What Is Genital Herpes?

Genital herpes is a sexually transmitted infection caused by the herpes simplex virus. Either HSV-1 or HSV-2 can affect the genital area.

After the initial infection, the virus remains in the body and may reactivate. Some people experience recurring outbreaks, while others develop mild symptoms or none at all.

Current treatments can shorten outbreaks, reduce symptoms, and lower transmission risk, but they do not permanently remove the virus from the body.

Common Symptoms of Genital Herpes

Symptoms vary considerably between individuals. Possible signs include:

• Small blisters around the genitals or anus
• Painful open sores
• Tingling, itching, or burning
• Painful urination
• Genital tenderness or swelling
• Unusual vaginal or urethral discharge
• Swollen lymph nodes
• Fever, headache, or body aches
• Pain in the buttocks, thighs, or lower back
• Recurrent irritation in the same area

A first recognized outbreak may be more severe than later recurrences. However, mild herpes can resemble ingrown hairs, pimples, skin irritation, or another genital condition.

How Is Genital Herpes Transmitted?

HSV may spread through:

• Vaginal, anal, or oral sexual contact
• Direct skin-to-skin contact with an affected area
• Contact with herpes sores or genital fluids
• Viral shedding when no visible sores are present
• Oral-to-genital contact involving oral HSV-1
• Transmission during childbirth

Penetration is not required for transmission. A person can pass HSV without knowing they carry it.

HSV-1 vs. HSV-2

Both virus types can cause genital herpes.

Genital HSV-1

Genital HSV-1 is commonly associated with oral-to-genital contact. It generally causes fewer genital recurrences and less frequent asymptomatic shedding than genital HSV-2.

Genital HSV-2

HSV-2 more commonly causes recurring genital outbreaks and asymptomatic genital shedding. The clinical appearance alone cannot reliably determine the virus type.

Testing can help identify whether HSV-1 or HSV-2 is present.

Genital Herpes Diagnosis in Busan

A doctor may review:

• When symptoms began
• Appearance and location of lesions
• Previous outbreaks
• Recent sexual contact
• Condom use
• Partner symptoms or diagnosis
• Pregnancy possibility
• Previous STI test results
• Medication and allergy history

Testing may include:

• PCR testing from a fresh blister or sore
• Viral swab testing
• Type-specific HSV blood testing in selected cases
• Syphilis testing
• HIV screening
• Gonorrhea and chlamydia testing
• Testing for other causes of genital sores

Testing a fresh, active lesion generally provides the most direct evidence of genital HSV.

Herpes PCR and Swab Testing

PCR testing from an active lesion can detect HSV and usually identify whether it is HSV-1 or HSV-2.

Testing is most useful when:

• A blister or new sore is present
• The lesion has not fully healed
• The area has not been heavily treated with topical products
• The sample is collected promptly

A negative swab does not always exclude herpes, especially when the lesion is old, healing, or no longer producing enough virus for detection.

HSV Blood Testing

Type-specific antibody testing may show previous exposure to HSV-1 or HSV-2. However, it cannot reliably determine:

• When the infection occurred
• Where on the body HSV-1 is located
• Which partner transmitted it
• Whether a current genital lesion is caused by HSV

Blood testing performed too soon after exposure may also be negative. A doctor can explain whether testing or repeat testing is appropriate.

Genital Herpes Treatment Options

Antiviral Medication

Prescription antiviral medication can:

• Shorten an outbreak
• Reduce pain and discomfort
• Support faster healing
• Decrease the duration of viral shedding
• Reduce the frequency of future outbreaks
• Lower—but not eliminate—transmission risk

Treatment is most effective when started early, particularly during a first outbreak or when tingling and burning begin before recurring sores appear.

Episodic Treatment

Episodic therapy is taken when an outbreak begins. It may be appropriate for patients with occasional recurrences who can recognize early symptoms.

Patients may be provided with medication in advance so treatment can begin promptly.

Suppressive Treatment

Daily suppressive antiviral therapy may be considered for patients who:

• Experience frequent outbreaks
• Have severe or distressing recurrences
• Want to reduce transmission risk
• Have an uninfected sexual partner
• Experience significant anxiety related to outbreaks

Suppressive therapy reduces but does not completely prevent outbreaks or transmission.

Pain and Symptom Relief

Supportive care may include:

• Doctor-approved pain medication
• Loose, breathable clothing
• Keeping the area clean and dry
• Warm baths
• Avoiding friction
• Using cool compresses
• Drinking enough water

Patients should avoid applying unapproved creams, disinfectants, or home remedies to open lesions.

First Genital Herpes Outbreak

A first outbreak may involve multiple painful sores, fever, body aches, swollen lymph nodes, or difficulty urinating. Prescription antiviral therapy is generally recommended.

Patients with severe pain, widespread lesions, pregnancy, immune suppression, or urinary difficulty may require urgent specialist or hospital care.

Recurrent Genital Herpes

Recurring outbreaks are often milder and shorter. Some patients notice warning symptoms such as tingling, itching, or localized discomfort before lesions appear.

Possible triggers may include:

• Illness
• Stress
• Fatigue
• Sleep deprivation
• Menstruation
• Friction
• Immune suppression

Triggers vary, and outbreaks can also occur without an obvious cause.

Reducing the Risk of Transmission

Patients can lower—but not eliminate—transmission risk by:

• Avoiding sexual contact during outbreaks
• Avoiding contact when warning symptoms begin
• Using condoms or barrier protection
• Taking suppressive antivirals when appropriate
• Informing sexual partners
• Avoiding direct contact with affected skin
• Washing hands after touching the area
• Not sharing sex toys unless properly cleaned and protected

Condoms reduce risk but may not cover every area where viral shedding occurs.

Partner Testing and Communication

A partner may already carry HSV without knowing it. Type-specific testing may be considered after medical counseling, but testing limitations should be understood.

A positive herpes diagnosis does not establish when infection occurred or prove recent infidelity because the virus can remain unnoticed for months or years.

Genital Herpes During Pregnancy

Genital herpes during pregnancy requires medical guidance because transmission to a newborn can be serious.

Pregnant patients should inform their obstetrician if they:

• Have a history of genital herpes
• Develop new genital sores
• Have a partner with known HSV
• Suspect a first infection during pregnancy
• Experience symptoms near delivery

Management may involve antiviral medication and delivery planning based on infection timing, symptoms, and examination findings.

Genital Herpes and Other STIs

Genital sores can increase vulnerability to HIV transmission. Patients diagnosed with herpes may be offered testing for:

• HIV
• Syphilis
• Gonorrhea
• Chlamydia
• Hepatitis
• Other infections based on exposure

Comprehensive screening can identify infections that may otherwise have no symptoms.

Herpes Care for International Patients

Busan offers sexual health, urology, gynecology, and dermatology services for international patients requiring confidential herpes testing or treatment.

Patients should bring:

• A list of current medications
• Information about medication allergies
• Previous HSV or STI results
• Details of earlier outbreaks
• Dates of recent exposure
• Information about pregnancy
• Partner test results when available

Patients leaving Korea soon should ask how laboratory results, prescriptions, and follow-up care will be communicated.

How Long Does Treatment Take?

Consultation and lesion collection may be completed during one visit. Laboratory processing time depends on the test performed.

Antiviral treatment is commonly started promptly when symptoms strongly suggest herpes, particularly during a first outbreak. The treatment duration depends on whether therapy is for an initial episode, recurrence, or daily suppression.

Genital Herpes Treatment Cost in Busan

The total cost may depend on:

• Medical consultation
• HSV PCR or lesion testing
• Type-specific antibody testing
• Additional STI screening
• Prescription antiviral medication
• Pain management
• Follow-up appointments
• Pregnancy-related evaluation

Patients should request an individualized estimate after the doctor determines the appropriate tests and treatment.

When Should You Seek Urgent Medical Care?

Seek prompt medical attention for:

• Inability or severe difficulty urinating
• Severe or rapidly worsening pain
• Extensive genital sores
• High fever or significant weakness
• Eye pain or eye exposure
• Severe headache, confusion, or neck stiffness
• Symptoms during pregnancy
• Symptoms in an immunocompromised patient
• Signs of widespread infection

Eye symptoms require urgent assessment because ocular herpes can threaten vision.

Frequently Asked Questions

Can genital herpes be cured?

There is currently no treatment that permanently removes HSV. Antiviral medication can manage outbreaks, reduce recurrences, and lower transmission risk.
