Herpes and Partners: What CDC Advises About Sex, Condoms and Telling
Herpes and partners is a common worry because the virus can pass between people when no sore is visible. CDC says condoms lower the risk but do not remove it, and daily antiviral medicine lowers it further. Telling a partner before sex lets both people decide with facts. Reviralis, a supplement, is not part of that protection.

No sore, still possible01
Can you pass herpes without symptoms?
Yes. The virus can spread when there is no sore, no tingle and no rash, and many people carrying it have never had a noticeable symptom.
CDC says many people with genital herpes have no symptoms or very mild ones that go unnoticed or get mistaken for something else (CDC, About Genital Herpes). WHO says the virus can be passed on even when no sores are visible, and that HSV-1 is spread by kissing and shared items as well as sexual contact (WHO, Herpes Simplex Virus Fact Sheet). Mayo Clinic adds that cold sores are most contagious while a sore is weeping, though the virus can still spread at other times (Mayo Clinic, Cold Sore Symptoms and Causes).
That fact explains two things. A partner can be infected without ever being told by a sore. And a person can learn they carry the virus long after they caught it. Neither is a sign of cheating or blame. A clinician can order a blood test or a swab, depending on the situation.
What lowers the risk02
What lowers the chance of passing herpes to a partner?
Three things help: condoms, daily antiviral medicine for the person who carries the virus, and skipping sex when a sore or the first tingle appears. None reduces the risk to zero.
| Step | What it does | Limit |
|---|---|---|
| Condoms, used every time | Lower the risk of passing it on | Skin outside the condom can still touch skin |
| Daily suppressive antiviral | Lowers the risk to a partner, per CDC | Prescription only; some risk remains |
| No sex during symptoms | Avoids the most contagious time | Does not cover times with no symptoms |
| Testing and honest talk | Lets both people decide with facts | A negative test may not show recent contact |
CDC's treatment guidelines say suppressive therapy lowers transmission risk and that condoms reduce but do not remove it (CDC, STI Treatment Guidelines: Herpes). Combining the steps gives better protection than any one alone. Which mix suits two people is a conversation for them and a clinician. The antivirals guide explains how the daily plan works.
The conversation03
How do you tell a partner about herpes?
Pick a calm, private moment before sex, say it plainly, and bring facts. The facts are usually less frightening than the rumors.
Choose the time and place
Not in bed, not in a hurry, and not by text if you can avoid it.
Lead with the facts
Herpes is common. WHO estimates billions of people carry HSV-1 or HSV-2, and most have mild or no symptoms (WHO, Herpes Simplex Virus Fact Sheet).
Explain the steps you take
Say what you do about condoms, medicine and symptoms. Offer reading, such as the CDC and Mayo pages.
Give them room
A partner may need a day to think and may want to speak to their own clinician. That is a reasonable request.
This guide assumes nothing about you. Many readers come here with a partner, a test result, a family member or plain curiosity in mind. If a test is still pending, a clinician can explain what the result will and will not show.
Pregnancy04
What should partners know about pregnancy and herpes?
Tell the prenatal clinician early. Herpes passed to a newborn can be serious, and both CDC and WHO ask pregnant women to raise it with their care team (CDC, About Genital Herpes) (WHO, Herpes Simplex Virus Fact Sheet).
A clinician may talk through medicine late in pregnancy and the delivery plan. A partner's status can matter too, which is another reason to talk openly. Newborns with a fever, poor feeding, unusual sleepiness or blisters need urgent care, the same day.
Keep taking any prescribed medicine, including an antiviral, unless the prescriber tells you otherwise. See a clinician for a diagnosis because other conditions look like herpes. Call 911 for trouble breathing, a seizure, chest pain, swelling of the face or throat, or sudden confusion with a severe headache and stiff neck. Any eye pain, grittiness or sensitivity to light needs urgent care.

Does a supplement such as Reviralis protect a partner?
No source shows that. Reviralis Complete is a dietary supplement, and its label never mentions herpes, outbreaks or passing anything on to anyone.
The sales site uses words about outbreaks. We could not find a study of Reviralis, or of its 40 label names, showing that it changes how likely a person is to pass the virus on. CDC says antiviral medicine can lower the chance of passing the virus on, and we found no source saying a supplement does the same (CDC, About Genital Herpes). FTC rules also say a health claim needs competent scientific evidence behind it (FTC, Health Products Compliance Guidance).
If you take Reviralis for its vitamins and minerals, that is a separate decision, covered on the medicine check page and in the supplements and herpes guide. Do not count it as a protective step with a partner.
Getting care06
When should you see a clinician about herpes and partners?
See one for a diagnosis, before starting a new relationship if you have questions, during pregnancy, or any time symptoms are severe, spread widely or last more than two weeks (Mayo Clinic, Cold Sore Symptoms and Causes).
- A first outbreak, or a sore you cannot nameSee a clinician. A test can tell herpes from other causes, and early antivirals work best.
- A sore in or near the eye, or eye pain or blurry visionGet care the same day. Herpes in the eye can threaten sight.
- A weak immune system, or outbreaks that are severe or slow to healTell your clinician. People with weakened immunity can have longer, deeper outbreaks and may need a different plan.
- Pregnant or about to give birthTell your obstetric clinician. HSV can pass to a newborn at birth, and your team has steps to lower that risk.
- A newborn with sores, fever or poor feedingCall the pediatrician right now. Call 911 if the baby is limp, very hard to wake or struggling to breathe.
- Call 911 nowTrouble breathing, a seizure, chest pain, swelling of the face or throat, or sudden confusion with a severe headache and stiff neck.
From CDC (CDC, About Genital Herpes), Mayo Clinic (Mayo Clinic, Cold Sore Symptoms and Causes) and WHO (WHO, Herpes Simplex Virus Fact Sheet). This list is not complete, and a supplement is never a reason to wait.

FAQ07
Herpes and partner questions
Can herpes spread when there are no sores?
Yes. CDC and WHO both say the virus can pass between people when no sore is visible, and many carriers never notice symptoms. That is why condoms and daily medicine are suggested even in quiet periods.
Do condoms fully block herpes?
No. CDC says condoms reduce the risk but do not remove it, because the virus lives on skin that a condom may not cover. Used every time, they still lower the chance a great deal compared with no protection.
Does daily antiviral medicine protect a partner?
It lowers the chance, according to CDC, but not to zero. It is a prescription decision made by a clinician. Pairing it with condoms and avoiding sex during symptoms gives the best protection.
When should you tell a partner about herpes?
Before sex, when both of you can talk calmly. Telling early lets a partner ask questions, see their own clinician and decide with facts. There is no rule on exact timing, but earlier is kinder.
Can you get herpes from kissing?
Yes, HSV-1 can pass through kissing and shared items, and it can spread even when no cold sore is visible, according to WHO.
Is herpes a reason to avoid dating?
No. WHO says billions of people carry HSV-1 or HSV-2, and CDC says outbreaks tend to lessen over time. With a diagnosis, a care plan and honest talk, many people have healthy relationships.
