How To Detect Herpes Without Symptoms

How Will My Doctor Know If I Have Herpes

Herpes (oral & genital) – causes, symptoms, diagnosis, treatment, pathology

Your healthcare provider may diagnose genital herpes by simply looking at your symptoms. Providers can also take a sample from the sore and test it. In certain situations, a blood test may be used to look for herpes antibodies. Have an honest and open talk with your health care provider and ask whether you should be tested for herpes or other STDs.

Please note: A herpes blood test can help determine if you have herpes infection. It cannot tell you who gave you the infection or how long you have been infected.

Are Test Results Accurate

Tests that identify evidence of HSV infections are routine and commonly used medical tests. The ability of a test to accurately diagnose or rule out HSV infection depends on the test used for analysis and the stage of a patients infection.

The Tzanck smear and viral culture are less able to accurately identify patients who have an HSV infection than other tests. PCR testing and antibody testing are more sensitive, which means that they miss fewer cases of infection.

Blood tests that detect antibodies to HSV can distinguish between HSV-1 and HSV-2 but not the site of infection. This means that blood tests cannot tell whether a patient has a genital or oral herpes infection.

Although these tests are valuable for identifying HSV infection, no test is perfect. When learning of test results, patients should talk to their doctor about the type of test conducted, the reliability of test results, and if additional tests are necessary to confirm or rule out a diagnosis.

Signs And Symptoms Of Herpes

Oral herpes is an infection in the mouth, caused by HSV-1 . Symptoms often include cold sores or fever blisters, but you can have oral herpes without any symptoms.

The herpes simplex virus can be dormant until an active outbreak occurs. The initial infection typically has the worst symptoms, ranging from flu-like symptoms and swollen lymph nodes to headaches. Sores may occur in and around the lips and mouth. Recurring infections are usually milder, and may include redness, itching, or swelling. Painful, fluid-filled blisters can occur and are highly contagious. These blisters often turn into sores , which will then scab over and typically heal in a few days.

Symptoms of genital herpes range from none to more severe manifestations . The majority of genital HSV infections are mild, with little to no symptoms following the initial outbreak. For people who do experience symptoms, the usual course begins with genital inflammation, where the skin may itch or burn. Blister-like sores may appear. The sores may open, scab over, and heal.

Other indirect symptoms that can occur during an active herpes virus infection include fever, headaches, muscle aches, and a burning sensation during urination.

If you think you may have a herpes infection, home testing could be a convenient option for you. If youâre wondering how to get tested for herpes at home, thereâs good news: testing for HSV-2 is easy with the Everlywell female STD Test or male STD Test.

Ways To Limit Exposure

There are sexually active couples out there who have managed for years to prevent the spread of the disease from one partner to the other. It takes care and attention to detail, but it is definitely possible.

First, try to avoid having sex when there are any blisters or sores present. Having sex during an outbreak is the easiest way to give someone herpes.

Beyond safe sex practices, for those with recognizable symptoms, not spreading the virus hinges on knowing when a flare-up is occurring even before any cold sores show up. Most often, that means looking out for a âtinglingâ sensation in and around the infected area. Sometimes, the skin has a mild burning feeling, and muscles nearby may feel like theyâre âasleep.â

For those without recognizable, symptoms, itâs a question of being tested. If youâre sexually active, and especially if you find out any past partner is infected, get tested for herpes, either by your doctor or at a clinic. For asymptomatic carriers, being aware of your condition and using a condom absolutely every time you have sex can dramatically reduce the chances of infecting someone else.

Is There A Cure For Herpes Simplex

There is no cure for herpes simplex. Once you have the virus, its a lifelong infection.

What is the outlook for people with herpes simplex?

For many people, the first herpes outbreak is the most severe. Many outbreaks are less frequent and milder after the first year of infection. Some people may have only one outbreak and never have another again.

Herpes infection doesnt usually pose a serious health risk. The risk of a health complication due to herpes is higher in infants and if you have HIV/AIDS, cancer or an organ transplant.

How Does Herpes Simplex Spread

Herpes spreads through close contact with a person who has the infection. The virus can be found in skin and saliva. If you have herpes simplex, you are most likely to pass the virus to another person when you have sores. But you can infect someone else even if you have no symptoms. Healthcare providers call this asymptomatic viral shedding.

People may get HSV-1 through

Touching a persons skin near the mouth.
Sharing food utensils, lip balm or razors.
If you receive oral sex from someone who has a cold sore, it may spread a herpes infection to your genitals.

People may get HSV-2 through

Oral sex with someone whos infected.
Skin-to-skin contact without ejaculation.
Touching open sores, including while breastfeeding.
Childbirth by a mother or gestational parent who has an active infection.

You cant get genital herpes from objects like toilet seats. But you could pass genital herpes through shared sex toys.

Why Doctors Dont Automatically Test You For Herpes

OK, clearly herpes is super common. So why dont doctors automatically test for it when you ask to get tested for everything? To answer that question, its important to understand the difference between STI testing and STI screening. Testing is done when you have symptoms, whereas screening is done in the absence of symptomsjust to check to see if youve been exposed.

Doctors will screen for STIs such as gonorrhea and chlamydia even in the absence of symptoms. This is key from a public health perspective because catching these infections in time can prevent serious complications such as pelvic inflammatory disease. This happens when an untreated STI like gonorrhea or chlamydia infects reproductive organs, possibly leading to infertility.

Experts dont screen for herpes for a few reasons.

The U.S. Preventative Task Force has recommended against screening asymptomatic adolescents and adults for HSV infections. The rationale is that there is no health benefit thats been proven and there a couple of risks, Dr. Johnston says. One is a false positive test, and the second is a risk of anxiety is not associated with serious health outcomes, yet its still feared.

Even pregnant people who could theoretically risk passing the virus during childbirth are not screened unless they have a history of herpes outbreaks or a current outbreak, Peter Leone, M.D., of UNCs Institute of Global Health and Infectious Diseases, tells SELF.

How Long Do Herpes Test Results Take

As soon as you have collected the fluid sample and sent it to the lab, it can take just 2 to 3 days after the sample has reached the lab for the results to be ready.

How Long Do Sores From Herpes Simplex Last

If youre infected with HSV-1, commonly known as oral herpes, you may notice tingling or burning around your mouth in the days before a cold sore appears. These blisters break open and ooze fluid before forming a crust. Usually, sores last for seven to 10 days.

If youre infected with HSV-2, commonly known as genital herpes, your first outbreak may last between two to four weeks. Recurrent outbreaks usually last between three to seven days.

What Are The Signs And Symptoms Of Genital Herpes

Genital Herpes: Causes, symptoms and prevention of this ailment ...

Most people infected with HSV-2 are not aware of their infection. However, the signs and symptoms of herpes during an initial outbreak can be quite pronounced. The first outbreak usually occurs within two weeks after the virus is transmitted, but the sores will also typically heal within two-to-four weeks. Other signs and symptoms during the primary episode may include a second crop of sores, and flu-like symptoms, such as fever and swollen glands. However, most individuals with HSV-2 infection never have sores, or they have very mild signs that they do not even notice or that they mistake for insect bites or other skin conditions like ingrown hairs or acne.

People who have one genital herpes outbreak can expect to have several more within a year. Over time, these outbreaks usually decrease in frequency. It is possible for a person to only become aware of the first episode years after the infection is acquired.

Genital Herpes Is Common Shouldnt Cdc Recommend Testing For Everyone

CDC recommends herpes testing for people who have genital symptoms to confirm if they have it. Testing allows a healthcare provider to talk with patients about what to expect in the future. This includes talking about medications that help with symptoms. Providers can also tell patients how to lower the risk of transmitting herpes to sex partner.

CDC does not recommend herpes testing for people without symptoms in most situations. This is because of the limits of a herpes blood test and the possibility of a wrong test result. The chances of wrong test results are higher for people who are at low risk of infection.

Blood tests might be useful if:

You have genital symptoms that could be related to herpes, or
You have a sex partner with genital herpes, or
Your provider found signs of herpes, but you still need a test to confirm it.

If you are sexually active, talk openly and honestly with your healthcare provider about what tests are right for you. These tips can help.

How Do Healthcare Providers Test For Herpes

How are you tested for herpes at a clinic or healthcare providerâs office? Healthcare providers will examine the location and severity of any active blisters or sores around the mouth or genital area. They may take a tissue sample of the sores to send to a laboratory for examination. A blood sample will be needed if an antibody test is used to check whether you have been infected with the herpes virus.

Testing With No Symptoms

Herpes Spreads, Even Without Symptoms

Blood tests can be used when a person has no visible symptoms but has concerns about having herpes. Blood tests do not actually detect the virus instead, they look for antibodies in the blood.

IgM vs. IgG

When an individual contracts herpes, the immune system responds by developing antibodies to fight the virus: IgG and IgM. Blood tests can look for and detect these antibodiesnot the virus itself. IgG appears soon after infection and stays in the blood for life. IgM is actually the first antibody that appears after infection, but it may disappear thereafter.

IgM tests are not recommended because of three serious problems:

The accurate herpes blood tests detect IgG antibodies. Unlike IgM, IgG antibodies can be accurately broken down to either HSV-1 or HSV-2. The challenge here is that the time it takes for IgG antibodies to reach detectable levels can vary from person to person. For one person, it could take just a few weeks, while it could take a few months for another. So even with the accurate tests, a person could receive a false negative if the test is taken too soon after contracting the virus.

For the most accurate test result, it is recommended to wait 12 16 weeks from the last possible date of exposure before getting an accurate, type-specific blood test in order to allow enough time for antibodies to reach detectable levels.

Doctors Don’t Advise Getting A Blood Test For Herpes Without Any Symptoms

Hilda Hutcherson, assistant professor of obstetrics and gynecology at Columbia University Medical Center in New York, is one of those doctors. “I usually dont do tests for herpes someone has a lesion or a sore, something I can see, I will do a swab and take it to a culture or check the DNA on the materials I removed,” she says. “If theres nothing there and I do a blood test and the blood test comes back positive, lets say its positive for type 1, what does that really mean? Most people are positive for type 1.” She adds that someone could be HSV-1-positive and either have or not have genital herpes. The result “doesnt mean much, and it makes people go crazy.”

Hutcherson’s motto is pretty simple: Why stress yourself over something if you haven’t seen anything especially when it’s something as common as herpes? “Let’s say they have a blood test come in positive but theyve never had a lesion. Now what? You may never get a lesion,” she says. It’s for this reason that she recommends people do not get tested for herpes unless they have a visible lesion that can be cultured and sent to a lab. Let’s say you get tested anyway and it comes back positive, despite the fact that you have no symptoms. What do you do?

What Does The Test Result Mean

Direct detection of the virus

A positive HSV DNA test or culture indicates that you have an active herpes infection, and the result may indicate if it is HSV-1 or HSV-2.
A negative PCR test or culture indicates that the herpes simplex virus was not detected, but this does not definitely rule out an infection. False negatives can occur if there is not enough active virus in the sample. This may happen if the lesion is cultured more than 48 hours after the symptoms appear. If suspicion of herpes remains high, repeat testing may be done.

Antibody blood tests

A positive HSV-1 or HSV-2 IgG antibody test means antibodies are present in your blood, which means you have had an infection in the past even if you haven’t noticed any symptoms. The type of antibody detected indicates the type of HSV infection.
Negative HSV antibody results mean that it is unlikely that you have been exposed to HSV or it may mean that your body has not had time to begin producing HSV antibodies.

What Happens During An Hsv Test

HSV testing is usually done as a swab test, blood test, or lumbar puncture. The type of test you get will depend on your symptoms and health history.

For a swab test, a health care provider will use a swab to collect fluid and cells from a herpes sore.
For a blood test, a health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.
A lumbar puncture, also called a spinal tap, is only done if your provider thinks you may have an infection of the brain or spinal cord. During a spinal tap:
You will lie on your side or sit on an exam table.
A health care provider will clean your back and inject an anesthetic into your skin, so you wont feel pain during the procedure. Your provider may put a numbing cream on your back before this injection.
Once the area on your back is completely numb, your provider will insert a thin, hollow needle between two vertebrae in your lower spine. Vertebrae are the small backbones that make up your spine.
Your provider will withdraw a small amount of cerebrospinal fluid for testing. This will take about five minutes.
Your provider may ask you to lie on your back for an hour or two after the procedure. This may prevent you from getting a headache afterward.
