Lyme Disease

What is Lyme disease?

Lyme disease is caused by a bacteria transmitted by the bite of an infected tick.

Tick bites are generally painless and often go unnoticed.

IF you get bit by a tick, you must remove it immediately. To know how to do this, consult the page on how to remove a tick. Take note of the date and your location when you got bit. Also note the place on your body where you were bit. This information will be useful if you have to consult a doctor.



The first symptoms of Lyme disease generally appear within 3 to 30 days after being bit by the infected tick.

Other symptoms that can accompany the skin rash:

  • stiff neck;
  • muscle pain.
