Emma is right.
HSV2 is mostly spread from genital to genital or anal contact. 90%+ of the time it infects the genital region (i.e. boxer shorts area). It infects the skin and transfers to the nerves where it becomes dormant except during an outbreak with lesions or silent asymptomatic recurrence. HSV2 is found on the skin 10% approximately of the time if the person is infected genitally.
However, transmission does not always occur with skin contact. HSV is not good at penetrating normal skin. It can more easily infect the genitals, anus, mouth, or eyes. It can also pass through skin that is damaged from trauma, abrasion, eczema, etc.
HSV2 rarely infects other parts of the body like the mouth, hands, or other areas. However, when those areas are infected, the recurrence rate is very low.
High friction contact (e.g. wrestling) can transmit HSV to previously normal skin. HSV1 is sometimes transmitted in this fashion, but HSV2 transmission would be uncommon.
HSV does not survive well outside of the human body. However it can exist for a period of time on towels and razors. Therefore they should not be shared (among people in general) or especially when someone has an infection and/or experiences symptoms. Soap and hot water (i.e. washing hands) are an effective means of killing the virus.
People with HSV2 typically do not transmit it through non-sexual contact with partners, friends, children, etc. Such transmission would be extremely rare. (In fact if a child has HSV2, it is commonly looked upon as an indicator of sexual abuse.)
Knowing the HSV2 status of your partner helps. Ask before you have sex and get mutually tested if it makes sense (e.g. multiple past partners, suspicious symptoms, or a past partner with HSV2). Most transmission occurs when people do not know that they have HSV2. Those that know they have HSV2 can better prevent transmission:
a. Abstinence when outbreaks occur. In a monogamous couple that has sex regularly for an entire year, transmission from male to female occurs in 11% each year. It is less from female to male.
b. Using condoms can reduce transmission
c. Using Valtrex can cut transmission rates by 50%. Other antiviral medication may be just as good. However studies have not been performed. Most people assume that the others work too.
d. Using (a), (b), and (c) are highly effective with very low annual transmission rates < 5%.
Thanks you so very much, i was just wondering on how it was spread and the risk factor behind it.
HSV-2 is usually spread through sexual intercourse. A condom will provide good protection, but is not 100% effective because the entire genital region is not covered and herpes can be spread through skin-to-skin contact. Oral sex is low risk for HSV-2 infection. Hope this helps.
