Cold sore: the causes

The cause of the cold sore is a virus: the herpes virus HSV1, herpes simplex, or even the herpes virus HSV 2.

After a first contamination, which can go unnoticed, this virus is lodged in nerve cells of your body, and more particularly, in nerve fibers, located on the face, towards the mouth.

Under certain circumstances, this virus can "wake up", "express itself" and induce the formation of vesicles at the corner of the lip.

The potential triggering causes are multiple:

  • sun exposure,
  • tiredness,
  • a viral condition (cold, otitis ...),
  • fever,
  • a wound on the face,
  • a very cold or very hot weather ...

But sometimes, we do not find triggering cause.

I have a cold sore: how to react?

When you have a cold sore, some precautions should be taken to avoid this risk of transmission:

  • Avoid kissing anyone.
  • Be especially careful not to transmit this virus to a baby or to a pregnant woman.
  • Wash thoroughly and regularly with your hands.
  • Do not touch the cold sore.
  • Do not apply any product (gel, cream ...) not recommended by a doctor or pharmacist.
  • Do not rub your eyes (at the risk of contamination).
  • Do not share your bathroom linen or toothbrush.
