Did you know that the erythema migrans (EM) Lyme rash expands over time and can get quite large? It can be warm to the touch but usually not itchy. The rash can have many forms, with the better known bull’s-eye version seen in only a small percentage of cases. As well, not everyone gets, or sees, a rash. https://www.hopkinslyme.org/lyme-disease-awareness/lyme-disease-rash-presentations-may-not-be-what-you-think/
Did you know that the prophylactic treatment for a tick bite is based upon limited research? The treatment MAY prevent a rash and can result in your Lyme test being a false negative. These ways to diagnose Lyme can be eliminated, but you may still have Lyme, or another tick-borne disease.

As Nova Scotians enjoy the outdoors this summer, the awareness of ticks is looming larger as we hike, garden and explore our beautiful natural environments. The rising tick population in Nova Scotia has led to increased risk and cases of tick-borne illnesses.
Dr. Jonathan Ross, associate regional medical officer of health with Public Health, has spent much of this summer helping Nova Scotians better understand tick-borne illnesses, including how to prevent bites, recognize symptoms and know when to seek care.
Dr. Ross has answered some common questions about ticks in Nova Scotia to help us protect ourselves while enjoying our time outside: https://www.nshealth.ca/news-and-notices/tick-talk-dr-jonathan-ross
