what are the differences between herpes simplex virus 1 and 2?

Usually location: Herpes simplex virus type 1 usually causes cold sores on the lips. Type 2 usually causes genital herpes. However, herpes virus is an equal opportunity virus, so type 1 sometimes causes genital herpes, and type 2 sometimes ends up causing lip sores, depending on what kinds of activities a person participates in. There is no cure, but anti-viral medications help treat and prevent recurrences.

Herpes: Hsv 1 is usually the cause of fever blisters and hsv 2 is usually the cause of genital herpes, but both can cross the waist line.
