Herpes is an infectious disease caused by the Herpes Simplex virus, characterized by fluid-filled blisters on the skin and mucous membranes, and is transmitted through direct contact. The virus is acquired through direct contact with an infected individual, such as kissing, sexual intercourse, or sharing contaminated towels/items.

Viruses enter the body through micro-fissures in the skin or mucous membranes. They infect nerve cells, travel along nerve fibers, and establish themselves in nerve centers called ganglia. Remaining latent (dormant) in these centers, they can be activated by specific triggers and begin to form characteristic lesions on the skin or mucous membranes in the affected area. Current treatments do not completely eliminate the virus; instead, they aim to reduce the severity and frequency of symptoms or prevent lesion formation.
