I just have a quick question about herpes transmission. It might sound ridiculous but I'm really confused. I know herpes can be transmitted from skin to skin contact but what I'd like to know is does this mean any where on the body or is it only limited to the genitals area ? I mean if I touch the private area of a woman and she has HSV, is there any risk of me catching it from JUST touching here there and if not, how is it that the virus is only transmitted thru skin to skin contact (of genitals) and not other areas on the body? Just curious since skin is skin.
Hi Island_man1
Good question.
The herpes simplex virus (HSV) can be transmitted to any part of the body. It eventually lies dormant in nerve cells.
The thing with HSV is that it can only gain entry through a weak spot in the skin or a mucous membrane (which doesn't have the hard outer layer of skin). Mucous membranes like the lining of the mouth, inside of nose, urethra in guys, rectum, vagina and the inside of the inner labia minora (small lips).
The skin of the hand has a strong outer layer which the HSV cannot get through unless you have a break in the skin. A common area to have a break in the skin on the hands is around the finger nails e.g. Hang nails, biting the nails. A herpes infection on the finger tips is called herpes whitlow and is something you used to see on dentist and health care workers doing mouth care until gloves were used.
Another way to get breaks in skin is from the act of sex, with the genitals grinding together you end up with little microscopic tears on the skin which allows the virus to get into the body.
To answer your question if you were fingering a woman who had HSV and you had a cut on your hand I guess it could pass to your finger. The reason it is not passed from contact with other body parts is that these body parts typically don't come in contact with the mouth/genitals or the skin is thick enough that we don't see HSV passing.
To summarize
(1) HSV can infect any part of the outside body.
(2) For HSV to spread you must come in contact with an area that could have HSV on it. Given how HSV typically spreads this area is usually around the mouth or the genital area.
(3) After coming in contact with HSV, the virus needs to enter the body, it can't get through unbroken skin so it tends to get in the body through the weaker mucous membrane or through broken skin.
Let me know if this does not make sense.
