Key takeaways:
Genital herpes is a common sexually transmitted infection (STI) that leads to genital irritation and sores.
Many cases of genital herpes can be mild, and some people may not even realize they have it.
Someone can pass genital herpes even without symptoms. It’s important for people who are sexually active to get regular testing to know if they have the virus.
Genital herpes is a sexually transmitted infection (STI) that’s much more common than most people realize. About 1 in 6 people in the U.S. have genital herpes, although the actual number is likely higher since many people don’t know they have it.
Genital herpes is caused by a virus (herpes simplex virus, or HSV) that lives in the body forever. And it can easily spread from person to person during oral, genital, or anal sex — even when a person doesn’t have active symptoms.
Let’s take a closer look at eight common symptoms of genital herpes so you know what to look for and when to get tested.
A fever is your body’s response to a boost in the immune system to handle viruses like herpes. At the same time, chills can happen as your body tries to control its temperature during a fever.
STD testing: Not sure how often to be tested for sexually transmitted diseases (STDs) or infections (STIs)? This guide to STIs can help you know what to be tested for and when.
Oral herpes: Find out what tongue herpes looks like and how to manage the pain.
Private STD testing: You can get some STD testing done at home. Find out which infections can be tested privately, without visiting a clinic.
When your body fights a virus like genital herpes, it can cause flu-like symptoms. And headaches are common.
Fatigue is a common symptom of genital herpes as your body’s defenses kick into action. It’s more often seen as a symptom of your first outbreak, and not so much with recurrent flares. You can often feel tired because your body is putting a lot of energy into fighting the virus.
The immune response to the herpes virus can cause inflammation and irritation. This occurs not only in the genital area but also throughout the body. And this can leave your body and muscles feeling achy. Again, you’re more likely to see this with your initial infection.
One of the most well-known signs of genital herpes is having sores or lesions on the genitals. These sores can be painful and look different for each person. They can include:
Blisters
Pimples
Open sores
Scabbing lesions
Swollen lymph nodes in the genital area are common with a herpes infection. These are normally pea-sized glands located throughout the body to help you fight infection. The glands in the groin might get bigger and sore during a genital herpes outbreak.
Before the sores appear, there can be tingling or itching in the private area or around the bottom. This can also sometimes feel like a burning sensation. This can be a sign that a herpes outbreak is about to happen.
Discomfort when you urinate can be a sign of a genital herpes infection. While herpes doesn’t directly impact the urinary tract, the open sores can become irritated and hurt when urine touches them.
The first or primary outbreak of genital herpes tends to be the most severe. Usually, a red patch of skin shows up with tiny bumps that feel a bit raised. These bumps turn into clear, fluid-filled bumps called “vesicles.” Later, the bumps break open and become painful sores.
As the sores heal, they form scabs. It usually takes about 2 weeks for the scabs to go away, but sometimes it can take up to 6 weeks. During this time, you might feel itchy or uncomfortable. You may also notice some systemic symptoms like fever, chills, or fatigue.
Taking good care of the sores and getting treatment can help them go away faster. But it’s important to know that herpes sores can come back again and again over time. Future outbreaks may be milder. They can have fewer sores, less severe symptoms, and happen less often.
Herpes symptoms can start to appear anywhere from a few days to a few weeks after being exposed to the virus. The timing of when your symptoms start can vary widely.
You should get medical advice promptly if you may have been exposed to herpes or have symptoms. A healthcare professional can do tests to confirm the virus. They can also provide guidance on managing symptoms and preventing transmission.
Finding and treating herpes early is crucial. It reduces the risk of complications and improves quality of life.
It’s possible to have genital herpes and not know it. That’s because not everyone with genital herpes experiences noticeable symptoms. Mild cases often go unnoticed. And a single sore can be confused with an ingrown hair, razor burn, or even just minor irritation.
There are two types of herpes: herpes simplex virus 1 (HSV-1) and herpes simplex virus 2 (HSV-2). HSV-2 more commonly causes genital herpes. HSV-1 usually causes oral herpes, but some cases of genital herpes are due to HSV-1. This may be the case if the virus is transmitted from the mouth to the genitals during oral sex. Both types may cause no symptoms or only mild symptoms.
If you think that you may have been exposed or infected, it’s important to know what to look out for. By knowing the signs and symptoms, you may be able to prevent transmission.
It’s important to keep in mind that it’s still possible for someone to pass the virus to their partner(s) even if they don’t have any sores. Although active sores do increase the risk of transmitting the infection.
There are several STIs that can cause bumps and sores that look a lot like genital herpes. But there are some helpful clues that may help you and your healthcare professional tell the difference:
Syphilis sores: These sores aren’t painful, unlike herpes, which tends to cause some discomfort.
Chancroid ulcers: These often appear more gray or yellow. And the fluid inside the bumps appears white rather than clear.
Lymphogranuloma venereum: This generally causes small bumps, but not fluid-filled bumps or ulcers like herpes.
Granuloma inguinale ulcers: These are painless and tend to have a red, beefy appearance. They may bleed easily.
Genital herpes can also be mistaken for other, nonsexually transmitted conditions. This is especially true if someone doesn’t have the hallmark sores. Some common examples include:
Ingrown hairs, razor bumps, or pimples
Hemorrhoids (when the sores are around the anus)
Urinary tract infection (UTI)
Yeast infection — especially in women
Vaginitis — a condition that leads to inflammation of the vagina
The good news is that when the diagnosis is unclear, there are some simple tests that can help.
If you’re worried that you may have genital herpes, don’t hesitate to reach out to your primary care provider to schedule an appointment. If you have active sores, many healthcare professionals can confidently diagnose you with genital herpes based on appearance. But laboratory testing to confirm herpes infection is also available and recommended.
If you do have active sores, a healthcare professional may swab the area and look at the sample under the microscope. They may also send the sample to a lab to test for the presence of HSV-1 and HSV-2.
Your primary care provider can also take a blood test if you don’t have active sores, but you’re worried about exposure. This can be helpful because it doesn’t need to be timed with an outbreak.
Blood tests can have a few drawbacks, though:
Some blood tests can’t differentiate between HSV-1 and HSV-2.
If it’s positive, it doesn’t specify how long you’ve had the infection.
It isn’t always positive right after you get the infection. So this may mean you need to schedule a repeat test.
Talk with a healthcare professional about the type of blood test that may be best for you. They can provide useful information, and you can do it at any time — even with no symptoms.
Genital herpes can be a scary diagnosis for people who are sexually active. But it’s much more common than people realize. There are some common symptoms of herpes infection, but it’s possible to have the infection and not know it. If you’re sexually active, it’s always a good idea to get tested for a herpes infection and other STIs.
