Is OB frequency linked asymptomatic shedding frequency?

Is there any data that correlates OB frequency with asymptomatic shedding for HSV 1 genitally?

More specifically, I have had HSV 1 genitally for 12 years with only one (initial) OB. What is the percentage of shedding based on that scenario?

...explains viral shedding in detail. The whole idea is there are no symptoms with shedding - the virus is active and can be transmitted, but the person is asymptomatic.

That makes sense. If there was a study I would participate. I have read on here from Dr HHH that shedding with genital HSV 1 is not likely, and that he's never seen a case of HSV 1 genitally being passed on.

Still, it would be nice to know for sure personally. Is there any feeling that goes along with shedding?

no studies on hsv1 genital transmission rates because it only sheds about 3% of days and far too many folks have hsv1 orally already. Too hard to find folks to even participate and too expensive to do the studies because you'd have to do them very long term because of the low shedding rates.

Disappointing from a patients point of view, realistic from a scientific point of view.

Here are the stats, but again they're for HSV2 (which you can still get, even with having HSV1)...

Here are odds based on female to male transmission of genital herpes.

FEMALE TO MALE RATE OF TRANSMISSION (HSV2 ONLY STATS IS NOT APPLICABLE FOR HSV1)

If you have 100 couples where the female has HSV2 but not the male (these figures are over a year) the odds of female to male transmission are, if you do nothing other than avoid sex during an outbreak, 4 men out of a 100 will get herpes in a year, or 4%. If you do go on a suppressive therapy then it drops to 2 men out of a 100 in a year, or 2%. And if you use suppressive and a condom the chances are 1 man out of a 100 will get herpes in one year or 1%.

The Valtrex and transmission study stats are based on having sex 2 times/week.

And, here are the stats for male to female transmission rates:

MALE TO FEMALE TRANSMISSION RATES (HSV 2 ONLY STATS IS NOT APPLICABLE FOR HSV 1) If you have 100 couples where the male has HSV 2 but not the female (these figures are over a year) the odds of male to female transmission are if you do nothing (other than avoid sex when there is an outbreak) 8-10 females out of a 100 will get herpes in a year, or 8-10%. If you do go on a suppressive therapy then it drops to 4-5 females out of a 100 in a year or 4-5%, and if you use suppressive therapy and a condom the chances are 2-3 females out of a 100 will get herpes in one year, or 2-3%.

The Valtrex and transmission study stats are based on having sex 2 times/week.

The Valtrex studies are for HSV2 only. You can google it and find it on the clinicaltrials.gov site, and the GlaxoSmithKline (GSK) site as well.

That's exactly what happened to me. My partner had cold sores badly as a child. By the time I was with him he hadn't had them in years. I never noticed any cold sores on him.  

When I had the initial OB, I assumed there was only one type that could be "down there"... HSV 2. It took 10 years for me to not feel "dirty" and finally research and get tested. After learning, I felt reborn. It's really not a big deal, it's manageable and does not make someone "dirty." That took me a long time to get over.

In the future, I will ask STD status including oral HSV.

I'd be interested in that statistic too (I enjoy stats). I have heard it's more difficult for a male to acquire HSV in the genitally area. But I am not sure why or if it's true. There's a lot of conflicting info on the nets.  This forum is great though!

No studies for HSV1 transmission? Really? That seems medically irresponsible on behalf of modern science lol.
No information on the likelihood of a girl with HSV1 orally, giving it to a guy genitally through oral sex?

There are no studies for HSV1 transmission. But, you already have it, so no worries there. Having oral herpes gives you significant protection against getting it genitally.

Good point! If you don't even know you have herpes, it doesn't matter how honest you are.

I've gotten cold sores on my mouth since I was a kid, but I never think to ask a person if they've ever had a cold sore before kissing them or performing oral sex.

Do you know what the rate of female to male oral to genital transmission of HSV 1 is?

Agreed, worried. The caveat is, of those infected with genital herpes, only 90% even know it to begin with!! So honesty really doesn't fit in the equation if you don't know you have it to begin with!

yogini, I have genital HSV1 as well. My BF had cold sores as a teen (we're both in our forties), but in the five years we were together, he never had one. Neither of us knew he could transmit oral to genital via viral shedding.

Still, it has little impact on my life - I never ever think about it, and I haven't had an OB in almost a year. Only if I become involved with a new partner will it need to be dealt with.

@petal:

Interesting stats, thank you. That seems correct. I didn't have any HSV 1 until I was 18. And if i knew it could be passed from mouth to genitals, I'd still be negative. I think that there are many misconceptions about HSV 1 and 2, like I had. Thinking that cold sores cannot be transmitted.

Thanks for clarifying petal. You're absolutely right, statistics are hard to go by, since they always vary by age, race, geographic location, lifestyle etc.

The best policy is always to be honest with someone you sleep with!

Thanks for the info.

Yes, you're right. I find it...is funny the word...that I was always very freaked out about getting a cold sore from someone by kissing so I avoided that; then ended up with HSV 1 genitally! D'oh!

I didn't know that was even possible. Thought the two viruses were completely different and not transferable.

Anyway, thank you for the reply. Maybe someday technology will allow for a home test to show when shedding (orally or genitally).

Actually worried, this is incorrect. About 1/3 of all new genital herpes cases are HSV1, and amongst college-aged folks, it's over half. Oral sex is the huge majority of this transmission. Also, "most people already have HSV1" isn't accurate either... the rates of oral HSV1 vary by age, and obviously grow with age too. While over half of people my age (I'm 45) have oral HSV1, it's actually well below 50% for a college-aged person.

yogini3, shedding doesn't correlate with OBs. Folks who've never even had a recognizable OB (HSV1 or 2), still shed about the same as those who have frequent OBs. Here are the shedding stats from the Herpes Handbook, a great resource:

I'm not an expert, but I'm pretty sure most studies do not show a correlation between your amount of outbreaks and asymptomatic shedding. In other words, people who have no outbreaks could still shed asymptomatically as much as someone who has a lot.

To make matters worse, there is no way to know when you are asymptomatically shedding. But if you think about it, do people wonder before they kiss someone if they are asymptomatically shedding HSV1 orally? No, because most people already have it, and the transmission rate is so low.

Thanks for the reply.

I am not speaking in specifics about anyone but me. It's more of a general inquiry.

I wouldn't be too concerned if a partner was HSV 1 positive. I am wondering the stats assuming partner HSV 1 negative.

However, I'm really just curious as to whether OB frequency is related to shedding frequency.

If you have HSV1 your chances of spreading it genitally to another person are very low since most people already have HSV1 on their mouths. Its impossible to be infected with HSV1 genitally if you already have it orally.

If you're worried about a specific person, have them get tested for oral herpes to see if they're even at risk of catching it form you. :)
