[Question #5236] HSV 1 - Genital Type Important questions

22 months ago
I have genital herpes ( HSV 1 type) and was diagnosed about 1 year ago.  I only had one outbreak I am assuming I got infected with my last serious relationship but he never agreed to be tested. As I begin to date now I have disclosed the info and have had some that didn't care and others that did.  My questions are:

1) Can I transmit HSV 1 (genital type) orally? Meaning can I get to know someone and kiss them without worrying about transmitting HSV 1 genital?  Thus far I have disclosed even before kissing.  If I have genital type HSV 1 can I give oral sex to a man without worrying about transferring the virus?

2)  If the person is ok with it what are the asymptomatic transmission rates for HSV 1 genital type? 

3) Should I be taking Antiviral meds before sex or even before kissing? And if so how often and how much? 

4) If my partner gives me oral sex what is the asymptomatic transmission rate and could he then get HSV 1 oral type?



Thank you!

If you have this infection genitally, you are not infectious from your mouth and there is no need to disclose this before kissing or giving oral sex.

2)  If the person is ok with it what are the asymptomatic transmission rates for HSV 1 genital type?

We don't have that specific number.  it is likely 1/3 of what it is for HSV 2, HSV 2 sheds on about 14% of days and HSV 1 about 5% of days.

3) Should I be taking Antiviral meds before sex or even before kissing? And if so how often and how much?

Not before kissing - if you want to take it for transmission, it would be 500 mg of valacyclovir once a day or acyclovir 400 mg twice a day

4) If my partner gives me oral sex what is the asymptomatic transmission rate and could he then get HSV 1 oral type?

we don't have those numbers, I'm afraid.  But if this person has ever had a cold sore, they are extremely unlikely to get it in a new location.

Hello Terri! 

Thank you so much for your answers! This is very helpful! Please help me clarify your answers for number 2 & 3 below


2) "We don't have that specific number.  it is likely 1/3 of what it is for HSV 2, HSV 2 sheds on about 14% of days and HSV 1 about 5% of days."

What does 5% mean? 5% out of each year??

3) "Not before kissing - if you want to take it for transmission, it would be 500 mg of valacyclovir once a day or acyclovir 400 mg twice a day"

When would I start taking these meds before sex? 24 hrs?  
Do most people with this type take meds even when using condoms?

Thank you!!!!!!!

Sorry I thought of one more thing. If I ever have an outbreak again, how long after it clears up should I wait to have intercourse?

5% of days of swabbing - so 5 days out of 100

3) "Not before kissing - if you want to take it for transmission, it would be 500 mg of valacyclovir once a day or acyclovir 400 mg twice a day"

When would I start taking these meds before sex? 24 hrs? 
Same - 5 days

I don't know the answer to that honestly.

If you have another outbreak, wait to have sex until new skin has replaced the lesion.  But remember but you could shed virus when you have no symptoms that you recognize.

Thank you so much Terri for your quick response! Just to clarify , So 5 days before intercourse? Does it work if I only take it a few days before or even 24 hours before?

It will work some but that is definitely not optimal.
