Genital herpes is a disease caused by the herpes simplex virus (HSV), of which there are two types.
HSV-2 cannot survive long on a non-living surface, so there is no real risk of getting it from a toilet seat or hot tub, for example. If you are having trouble finding the information you are looking for, try using the search box. Virus can spread through direct contact with fluid from the rash blisters caused by shingles. The Shingles is less contagious than the chickenpox and the risk of a person with shingles spreading the virus is low if the rash is covered. Shingles is contagious and can be spread from an affected children, person to babies or adults who have not been chickenpox or have not had the chickenpox vaccine. Close, personal contact with open blisters passes the shingles virus from one person to another. Keeping the shingles rash clean and covered can help prevent spreading the virus to others who are at risk.

Two herpes virus particles are shown; they were prepared for transmission electron microscopy by the negative stain technique from the Wadsworth Center of the New York State Department of Health. The glycoprotein B (gB) is clearly visible in clusters of spikes of approximately 10 nm length.

When it's active, it travels to the surface of the infected area (skin or mucous membrane) and makes copies of itself. One reason may be that the virus can infect a woman's genitals more easily than it can a man's. HSV-1 can also spread from the mouth to the genitals during oral sex (fellatio, cunnilingus, analingus). But just as HSV-1 can infect the genitals and cause genital herpes, HSV-2 can pass from one person's genitals to another person's mouth, resulting in oral herpes.

In such case someone with shingles can pass the varicella-zoster virus to you, because you don’t have it in your body.
But the virus that causes shingles like the varicella zoster virus can be spread from a person with active shingles to another person who has never had chickenpox. While the blisters are fresh or oozing you’re considered contagious to people who haven’t had chickenpox or who have a compromised immune system. Vaccine reduces the risk of getting shingles and having the widespread nerve pain associated with it.

The top inserts show a computationally isolated hexon (blue), penton (yellow) and triplex (pink). Between the capsid and the envelope is an ill-defined layer of proteins, collectively known as the tegument.


Viral particles seen by transmission electron microscopy (TEM) at a magnification of 190,920x). This is called "shedding" because these new viruses can, at this time, rub off on another person.
Genital herpes is more common among blacks than it is among whites, and it becomes more common as people age.
In some cases, the person exposed to the virus might develop chickenpox but will not develop. Once they have chickenpox, a person cannot be catch virus (or contract the virus) from someone else. Herpes simplex virus infection becomes latent, that is it becomes invisible after a fever blister episode, but the virus persists, in ganglia at the floor of the brain, where when conditions are right it can re-emerge.

In the past, HSV-1 was not known to cause genital herpes, but that is changing, especially among people who begin having sex at a young age. Then the virus travels back down the nerve to a ganglion (mass of nerve tissue), usually at the base of the spine, where it lies dormant for a while. Nucleocapsid surrounded by the tegument that consists of globular material which is frequently asymmetrically distributed and may be variable in amount. Nucleocapsids sometimes penetrated by stain (although intact envelope impermeable to stain); 100-110 nm in diameter.
