What is Lyme disease and how do you get it?

  • Lyme disease is caused by a bacteria that is transmitted by ticks, specifically the black-legged tick. These are very small and often difficult to see! They are usually located low to the ground, in tall grass or shrubs

How will I know I have been bitten?

  • Unlike many other bites from insects and parasites, tick bites are usually painless and not itchy. Some people are unaware that they have even been bitten, while others develop a bull’s-eye-like rash at the site.

What should I do if I know/suspect I have been bitten by this tick?

  • If you find the tick still on you, you should remove it! Make sure that you visit a doctor to determine if Lyme disease testing is recommended. Make sure to inform them that you have been active outdoors. Luckily, early treatment is often successful.

What are the symptoms of Lyme disease?

  • In addition to the aforementioned bull’s-eye-like rash, other clinical signs can include fever, chills, extreme fatigue, or flu-like symptoms.

How can I prevent getting Lyme disease?

  • Prevention should be aimed at avoiding tick bites:
      • Use bug repellent (especially those containing DEET)

        • Avoid shrubs, tall grass and other common tick habitats!

          • Wear clothing that covers as much of your skin as possible!

            • Tuck your pants into your socks

              • When finished outdoors, check yourself for the presence of ticks, or their tell-tale bull’s-eye-like rash!
