Can herpes be transmitted without symptoms? Understanding asymptomatic transmission

When we talk about herpes, most people imagine visible blisters and sores. But what many people don't know is that herpes can also be transmitted – even when there are no symptoms. This type of transmission is called asymptomatic transmission, and it is an important reason why herpes is so widespread in the population.

 

In this blog post, we explain how asymptomatic transmission works, why it occurs, and what you can do to protect yourself and your partners.

What does asymptomatic infection mean?

"Asymptomatic" means that the person does not experience any symptoms – no sores, itching, burning or other discomfort. However, the virus can still be present on the skin surface and can be transmitted to others through contact.

With herpes, this means that a person without an outbreak can still shed virus for short periods of time – especially on the genitals or around the mouth.

How is herpes transmitted without symptoms?

Herpes viruses are transmitted through skin-to-skin contact – not necessarily through open wounds. This is most often done via:

• Vaginal, anal, or oral intercourse
• Kissing, especially if you have HSV-1
• Skin contact in areas with virus shedding

When the virus is reactivated from its “dormant state” in the nerve pathways, it can migrate to the skin surface without giving any obvious signs – and this is where asymptomatic viral shedding occurs.

How common is asymptomatic infection?

Research shows that:

• People with HSV-2 shed virus asymptomatically up to 10% of the days in a year.
• People with HSV-1 (genital) shed slightly less frequently, but still significantly.
• Many people are infected by a partner who did not know he/she had herpes.

This makes prevention difficult without open communication and protection.

How can the risk be reduced?

Although herpes can be transmitted without symptoms, there are several effective ways to reduce the risk:

1. Antiviral medication (e.g. valacyclovir)

Reduces the risk of transmission by up to 50% with daily use.

2. Using a condom

Provides extra protection, especially for genital herpes. However, note that herpes can also be found on areas of skin outside the condom's coverage.

3. Communication

Talk openly with your partner about herpes. Many people choose to get tested together.

4. Know your breakouts

Even if you don't have visible symptoms, you can learn to notice "tingling" or "burning" warning signs and avoid intimacy during these periods.

Conclusion

Yes – herpes can be contagious even when there are no visible signs. This is due to asymptomatic viral shedding, which plays a major role in the spread of herpes. But with knowledge, openness and preventive measures, it is possible to significantly reduce the risk – and live safely with or without the virus.
