It doesn't go from HSV-1 (associated with the mouth) to HSV-2 (associated with the genitals) just because it is on the genitals. You can transfer mouth herpes to the genitals. If it is HSV-1 that the person has on their mouth and performs oral on someone the person receiving can get genital herpes but it would be HSV-1. It is harder to get HSV-1 on the genitals then it is to get HSV-2 on the genitals because each version of the virus has different sites of preference. HSV-1 virus prefers the mouth while HSV-2 prefers the genitals. I know it is confusing. The basic answer to your question is yes. If you have any questions, then feel free to ask me.

I got clinically diagnosed with the herpes simplex virus (type 2) about six years ago, when I was still attending college and had a stupid one-night stand. I just made a massive mistake that one time and suddenly I felt like I was going to have to live with the consequences for the rest of my life. The worst part was feeling I could never date guys again. In the end, who wants to go out with someone that has sores around her you-know-what? But since a friend shared this video everything changed https://tr.im/herpesCure201571X9

Not only was I able to clear away all traces of the hsv from my body in less than 21 days, but I was also able to begin dating once more. I even met the man of my dreams. This method provided me the opportunity to be happy and experience real love. Now I want to enable you too by sharing this with the whole World.

Yes. Absolutely. If person X is having an outbreak of herpes (cold sore) and they give oral sex to person Y, person Y can certainly contract the disease. They are actually two different strains of the virus but it's definitely translatable. Also, something that is not widely understood, the virus has the potential to remains active (alive) for several hours after contact (eg. you touch your cold sore, then touch someone else, they can get it). Good luck and be safe!

herpes 1 is the sore in your mouth/lips. Herpes type 2 is the genital herpes. they're both caused by the same vuris herpes simplex. Yes you can catch that sore in the mouth-but the mouth sore can not turn into an STD(sexually transmitted disease).

How Easily Spread?

(sorry this is long but it's very interesting)

As a number of readers have attested over the years, many people with genital herpes are at least as concerned about transmission-the likelihood of spreading the virus to a partner-as about their own health. On the other hand, few people with oral herpes, share this concern. Is this because one type is more contagious than the other?

The short answer is no. Both viral types are easily transmitted to their site of preference, and can also be spread to other sites. Both are most contagious during active outbreaks, but are often spread through viral shedding when there are no recognizable symptoms. According to Spruance, people with recurrent oral HSV-1 shed virus in their saliva about 5% of the time even when they show no symptoms. In the first year of infection, people with genital HSV-2 shed virus from the genital area about 6-10% of days when they show no symptoms, and less often over time. (Both of these figures reflect shedding as detected by viral culture.)

From here, however, the question of transmissibility gets more complicated. Acquisition of one type is more difficult-though certainly possible-if you already have the other type. This is because either type, contracted orally or genitally, causes the body to produce antibodies, some of which are active against both HSV-1 and 2. This acquired immune response gives some limited protection if the body encounters a second type. When a person with a prior HSV infection does contract the second type, the first episode tends to be less severe than when no prior antibodies are present.

On a practical level, this means oral HSV-1 is often the most easily acquired herpes infection. Usually the first herpes simplex virus that people encounter, oral HSV-1, is typically spread simply by the kind of social kiss that a relative gives a child. Because children have no prior infection with any HSV type, they have no immune defense against the virus.

By the time they're teenagers or young adults, about 50% of Americans have HSV-1 antibodies in their blood. By the time they are over age 50, some 80-90% of Americans have HSV-1 antibodies.

By comparison, almost all HSV-2 is encountered after childhood, when people become sexually active. Those who have a prior infection with HSV-1 have an acquired immune response that lowers - though certainly doesn't eliminate-the risk of acquiring HSV-2. According to one study (Mertz, Annals of Internal Medicine,1992), previous oral HSV-1 infection reduces the acquisition of subsequent HSV-2 infection by 40%.

A prior infection with oral HSV-1 lowers the risk of acquiring genital HSV-1 even further. Studies show that genital HSV-1 infections almost always occur in people who have no prior infection with HSV of either type (Corey, Annals of Internal Medicine, 1983).

In the absence of prior oral infection, however, HSV-1 spreads easily to the genital area, usually through oral sex. In some countries, such as Japan and parts of Great Britain, genital HSV-1 is as common as genital HSV- 2, or more common.

"Prevalence rates of genital HSV-1 differ based on the practice of oral sex and on the percentage of people who are HSV-1 positive from childhood," explains Anna Wald, MD researcher at the University of Washington at Seattle.

Finally, the question of immunity and HSV types is complicated by an additional issue. Some studies suggest that the ganglia themselves may acquire some immunity to HSV after they are exposed to one viral type.

In the laboratory, infection of ganglia with more than one virus is difficult, suggesting that it may be more difficult to acquire a second HSV type in a location where you already have HSV. A prior genital infection with HSV-1, for example, may give more protection against genital HSV-2 than a prior oral infection with HSV-1.

What does all this mean on a practical level? Let's look at some examples to find out. Say you have genital HSV-1 and your partner has genital HSV-2. If you have unprotected sex, there is a small but real risk that you will get HSV-2, resulting in more outbreaks and more shedding. "We have documented cases where a person acquires HSV-2 after a prior genital HSV- 1 infection," says Wald. "I don't think it happens often, but it does happen."

On the other hand, it's very unlikely that your partner will get genital HSV- 1 from you. "I've never seen a case of a person acquiring HSV-1 on top of HSV-2," says Wald. "It's possible, but it would be unusual."

What if your partner has genital HSV-2 and you perform oral sex on him or her? Will you get HSV- 2 in the mouth? Given the widespread practice of oral sex (some three-quarters of all adults practice it, according to The Social Organization of Sexuality, 1994) and the prevalence of genital HSV-2 infection, you might expect oral HSV-2 to be relatively common. It's not.

According to one study, almost 100% of recognizable HSV-2 infection is genital (Nahmias, Scandinavian Journal of Infectious Diseases Supplement, 1990). One reason is that most adults are already infected with HSV-1 orally, which provides some immunity against infection with HSV 2. Another reason is that oral HSV-2 rarely reactivates, so even if an infection does exist, no one knows.

So far we've been talking about transmission of HSV-1 or 2 from its site of preference. What about transmission from another site? Say you acquire genital HSV-1 through oral sex. Can you spread the virus to a partner through genital sex?

The answer is yes, but probably not as easily as it was spread through oral sex. The main reason is that the virus reactivates and sheds less often outside its site of preference. Only about one quarter of people with genital HSV- 1 shed virus at all in the absence of symptoms, while 55% of people with HSV-2 do (Wald, New England Journal of Medicine, 1995). "Shedding data appear to parallel recurrence data, meaning that people who have a lot of recurrences also have a lot of shedding," says Wald.

While HSV- 1 can be spread from genitals to genitals, "we think it is spread more easily through oral sex because HSV-1 reactivates more frequently in the oral area," says Wald. However, she warns, "transmission of genital HSV-1 during asymptomatic shedding has been documented." In other words, genital HSV-1 can be spread through genital sex, even when there are no symptoms. "Good" Virus/ "Bad" Virus

If HSV infection is as easily transmitted from the mouth as from the genitals, then why do people take steps to prevent genital but not oral infection? Why don't we kiss through dental dams ?

"It's ironic, isn't it?" says Wald. "It's not about health, it's about social acceptability."

Scientists can tell us all day that the main difference between the two viral types is simply their site of preference-whether they typically occur above the waist or below. But the unspoken attitudes of our society send a different message. That's just the problem, social attitudes whisper. Below the waist is bad.

The inescapable fact is that HSV-1 is usually spread through contact with infected lips, while HSV-2 usually spread through contact with infected genitals. From a social point of view, the problem is not the disease; it's how you got it.
