Should I disclose oral herpes before kissing?

This is a question brought up a lot on the Herpes Opportunity forums.

“Should I disclose that I get cold sores to potential partners before kissing them?”

Which way to go on this can be a confusing one, simply because it’s up to the individual on what feels right.

So let’s get into this question a bit deeper, shall we?

The reason this conversation is a bit hard to pin down is because when it comes to oral herpes (almost always HSV-1) specifically, 47% of Americans 14-49 years old have it. Now that’s about half the people in that age group, isn’t it?. So considering this statistic, who holds the responsibility of bringing up the topic? (In a perfect world, we all would be talking about every aspect of our sexual and intimate histories with each other before getting intimate at all, but that ain’t the world we live in.)

Here’s another way to think of this without herpes specifically as the topic … Here’s the scenario: Five out of 10 people in a room are sick with the flu virus. All 10 people know before walking into the room that half of the people in that room are sick with the flu. Which group should be covering their mouths? The 5 people who are sick or the 5 people who aren’t? You’ll find people to argue either point. What it comes down to is this: What does your integrity tell you to do considering the circumstances? Would you feel guilty if you kissed someone without telling them you are a carrier of oral herpes (cold sores)? (Of course it goes without saying that if you're having an actual active outbreak that you don't kiss people.)

My personal opinion is we just have the conversation, regardless of whether or not herpes is on the mouth or genitals. It’s still an opportunity to have an important conversation and care about someone else’s health. Imagine if before we even kissed, a nonchalant “Hey, just FYI I get cold sores (just like about half of everyone) and just wanted to let you know. Do you get cold sores?” Doesn’t have to be a dealbreaker-feeling conversation. No shame. No guilt. No weirdness. Just a simple conversation about herpes. No biggie. That’s the world I want to live in. Where everyone can talk openly about something simple like herpes so it can open the door to deeper conversations and deeper connection.

"Yeah, but what about kissing ‘down there’?" (Nudge, nudge)

This leads to the obvious next question that’s asked … what about herpes and oral sex? You see, this is where this discussion gets fascinating (as far as I’m concerned). Why? Because what if someone has oral HSV-1 (read about the differences between HSV-1 and HSV-2) and that person goes down on their partner then the HSV 1oral infection, with or without symptoms,  could be transmitted to the genitals of their partner, if they don’t already have HSV 1.  The reverse is unlikely to happen – if someone has genital HSV 1 and someone who doesn’t have HSV 1 gives them oral sex, the virus is far less likely to be transferred to the mouth of the uninfected person.  The reason that’s true is because HSV 1 genitally is rarely active, especially after someone has been infected for a year or two.

This confusing double standard between no shame in oral herpes, but too much shame in genital herpes is proof positive to me that our culture has a severe sexual shaming problem. The fact that we get something through kissing doesn’t have any stigma, but if we get something through expressing ourselves sexually, that's shameful? Time to realize that sex is a natural, beautiful thing. No shame belongs in sex.

Whether it's oral or genital herpes, disclosure doesn't have to be a big dramatic event. This video explores the idea of a "pre-disclosure" — those natural moments that open the door to the conversation.

Frequently asked questions

Should you disclose HSV-1 before kissing?+
There's no law that says you have to, but about 48% of Americans ages 14-49 already have oral HSV-1, and most got it as kids through totally non-sexual contact. That said, if you know you get cold sores, a simple heads-up is a small act of care that can open the door to deeper connection. It doesn't have to be heavy.
Do you have to tell someone you have cold sores?+
Legally, no — there are no U.S. laws requiring disclosure of oral herpes before kissing. Medical guidance from the CDC and ASHA recommends avoiding kissing and sharing utensils during active outbreaks, since that's when the virus is most contagious. Between outbreaks, there is still a small risk from asymptomatic shedding. Have the conversation — it's a chance to show you care about someone's wellbeing.
Can you pass cold sores to your children by kissing them?+
Yes, oral HSV-1 can be transmitted to children through kissing, especially during or near an active cold sore outbreak. Many people actually acquire HSV-1 in childhood from being kissed by a family member with the virus. To reduce the risk, avoid kissing your child on or near the mouth when you have an active cold sore, and wash your hands frequently during outbreaks. It's also important not to share utensils, cups, or towels during an active outbreak.
Is disclosing oral herpes (HSV-1) as important as disclosing genital herpes?+
This is a personal and ethical question many people wrestle with. Since oral HSV-1 is extremely common (about 50-67% of the global population carries it), many people don't think twice about cold sores. However, oral HSV-1 can be transmitted to a partner's genitals through oral sex, causing genital herpes. For that reason, many people feel it's important to mention it, particularly before oral sex, even if the stigma around cold sores is much less than genital herpes.
Can you transmit cold sores when you don't have a visible sore?+
Yes, oral herpes can be transmitted even when no cold sore is visible. This is called asymptomatic shedding, where the virus is active on the skin surface without causing noticeable symptoms. Shedding is most frequent in the first year after infection and tends to decrease over time. The risk is highest during and just before an outbreak, but because shedding can happen at any time, there is always a small possibility of transmission.
