The Herpes Simplex Virus, also known as HSV, is an infection that causes Herpes which leads to small, painful, fluid-filled blisters on the skin, mouth, lips, eyes or genitals. This infection is categorized into two types: Herpes Simplex Virus Type-1 (HSV-1) and Herpes Simplex Virus Type-2 (HSV-2). HSV-1 is a highly contagious and common infection that is mainly transmitted by oral contact in or around the mouth, causing cold sores/Herpes Labialis as well as Genital Herpes in some cases. On the other hand, HSV-2 is transmitted sexually (genital-to-genital, oral-to-genital, or genital-to-oral) and perinatally (mother to child). Both HSV-1 and HSV-2 infections are lifelong.
