The herpes simplex virus is incredibly common in the United States and worldwide.

As many as 1 in 2 American adults have oral herpes, which is often caused by herpes simplex virus type 1 (HSV-1).Herpes fast facts. (n.d.).ashasexualhealth.org/stdsstis/herpes/fast-facts-and-faqs/

An estimated 1 in 8 Americans ages 14 to 49 years old have genital herpes from herpes simplex virus type 2 (HSV-2), which causes most cases of genital herpes.Herpes fast facts. (n.d.).ashasexualhealth.org/stdsstis/herpes/fast-facts-and-faqs/

However, either type of HSV can occur in the genital or oral region. An infection with both HSV types at the same time is also possible.

Although some people carry the virus and never experience any symptoms, others may have frequent outbreaks.

This article will examine why so many people carry the virus, how to prevent transmission, and more.

How is this possible?

Most HSV infections are asymptomatic, so many people who carry the virus don’t know that they have it.

What’s more, the virus is easily transmitted.

In many cases, all it takes is:

a kiss

oral sex

genital-to-genital contact

HSV-1

According to the New York State Department of Health, most people are first exposed to HSV-1 before the age of 5 years old.Herpes simplex virus in the newborn. (2011).health.ny.gov/diseases/communicable/herpes/newborns/fact_sheet.htm

In these cases, oral herpes is likely the result of close contact with a parent or sibling.

For example, a parent who has HSV-1 can transmit the virus to their child if they kiss them on the mouth or share straws, eating utensils, or any other objects that have the virus on them.

A person who has HSV-1 can transmit the virus regardless of whether they’ve ever had cold sores or have an active cold sore outbreak.

HSV-2

HSV-2 infections that cause genital herpes are usually transmitted through sexual contact.

This includes contact with the genitals, semen, vaginal fluid, or skin sores of a person who has HSV-2.

As with HSV-1, HSV-2 can be transmitted regardless of whether it’s causing sores or other noticeable symptoms.

More females than males contract genital herpes as a result of HSV-2.Herpes simplex virus. (2017).who.int/news-room/fact-sheets/detail/herpes-simplex-virus

This is because a genital herpes infection is easier to transmit from a penis to a vagina than it is from a vagina to a penis.

What’s the difference between oral and genital herpes?

It’s an oversimplification to say that HSV-1 causes oral herpes and HSV-2 causes genital herpes, though these are the easiest definitions of each.

HSV-1 is a subtype of the herpes virus that typically causes oral herpes. This is also known as cold sores.

HSV-1 can also cause genital blisters that appear very similar to the genital blisters associated with HSV-2 virus.

Any herpes sore or blister — regardless of its subtype — can burn, itch, or tingle.

The HSV-2 subtype of the herpes virus causes genital sores, as well as swollen lymph nodes, body aches, and fever.

Although HSV-2 can also cause sores on the face, it’s much less common than genital sores.

It’s difficult to look at a herpes sore and determine whether it was caused by HSV-1 or HSV-2.

To make a diagnosis, a doctor or other healthcare provider would have to take a sample of fluid from a blister lesion or take a small sample of the skin lesion and send it to a lab for testing.

There’s also a blood test available.

So cold sores are only caused by HSV-1?

Both HSV-1 and HSV-2 can cause cold sores on the mouth and face.

Although it’s more common for HSV-1 to cause cold sores, it isn’t impossible for HSV-2 to cause them, too.

Are cold sores the same thing as canker sores?

Cold sores aren’t the same thing as canker sores or mouth ulcers. They each have different causes and two entirely different presentations.

Cold sores:

are caused by the herpes simplex virus

usually develop near the outside of the mouth, such as below your nostrils or on your lips

cause redness and fluid-filled blisters

usually appear in groups

usually burn or tingle

eventually break and ooze, forming a crust-like scab

may take 2 to 4 weeks to completely heal

Canker sores:

may be caused by food or chemical sensitivities, dietary deficiencies, minor injury, or stress

may develop anywhere inside your mouth, such as at the base of your gum line, inside your lip, or under your tongue

are shaped like a circle or oval

are typically yellow or white with a red border

may appear solo or in groups

usually take 1 to 2 weeks to completely heal

Are HSV-1 and HSV-2 spread the same way?

HSV-1 is spread through direct contact with the virus, which can be present in or around cold sores, in oral secretions (like saliva), and in genital secretions (like semen).

Some of the ways it can be transmitted include:

kissing someone on the mouth

sharing eating utensils or cups

sharing lip balm

performing oral sex

The herpes virus usually affects the area where it first made contact with the body.

So if a person who has HSV-1 performs oral sex on their partner, HSV-1 could be transmitted to their partner who could then develop genital sores.

HSV-2, on the other hand, is usually only transmitted through sexual contact. This includes genital-to-genital contact and contact with genital secretions such as semen.

Some of the ways HSV-2 can be transmitted include:

oral sex

vaginal sex

anal sex

How long does it take after exposure to register in your system?

When a person is exposed to the herpes virus, the virus travels through the body to nerve cells near the spinal cord known as a dorsal root ganglion.

For some people, the virus stays there latent and never causes any symptoms or problems.

For others, the virus will express itself and activate periodically, causing sores. This doesn’t always happen immediately after exposure.

Doctors don’t know exactly why some people get mouth or genital sores and others don’t, or why the virus decides to activate.

Doctors do know that sores are more likely to develop in the following circumstances:

in times of severe stress

after exposure to cold weather or sunlight

after tooth extractions

alongside hormone fluctuations, such as pregnancy or menstruation

if you have a fever

if other infections are present

Sometimes, a person can identify the triggers that cause them to have a herpes outbreak. Other times, the triggers are seemingly random.

Why isn’t HSV included in routine STI screenings or other lab work?

Major health organizations like the Centers for Disease Control and Prevention (CDC) don’t recommend screening someone for herpes unless symptoms are present.Genital herpes screening FAQ. (2017).cdc.gov/std/herpes/screening.htm

According to the CDC, there isn’t any evidence that diagnosing the condition when symptoms aren’t present leads to a change in sexual behavior.Genital herpes screening FAQ. (2017).cdc.gov/std/herpes/screening.htm

Although an asymptomatic diagnosis doesn’t have physical impact, it can still have a negative effect on mental health.

In many cases, the associated stigma may be more troubling than the actual diagnosis.

It’s also possible that a person who is asymptomatic could receive a false positive, resulting in needless emotional turmoil.

How will you know if you have HSV?

In most cases, you won’t know unless you develop blisters or sores on the mouth or genitals. These sores usually have a burning, tingling sensation.

If you think you’ve been exposed to HSV-2 or would like to know if you carry the virus, talk to a doctor or other healthcare provider about testing.

Can you still have sex if you have HSV?

Yes, you can still have sex if you have HSV-1 or HSV-2.

However, you should avoid intimate contact if you’re experiencing an active outbreak. This will reduce the risk for transmission to your partner.

For example, if you have a cold sore you should avoid kissing your partner or performing oral sex.

If you have an active genital outbreak, you should avoid any below-the-belt activity until it clears.

Although the virus is less likely to spread when no symptoms are present, practicing sex with a condom or another barrier method, such as a dental dam, can help reduce the overall risk for transmission.

Is there anything else you can do to prevent transmission?

You may also consider talking to your healthcare provider about prescription antiviral medication, such as:

acyclovir (Zovirax)

famciclovir (Famvir)

valacyclovir (Valtrex)

These medications can help suppress the virus and reduce the risk of transmission.

In rare cases, herpes can be transmitted during pregnancy or childbirth.Reassurances about genital herpes during pregnancy and birth. (n.d.). herpes.org.nz/patient-info/herpes-pregnancy/

If you’re pregnant, or planning to become pregnant, talk to an obstetrician or other healthcare provider about the steps you can take to reduce the risk for transmission.

Is there a cure for HSV-1 or HSV-2?

There’s currently no cure for HSV-1 or HSV-2. The antiviral therapy for HSV suppresses the viral activity, but it doesn’t kill the virus.

The CDC notes that any potential vaccines are being tested in clinical trials.Genital herpes — CDC fact sheet. (2017).cdc.gov/std/herpes/stdfact-herpes.htm Otherwise, vaccination against HSV isn’t commercially available.

If you contract HSV, the goal is to keep your immune system functioning at a high level to help prevent active outbreaks from occurring.

Antiviral therapy may also help to prevent or shorten outbreaks from occurring.

Are these the only herpes viruses?

There are actually several other subtypes of herpes viruses that are from the same family as HSV-1 and HSV-2. This family is known as Herpesviridae.

Alternatively, HSV-1 and HSV-2 are also known as human herpesvirus 1 (HHV-1) and human herpesvirus 2 (HHV-2), respectively.

The other human herpesviruses include:

Human herpesvirus 3 (HHV-3): Also known as the varicella zoster virus, this virus causes chickenpox lesions.

Human herpesvirus 4 (HHV-4): Also known as the Epstein-Barr virus, this virus causes infectious mononucleosis.

Human herpesvirus 5 (HHV-5): Also known as the cytomegalovirus, this virus causes symptoms such as fatigue and muscle aches.

Human herpesvirus 6 (HHV-6): This virus can cause a serious illness in infants known as “sixth disease,” which is also called roseola infantum. The virus causes a high fever and distinctive rash.

Human herpesvirus 7 (HHV-7): This virus is similar to HHV-6 and can cause some cases of roseola.

Human herpesvirus 8 (HHV-8): This virus can contribute to a serious illness known as Kaposi sarcoma, which can lead to connective tissue cancer.

Many of these subtypes (such as HHV-3) are contracted in childhood.

The bottom line

If you recently received a diagnosis, know that you’re not alone. Most adults carry at least one form of herpes virus, if not more.

You may also find comfort in knowing that when symptoms are present, the first outbreak is generally the most severe.

Once the initial outbreak clears, you may not experience another flare-up for many months, if at all.

If you have questions about treatment, see a healthcare provider. They can advise you on any next steps.
