One of the most surprising things about herpes is how common it is—and how many people have it without knowing. Many individuals with herpes experience mild symptoms, no symptoms at all, or symptoms they mistake for something else. This means the virus often goes undiagnosed, sometimes for years.
Understanding how herpes can remain undetected is important for both prevention and peace of mind. Whether you’re concerned about a past exposure or simply want to know the facts, this page explains how undiagnosed herpes happens, how it spreads, and how testing can bring clarity.
Can You Have Herpes and Not Know It?
Yes. In fact, most people with herpes don’t know they have it. The CDC estimates that more than 80% of people with HSV-2 are unaware of their status. That’s because herpes symptoms can be very mild, mistaken for something else (like razor burn or a yeast infection), or not present at all.
Some people never experience noticeable outbreaks but can still carry and transmit the virus. This is known as asymptomatic shedding, and it’s one of the reasons herpes is so common despite being stigmatized and poorly understood.
Why Herpes Often Goes Undiagnosed
- Mild or no symptoms: Many people never have a classic outbreak.
- Symptoms are mistaken for something else: Herpes can resemble other conditions like ingrown hairs, jock itch, or skin irritation.
- Lack of routine screening: Herpes isn’t included in standard STD panels unless specifically requested.
- Stigma and discomfort: Some people avoid testing or ignore signs out of fear or embarrassment.
People are often surprised to learn that even sexual health clinics don’t automatically test for herpes unless there’s a specific reason to do so. This contributes to many cases going undetected—and untreated—for years.
Delays in Diagnosis Are Common
Some people first get tested years after their initial exposure. They may have had a mild symptom in the past but didn’t connect it to herpes, or assumed it was something minor. Others are told by doctors that testing isn’t necessary unless symptoms are severe, which further delays clarity.
In some cases, a person only discovers their status because a new partner gets tested and brings it up. This delayed discovery can be emotionally difficult, but it’s extremely common. Knowing your status can help you protect future partners and feel more in control of your health.
How Undiagnosed Herpes Spreads
Herpes can be transmitted even when no symptoms are present. This is called asymptomatic viral shedding, and it’s more common than many people realize. The virus can be present on the skin and passed to a partner even if there are no visible sores or discomfort.
This means you could unknowingly transmit herpes—or contract it from someone who doesn’t know they have it. That’s why testing plays such a key role in awareness and prevention.
Testing Can Offer Answers
If you’re unsure about your status, a type-specific IgG blood test can detect HSV-1 and HSV-2 antibodies. These antibodies typically develop 2 to 12 weeks after exposure and remain in the body long-term.
Lab-based testing from STDCheck or at-home kits from myLAB Box are both discreet, accurate options. Results are reviewed by licensed physicians and delivered privately online.
Testing is especially helpful if:
- You’ve had a partner test positive
- You’ve had unprotected sex with someone new
- You’ve experienced unexplained irritation or symptoms
- You simply want peace of mind about your sexual health
