After the initial infection, the herpes simplex virus (HSV) doesn’t leave your body. Instead, it enters a phase called “latency” or dormancy, where it hides in your nerve cells without causing symptoms. This is one of the defining features of both HSV-1 and HSV-2—and it’s why herpes can feel unpredictable and confusing.
During dormancy, the virus isn’t gone—it’s just inactive. It can reactivate at any time, leading to outbreaks or asymptomatic shedding (which still carries a risk of transmission). Understanding how dormant herpes works is key to managing symptoms, minimizing risk to partners, and living confidently with the virus.
How Long Can Herpes Stay Dormant?
There’s no set timeline. For some people, the virus reactivates frequently—especially during the first year. For others, it may stay dormant for months, years, or even permanently. Common triggers for reactivation include:
- Stress or fatigue
- Illness or fever
- Hormonal changes (e.g., menstruation)
- Friction or irritation from sex or clothing
It’s even possible to carry the virus for decades without ever experiencing noticeable symptoms. This is sometimes referred to as “unrecognized” or “asymptomatic” herpes.
Can You Spread Herpes If It’s Dormant?
Yes. Even when there are no visible sores, the virus can still shed from the skin—especially in the genital or oral area. This is called asymptomatic shedding, and it’s one of the most common ways herpes is transmitted.

Is Dormant Herpes Curable?
No—once the virus enters your nervous system, it can’t be removed. However, antiviral medications can help suppress the virus, reducing the frequency of outbreaks and the likelihood of shedding.

What Happens in the Body During Latency?
When dormant, the virus lives in clusters of nerve cells called ganglia. For genital herpes, it typically resides in the sacral ganglia at the base of the spine. For oral herpes, it hides in the trigeminal ganglia near the base of the skull. It can stay inactive here indefinitely, only reactivating in response to specific triggers.
How Do You Know If the Virus Is Reactivating?
One of the earliest signs that herpes may be coming out of dormancy is a tingling or burning sensation near the site of the initial outbreak. This is known as the “prodrome” stage. It often occurs a day or two before visible sores appear, giving people an opportunity to start antiviral medication early and possibly prevent a full outbreak.
Other reactivation clues may include mild itching, nerve discomfort, or flu-like symptoms. Over time, many people become familiar with their own warning signs and learn how to respond proactively.
Can Dormant Herpes Become Active Without Symptoms?
Yes. Even without a visible outbreak, the virus can still reactivate in a process called subclinical reactivation. During these periods, the virus may travel to the skin’s surface and shed, increasing the risk of transmission without causing any discomfort or noticeable signs.
This is one reason why herpes spreads so easily. Using protection and suppressive antiviral therapy can help lower the odds of shedding and passing the virus to others, even if you feel completely fine.

Frequently Asked Questions
Can herpes lay dormant for years?
Yes. Many people carry HSV-1 or HSV-2 for years without symptoms. The virus can stay hidden in the body indefinitely, reactivating only in response to certain triggers—or never at all.
Can you test positive if the virus is dormant?
Yes. Blood tests for herpes detect antibodies, not active virus. So even if the virus is dormant, your immune system’s response will show up on a test.
Is dormant herpes contagious?
It can be. Asymptomatic shedding may still occur even when you’re not experiencing symptoms. Suppressive antiviral therapy can help reduce this risk.
