Transmission
To infect people, the herpes simplex viruses (both HSV-1 and HSV-2) must get into the body through broken skin or a mucous membrane, such as inside the mouth or on the genital area. Each virus can be carried in bodily fluids (saliva, semen, fluid in the female genital tract) or in fluid from herpes sores. The risk for infection is highest with direct contact of blisters or sores during an outbreak.

Once the virus has contact with the mucous membranes or skin wounds, it begins to replicate. The virus is then transported within nerve cells to their roots where it remains inactive (latent) for some period of time. During inactive periods, the virus cannot be transmitted to another person. However, at some point, it often begins to multiply again without causing symptoms (called asymptomaticshedding). During shedding, the virus can infect other people through exchange of bodily fluids.

Sometimes, infected people can transmit the virus and infect other parts of their own bodies (most often the hands, thighs, or buttocks). This process, known as autoinoculation, is uncommon, since people generally develop antibodies that protect against this problem.

Transmission of Oral Herpes. Oral herpes is usually caused by HSV-1. HSV-1 is the most prevalent form of herpes simplex virus, and infection is most likely to occur during preschool years. Oral herpes is easily spread by direct exposure to saliva or even from droplets in breath. Skin contact with infected areas is enough to spread it. Transmission most often occurs through close personal contact, such as kissing. In addition, because herpes simplex virus 1 can be passed in saliva, people should also avoid sharing toothbrushes or eating utensils with an infected person.

Transmission of Genital Herpes. Genital herpes is most often transmitted through sexual activity, and people with multiple sexual partners are at high risk. The virus, however, can also enter through the anus, skin, and other areas.

People with active symptoms of genital herpes are at very high risk for transmitting the infection. Unfortunately, evidence suggests about a third of all herpes simplex virus 2 (HSV-2) infections occur when the virus is shedding but producing no symptoms. Most people either have no symptoms or don't recognize them when they appear.

In the past, genital herpes was mostly caused by HSV-2, but HSV-1 genital infection is increasing. This may be due to the increase in oral sex activity among young adults.
