It’s a common misconception that you can only have herpes if you’ve had an outbreak. In reality, most people with herpes never experience noticeable symptoms. This condition is called asymptomatic herpes, and it’s one of the main reasons the virus is so widespread.
Whether you’ve tested positive without symptoms or are wondering about a past exposure, this guide will help you understand how asymptomatic herpes works and what it means for your health and relationships.
What Is Asymptomatic Herpes?
Asymptomatic herpes refers to cases where a person is infected with HSV-1 or HSV-2 but does not experience any recognizable symptoms. These individuals may still test positive on a herpes blood test—even if they’ve never had an outbreak.
Some people go years without any symptoms. Others may have such mild irritation or tingling that it’s mistaken for something else, like razor burn or a yeast infection. Even without obvious signs, the virus remains in the body and can still be transmitted to others.
What Is Asymptomatic Shedding?
Even without symptoms, the virus can be present on the skin. This is called asymptomatic shedding, and it happens periodically without warning. During these times, herpes can be spread through skin-to-skin contact—especially in the genital or oral areas.
Asymptomatic shedding is one reason why herpes is often passed between partners who have no idea they’re carrying the virus. It can happen even in the absence of visible sores or irritation.
Can You Still Test Positive?
Yes. Herpes blood tests detect antibodies to HSV-1 or HSV-2, not the virus itself. These antibodies develop after infection—even if you’ve never had symptoms—and usually remain in your system for life.
If you test positive for herpes but haven’t noticed any symptoms, it simply means your body has responded to the virus. You may have contracted it years ago, or from a partner who was also asymptomatic.
Both STDCheck and myLAB Box offer testing that can detect herpes antibodies, whether you’ve had symptoms or not.
How Common Is It?
Very. The CDC estimates that more than 80% of people with HSV-2 don’t know they have it. That means millions of people are living with herpes and have never had a classic outbreak. The rate is even higher for HSV-1, which often goes undiagnosed when it appears as oral cold sores.
Does Asymptomatic Herpes Still Matter?
Yes—it’s still important to know your status. Even without symptoms, herpes can be transmitted to partners. It may also flare up later, especially during times of illness, stress, or immune suppression.
Knowing your status allows you to make informed decisions about safer sex, disclosure, and treatment options. For example, some people choose to take daily antiviral medication to reduce shedding and protect partners.
What If I’m Still Not Sure?
If you’ve had unprotected sex or a partner who tested positive, getting tested is the best way to find out. Even if you feel fine, a type-specific IgG blood test can detect silent infections.
