Lyme disease

Lyme disease is a bacterial infection. Lyme disease can be spread to humans by the bite of ticks.

Ticks are bugs that can settle on tall grass and bushes until they attach themselves to a person or animal passing by. While most tick bites do not result in disease, some do.
Not all ticks carry Lyme disease. Even with a bite from an infected tick, there is only a small chance of getting Lyme disease.


  • Lyme disease can cause symptoms such as fever, headache, joint pain, stiff neck, skin rash and fatigue. 
  • These symptoms can develop anytime from 3 days after being bitten until a month later. 
  • However, in most cases, the symptoms will develop in 7 to 10 days after being bitten. 
  • In some cases more serious neurological or cardiac symptoms can occur after being infected. 
  • If you have been bitten by a tick and develop these symptoms it is important to see your doctor for medical advice.

Tips to avoid tick bites:

  • Avoid areas known to be infested with ticks when possible.
  • Wear light-coloured clothing. It makes ticks easier to spot.
  • Wear long pants and a long sleeved shirt.
  • Wear closed shoes and socks being sure to tuck your pants into your socks.
  • Use a tick repellant that has "DEET" (following the manufacturer's directions). Apply it to your skin and outer clothing. Avoid your eyes and mouth, as well as cuts and scrapes.
  • Check your pet for ticks periodically.

How to Remove a Tick:

  • If you do find a tick on your skin remove the tick immediately in order to prevent infection.
  • Transmission of Lyme Disease is unlikely to occur when the tick was attached for less than a day or so.
  • Do not attempt to burn the tick off

Removal procedure:

  • Remove the tick carefully with tweezers.
  • Grasp the tick as close to your skin as possible.
  • Pull it straight out, gently but firmly.
  • After the tick has been removed from the skin clean the area with soap and water.
  • DO NOT put anything on the tick to try to smother it, like vaseline, alcohol or baby oil.
  • DO NOT squeeze it.  Squeezing the tick can accidentally allow Lyme disease causing bacteria to be introduced into the body.
  • It is important to remember where you were when you were bitten by the tick as this will help to assess your risk of Lyme disease.
