As it shows the number of readers in recent years, many people with genital herpes, if not more concerned about the transmission probability distribution partners to their health. In addition, some oral herpes, share this concern. This is because one type is more effective than others?
Short answer: no. Both viruses spread easily to the site and the benefits that can spread to other sites. Both are highly contagious during active infection, but the virus often spreads when there is no recognizable symptoms. For Spruance, people with existing oral HSV-1 virus is spread in saliva, approximately 5% of the time, but show no symptoms. During the first year of illness, people with genital HSV-2 virus spreading genital area of approximately 60-10% of the days when they have no symptoms, and less with time. (Both figures are shown separately in the form of an identified viral culture.)
Then, however, is a complicated problem of transmission. Acquisition of type 1 is more complicated, but certainly possible if you have a different view. This is because all types of genital or oral contract, makes the body produce antibodies, some of which are effective against HSV-1 and 2 Acquired immune protection is more limited when the body begins the second type. If a person infected with herpes is the second type of contract, the first episode tends to be less stringent than previously, when there were no antibodies.
In practical terms, this means oral HSV-1 is frequently easier to get herpes infection. Usually the first herpes simplex virus that people face, oral HSV-1 generally applies only through the social nature of the kiss, the family gives the child. Because children are not the type of prior HSV infection, have no immunity.
Where are the teenagers and small, around 50% of Americans are HSV-1 antibody. Until the age of 50 years, approximately 80-90% of Americans HSV-1 antibodies.
For comparison, almost all HSV-2 occurs after childhood, when people become sexually active. Those who have HSV-1, acquired immune responses, reduce - though certainly not eliminate most of the risk of HSV-2. According to one study (Mertz, Annals of internal diseases, 1992), previous oral HSV-1 infection is reduced after acquiring HSV-2 by 40%.
Pre-contract oral HSV-1 infection reduces the risk of infection, HSV-1 and more. Studies show that genital HSV-1 infection is almost always occur in people who have HSV infection of any type (Corey, Annals of internal diseases, 1983).
In the absence of prior oral infection, but HSV-easy to use in the genital area, usually through oral sex. In some countries, like Japan and the UK, HSV-1 genital HSV-2 as often as, or more frequently.
"The prevalence of HSV-1 differs from the practice of oral sex, and percentage of people infected with HSV-1 in childhood," says Dr. Anna Wald, a researcher at the University of Washington in Seattle.
Finally, the issue of immunity and HSV types is complicated by additional questions. Some studies show that only certain nodes can acquire immunity to HSV by type of virus.
In the laboratory infection of ganglia with more than a real virus, believing it may be harder to obtain a second HSV type in a place where you have VHS. For genital HSV-1 infection, for example, may give greater protection against HSV-2 infection prior oral HSV-1.
What does this mean in practice? Let's look at some examples to understand. Say you have HSV-1 and your partner has genital HSV-2. If you have unprotected sex, is a small but real risk of getting HSV-two, leading to more outbreaks of faith. "We have registered cases, in which a person receives and HSV-2 genital HSV-1 infection," says Wald. "I do not think it happens often, but it happens."
Moreover, it is highly unlikely that your partner is genital HSV-1 from you. "I've never seen such a case, a person acquires HSV-1 in HSV-2," said Wald. "It's possible, but it would be unusual."
What to do if your partner has genital HSV-2 and oral sex with him / her? You get HSV-2 in the mouth? Given the widespread practice of oral sex (about three quarters of all adults practice in accordance with the social organization of sexuality, 1994) and incidence of genital HSV-2 infection can be expected that the terms oral HSV-2 is relatively common. This is not F.
According to one study, almost 100% of genital HSV-2 cognitive (Nahmias, Scandinavian Journal of Rheumatology Annex, 1990). One reason is that most adults are already infected with HSV-1 orally, which provide immunity against HSV-2 infection. Another reason is that oral HSV-2 rarely activated, so that even if an infection exists, nobody knows.
We have not discussed the transfer of HSV-1 or 2 in your favorite place. What about transfer elsewhere? Say you have genital HSV-1 through oral sex. It can transmit the virus sexually sex partner?
The answer is yes, but probably not as simple as it propagates through oral sex. The main reason is that the virus is activated, and she rarely out of their benefits. Only a quarter of people with genital HSV-1 virus spread in the absence of any symptoms, while 55% of people with HSV-2 did not (Wald, New England Journal of Medicine, 1995). "Editing the data seem to parallel recurrence data, meaning that people, many relapses in many departments," said Wald.
While HSV-1 can be transmitted from genital to genital, "We believe that more easily transmitted oral sex because HSV-1 more active in the oral region," said Wald. However, she warns that "the transfer of HSV-1 asymptomatic devoted to their culture." In other words, genital HSV-1 can be transmitted sexually, by sex, and even in the absence of symptoms. "Well," virus "Bad" Virus
If a herpes infection as easily transmitted orally to the genitals of both, so why do people take steps to prevent genital infection, but oral? Why do we kiss through dental dam?
"The irony is that right?" Wald said. "This is not health, but social recognition."
Scientists can tell us the whole day, the main difference between the two types of virus, only the place preference, either generally occur above and below the waist. But the unspoken attitude of our company to send another message. This is only a problem of social relations in a whisper. Below the waist is bad.
People think oral herpes as "good" herpes and genital herpes as "bad," says Glover of the National line of cold. " Part of it is that they are not informed about the similarities between HSV-1 and 2 But it is good and bad, as our views on sex and culture of our body.
One immutable fact is that HSV-1 is usually transmitted through contact with the lips and HSV-2 infection is usually transmitted through contact with infected genitals. From a social point of view, the problem is not a disease, how you arrived.
Whether we like it or not, prejudice the public against genital herpes, regardless of the virus that causes reality. "People are harder to explain a new partner who has genital herpes, although HSV-1 that had herpes," said Glover. "I just said the word" sex "as an anvil that pulls down the sentence.
Is this a problem doing crazy? For people who have problems related to public relations for genital herpes, blatant double standard society applies to oral herpes can be frustrating, to say the measurement.
