Shortly after exposure to the virus, a newly infected person may develop fluid-filled blisters (vesicles) or pus-filled bumps (pustules), occurring singly or in a group.
Furthermore, these tender sores may come back periodically in the same sites.
Infections with the herpes simplex virus are very contagious and are spread by direct contact with the skin lesions. HSV Type 1 (HSV-1) infections usually occur around the mouth, lips, nose, or face, while HSV Type 2 (HSV-2) infections usually involve the genitals, lower back, or buttocks.
Herpes simplex infection of the lower back and buttocks—also called sacral herpes simplex or genital herpes—is a common recurrent skin condition associated with infection by the herpes simplex virus (HSV).
HSV infection usually appears as small blisters or sores around the mouth, nose, genitals, buttocks, and lower back, though infections can develop almost anywhere on the skin.
Because it so contagious, HSV causes a primary infection in most people who are exposed to the virus.
However, only about 20% of people who are infected with HSV actually develop visible blisters or sores.
HSV-2 infections are transmitted sexually or from a mother's genital tract to her newborn baby.
HSV-2 is often spread through direct skin-to-skin contact with active lesions on another person.
Appearing 2–12 days after a person's first exposure to HSV, the sores of a primary infection last about 1–3 weeks.
