A recent study showed that there are some genetic factors that have a major role in the incidence of “cold sore”. with this disease.
There are three genes that are inherited from one generation to the next, and these genes are closely related to the occurrence of the herpes virus reproducing itself inside the cells, and thus the emergence of the “cold sore” disease. [10]
Other causes include infections in the respiratory system, exposure to cold air, and emotional and physical stress.
Patients with this disease recover within 12 days after the onset of symptoms.
