Herpes FAQs

What is Herpes?

Herpes is a common viral infection caused by the herpes simplex virus (HSV).

There are two types: HSV-1 and HSV-2.

Both can cause infections in various body parts, including the mouth, lips, nose, eyes, and genitals.
Herpes is characterized by recurring outbreaks of painful sores or blisters.

The virus remains in your body for life and can be managed but not cured.
Herpes is a global issue, with over half a billion people worldwide estimated to have genital herpes and several billion with oral herpes.
While herpes is uncomfortable, it doesn't lead to serious health problems in healthy adults.

However, it can be dangerous for people with weakened immune systems and for newborns.

What are the two types of herpes?

HSV-1 primarily causes oral herpes, which results in cold sores and fever blisters around the mouth and face.

HSV-2 primarily causes genital herpes and is commonly transmitted through sexual activity.
Both HSV-1 and HSV-2 can cause sores in either the oral or genital area.

The type of herpes is determined by the infection location, not the virus type.
It's important to note that both types transmit even without visible sores or symptoms.

This is called asymptomatic shedding.
While both types cause similar symptoms, they're generally associated with different health issues.

HSV-1 is often linked to oral health issues, while HSV-2 is more often associated with genital health issues.

How to know if I have herpes?

Herpes symptoms vary greatly.

Some people experience blister or sore outbreaks, while others have no noticeable symptoms.

The best way to know if you have herpes is to get tested by a healthcare provider.
Common herpes symptoms include blisters or sores at the infection site, flu-like symptoms such as fever and swollen lymph nodes, and tingling or itching at the infection site before an outbreak.
It's important to note that herpes can be asymptomatic, meaning you can have the virus and transmit it to others without showing any symptoms.

This is why testing is crucial if you believe you may have been exposed.
Several test types are available for herpes, including viral culture tests, PCR tests, and blood tests.

Your healthcare provider can help determine which test is best for you.

What are cold sores?

Cold sores, also known as fever blisters, are small blisters that form on the lips or around the mouth.

They're caused by the herpes simplex virus, specifically HSV-1.

Cold sores are contagious and spread from person to person through close contact like kissing.
Cold sores typically begin with a tingling, itching, or burning sensation around the mouth.

After a few days, small fluid-filled sores appear.

These sores eventually burst and crust over, forming a scab that heals without leaving a scar.
Outbreaks can be triggered by various factors, including stress, fatigue, sunlight, hormonal changes, and a weakened immune system.
While there's no cure for cold sores, treatments help reduce severity and frequency of outbreaks and lower transmission risk to others.

What are the differences between oral and genital herpes?

Oral herpes is usually caused by HSV-1 and results in cold sores or fever blisters on or around the mouth.

Genital herpes, usually caused by HSV-2, results in sores on or around the genitals.

Both types can transmit to either the oral or genital area of a partner.
Oral herpes is most commonly transmitted through direct contact with the saliva or sores of an infected person, typically through kissing.

Genital herpes is most commonly transmitted through sexual contact.
Both types cause painful sore outbreaks, but outbreak frequency and severity vary greatly from person to person.

Some may have frequent outbreaks, while others have only occasional ones or none at all.
While both types are uncomfortable, they typically don't lead to serious health problems.

However, genital herpes can increase your risk of contracting other sexually transmitted infections, including HIV.

How is herpes transmitted?

Herpes transmits through direct skin-to-skin contact, such as kissing or sexual contact.

The virus can spread even when the infected person has no symptoms.
Herpes spreads in several ways.

Oral herpes is most commonly transmitted through direct contact with the saliva or sores of an infected person, typically through kissing.

Genital herpes is most commonly transmitted through sexual contact.
It's also possible for a pregnant woman with genital herpes to transmit the virus to her baby during childbirth, which can lead to serious health problems for the baby.
While condoms can reduce genital herpes transmission risk, they don't provide complete protection because the virus can infect areas not covered by a condom.

How do I get tested for herpes?

If you suspect you have herpes, see a healthcare provider.

They can swab a sore and test it.

Blood tests can also look for antibodies to the virus.
Several herpes test types are available, including viral culture tests, PCR tests, and blood tests.

Viral culture and PCR tests involve swabbing a sore and testing it for the virus.

Blood tests look for antibodies in your blood, indicating past or current infection.
It's important to note that herpes testing isn't typically included in standard STI testing panels, so you may need to request it specifically.

Also, since it takes several weeks for your body to produce antibodies, testing too soon after exposure may not provide accurate results.
If you test positive for herpes, your healthcare provider can provide information and resources to help manage the condition, including antiviral medications to control outbreaks and reduce transmission risk.

Is there a cure for herpes?

There's currently no cure for herpes.

However, medications help manage symptoms, reduce outbreak frequency, and lower transmission risk.
Antiviral medications like acyclovir, famciclovir, and valacyclovir are the most common herpes treatments.

These medications reduce outbreak severity and duration, prevent outbreaks from occurring, and lower transmission risk.
In addition to medication, lifestyle changes help manage herpes.

This includes eating a healthy diet, getting regular exercise, getting enough sleep, and managing stress.

Avoiding outbreak triggers like sunlight and stress also helps manage the condition.
While there's no cure, it's important to remember that herpes can be managed and that people with herpes can lead healthy, active lives.

How can I prevent herpes outbreaks or cold sores?

Manage and prevent outbreaks by taking antiviral medications, maintaining a healthy lifestyle, reducing stress, and using sun protection.

A diet high in lysine and low in arginine also helps prevent and reduce herpes severity.
Lysine is an amino acid that interferes with herpes virus replication, helping prevent outbreaks.

Foods high in lysine include fish, chicken, beef, lamb, milk, cheese, beans, brewer's yeast, mung bean sprouts, and most fruits and vegetables.
Arginine, on the other hand, can trigger outbreaks.

Foods high in arginine include nuts and seeds, red meat, eggs, and grains.
It's also important to maintain a strong immune system, as a weakened one can trigger outbreaks.

This is achieved through a healthy lysine-rich diet, regular exercise, adequate sleep, and stress management.

Regular healthcare provider check-ups also help monitor your condition and adjust treatment as needed.
Finally, remember that while these strategies help manage herpes and prevent outbreaks, they don't substitute for medical treatment.

Always consult with a healthcare provider for advice tailored to your specific circumstances.
