more by reading about tick surveillance.
