Herpes simplex mainly refers to herpes simplex, which usually clears up in about 10 days. Herpes simplex is a skin manifestation caused by infection of the skin and mucous membranes with the herpes simplex virus. It is mainly concentrated in the mouth, lips, perianal area or other areas where the skin and mucous membranes meet. The disease is self-limiting but prone to recurrence. If left untreated and gradually regulated by your own immunity, it will generally disappear in about 10 days. However, it should be noted that until the herpes disappears completely, the local skin surface may show symptoms such as pain and burning, and contact with certain dirty things may cause secondary bacterial infections, which may aggravate the existing disease and affect the self-healing time. It is advisable to use antiviral drugs under the guidance of a doctor to shorten the healing time, prevent secondary bacterial infections and systemic spread, and reduce recurrence.
