Herpes simplex is contagious, and the herpes simplex virus is mainly transmitted through direct contact and indirect contact. 1. Direct contact: including kissing, sexual contact, contact with lesion secretions, etc., is a common mode of transmission of the herpes simplex virus, and adults who have chaotic private lives and are sexually active have a high chance of being infected. 2. Indirect contact: sharing dishes, cutlery, cups, towels and other household items with a person with herpes simplex may be infected with the herpes simplex virus. If you have herpes simplex patients around you, remember to isolate them and avoid direct or indirect contact with the pathogen. If you have symptoms of herpes simplex or have a clear history of contact with the patient, remember to go to a regular hospital for examination.
