Herpes is one of the most common viral infections worldwide, caused by the herpes simplex virus (HSV). There are two main types: HSV-1, which is primarily associated with oral herpes, and HSV-2, which typically causes genital herpes. However, both types can affect either region depending on the type of contact. Understanding how symptoms show up—and how they vary between HSV-1 and HSV-2—is the first step toward getting tested, staying informed, and protecting both your health and your partners.

Despite its prevalence, herpes remains widely misunderstood. Many people believe they would “know” if they had it, but in reality, the majority of infections are either mild or entirely asymptomatic. In the United States alone, it’s estimated that more than 1 in 6 people aged 14 to 49 have genital herpes, but up to 90% don’t realize they’re infected.

What Are the Common Symptoms of Herpes?

Herpes symptoms can range from obvious and painful to subtle or unnoticeable. For many people, the first outbreak is the most severe, with recurrent outbreaks becoming milder over time. The following symptoms can appear with either HSV-1 or HSV-2:

  • Tingling, burning, or itching near the mouth, genitals, or anus
  • Small red bumps or blisters that break open and crust over
  • Painful urination (in genital herpes cases)
  • Swollen lymph nodes, fatigue, headache, or flu-like symptoms
  • Discomfort during sex or irritation in the affected area

These symptoms typically last 2 to 4 weeks during an initial outbreak. But not everyone experiences these signs. Some people carry the virus for years without ever having a noticeable outbreak. This is known as an asymptomatic infection—and it’s far more common than most people think.

HSV-1 vs. HSV-2: Understanding the Differences

Although HSV-1 and HSV-2 are genetically similar viruses, the symptoms they cause can differ slightly depending on the location of infection and the individual’s immune response:

  • HSV-1: Often affects the mouth and lips (oral herpes), but increasingly causes genital herpes through oral-genital contact. Recurrences tend to be less frequent when HSV-1 infects the genital area.
  • HSV-2: Primarily causes genital herpes. It’s more likely to result in recurring outbreaks and is more efficiently transmitted through sexual contact.

While both types can cause similar lesions—fluid-filled blisters that rupture and scab—people with HSV-2 often experience more frequent symptoms in the genital region, especially in the first year after infection. After that, the body typically builds up resistance, and outbreaks become less frequent and less severe.

Why Testing Is So Important

If you’re experiencing symptoms—or if you’ve had a partner test positive—it’s important to get tested. Herpes can be diagnosed through swab tests during an active outbreak or through a blood test that checks for HSV antibodies. Each method has its pros and cons, depending on whether you’re currently symptomatic or not.

Getting tested doesn’t just provide peace of mind—it can help reduce the risk of unknowingly passing the virus to others. With the right information, people with herpes can take simple steps to reduce transmission risk, such as using antiviral medication, avoiding contact during outbreaks, and communicating openly with partners.

Frequently Asked Questions

Can I have herpes and not know it?

Yes. Most people with HSV-1 or HSV-2 don’t have noticeable symptoms, which is why the virus often spreads unknowingly. You could carry herpes for years without realizing it.

Are herpes symptoms the same for everyone?

No. Some people experience painful, recurring outbreaks, while others may only have one mild episode—or none at all. Factors like immune health, location of infection, and the virus type all play a role.

What does a herpes sore look like?

Herpes sores usually start as small blisters, which then break open and form shallow ulcers. They eventually crust over and heal. During an initial outbreak, they may be accompanied by flu-like symptoms.

Can I tell whether I have HSV-1 or HSV-2 just by symptoms?

No. While there are typical patterns, symptoms alone aren’t enough for a definitive diagnosis. A herpes test is the only reliable way to identify the type of virus you have.
