What Causes Cold Sore?
Herpes in the mouth/cold sore is caused by [4] the herpes simplex virus type I, often infection occurs in childhood. It is worth noting that the infection persists throughout life. The herpes virus is transmitted through the surface of the mouth and facial skin. The manifestation of rashes and relapses during life often provokes a reduced and weakened immunity. In order not to get infected with the herpes simplex virus, you should avoid kissing and contact with the saliva of people who have rashes in the mouth. Adequate sleep, a balanced diet, and a well-developed immune system that maintains normal vitamin D3 levels will help prevent relapse. If herpes is activated often – more than twice a year – or the rash is profuse, you should see a doctor.
