Recurrent Genital Herpes
What is Recurrent Genital Herpes?
Recurrent genital herpes is a chronic viral infection caused by herpes simplex virus type 2, also called HSV-2. Once you contract the virus, it remains in your body for life. The virus lives quietly in nerve cells near your spine, in an area called the sacral ganglia.
Most of the time, the virus stays dormant or inactive. However, it can reactivate and travel down nerve pathways to your skin. This causes outbreaks of painful blisters or sores in the genital area. These outbreaks typically happen several times per year, though frequency varies widely from person to person.
Between outbreaks, you may have no symptoms at all. The virus is still present in your body, but it is not actively causing lesions. Understanding your infection status through blood testing helps you make informed decisions about treatment and prevention.
Symptoms
- Painful blisters or sores on or around the genitals, buttocks, or thighs
- Tingling, itching, or burning sensation before sores appear
- Pain during urination if urine touches sores
- Flu-like symptoms during outbreaks, including fever and swollen lymph nodes
- Genital pain or discomfort
- Scabbing as sores heal over one to two weeks
Some people experience frequent outbreaks while others have only occasional recurrences. Many people with HSV-2 have very mild symptoms or none at all, making them unaware they carry the virus.

Causes and risk factors
Recurrent genital herpes is caused by reactivation of HSV-2 that you contracted during an initial exposure. The first outbreak usually happens within two to twelve days after sexual contact with someone who has the virus. After that, the virus moves into nerve cells where it remains dormant between outbreaks.
Several factors can trigger the virus to reactivate. Stress weakens your immune system and is a common trigger. Illness, fatigue, menstruation, and immune suppression can also cause outbreaks. Sun exposure, friction during sex, and certain foods may trigger recurrences in some people. Each person has different triggers, and identifying yours can help reduce outbreak frequency.
How it's diagnosed
Recurrent genital herpes is diagnosed through visual examination during an active outbreak and confirmed with laboratory testing. Your doctor may swab a sore to test for HSV-2 DNA. Blood testing detects antibodies your immune system made in response to the virus.
The HSV-2 IgG antibody test confirms chronic infection and is useful even when you have no active symptoms. Rite Aid offers HSV-2 IgG testing as an add-on to help you understand your infection status. Knowing whether you carry the virus helps you make decisions about suppressive therapy and protecting partners.
Treatment options
- Antiviral medications like acyclovir, valacyclovir, or famciclovir to shorten outbreaks
- Daily suppressive antiviral therapy to reduce outbreak frequency by 70 to 80 percent
- Stress management through meditation, exercise, or therapy
- Adequate sleep and rest to support immune function
- Nutritious diet rich in lysine, found in fish, chicken, and legumes
- Limiting arginine-rich foods like chocolate, nuts, and seeds during outbreaks
- Avoiding triggers you have identified through tracking your outbreaks
- Using condoms and disclosing status to sexual partners to reduce transmission

Frequently asked questions
Outbreak frequency varies widely between individuals. Some people have one or two outbreaks per year, while others have six or more. The first year after initial infection typically has the most outbreaks. Over time, many people experience fewer and milder recurrences as their immune system adapts to the virus.
Yes, you can transmit HSV-2 even without visible sores or symptoms. This is called asymptomatic viral shedding. The virus can be present on skin surfaces even when you feel completely normal. Using condoms and taking daily suppressive antiviral medication reduces transmission risk to partners.
HSV-1 typically causes oral herpes or cold sores, while HSV-2 usually causes genital herpes. However, either virus can infect either location. HSV-2 is more likely to cause recurrent genital outbreaks than HSV-1. Blood tests can distinguish between the two virus types.
No, antiviral medications do not cure herpes or remove the virus from your body. Suppressive therapy means taking antiviral medication daily to keep the virus less active. This reduces outbreak frequency and decreases the chance of transmitting the virus to partners. The virus remains dormant in nerve cells.
Common triggers include physical or emotional stress, illness, lack of sleep, and weakened immune function. Menstruation, sun exposure, friction during sex, and certain foods may also cause outbreaks. Triggers are individual, so tracking your outbreaks can help identify your specific patterns.
The HSV-2 IgG antibody test is highly accurate for detecting chronic infection. It takes three to twelve weeks after initial exposure for antibodies to develop, so early testing may be falsely negative. The test distinguishes HSV-2 from HSV-1 and confirms infection even when you have no active sores.
Some evidence suggests that foods high in lysine may help reduce outbreaks, while arginine-rich foods may trigger them. Lysine is found in fish, chicken, and legumes. Arginine is present in chocolate, nuts, and seeds. A balanced diet that supports overall immune health is most important.
For most people with healthy immune systems, recurrent genital herpes is not medically dangerous. It causes discomfort and social concerns but does not affect internal organs. However, the infection can be serious for people with weakened immune systems or newborns exposed during delivery.
Daily suppressive antiviral therapy reduces outbreak frequency by 70 to 80 percent. Managing stress, getting adequate sleep, eating nutritious foods, and avoiding your personal triggers also helps. Some people find that consistent lifestyle habits reduce recurrences over time.
Yes, testing is valuable even without symptoms since many people with HSV-2 have mild or no symptoms. The HSV-2 IgG blood test confirms whether you have been infected. Knowing your status helps you make informed decisions about treatment, prevention, and protecting partners.
