Although anyone is potentially at risk for contracting the Herpes simplex virus, anyone with a compromised immune system has a higher risk. Between 68-81 % of people with HIV also have Herpes simplex virus type 2. This is genital herpes. They can also be infected by type 1, or oral herpes. The virus enters the body via broken skin or through mucous membranes. The risk for infection is highest with direct contact of blisters or sores during a period of outbreak. Exchange of bodily fluids is a transmission method. Sometimes, a person may appear asymptomatic, but may be virus "shedding" and is still contagious at this time. Sexual contact with an infected individual can lead to the spread of Herpes simplex virus.
