Herpes Simplex Virus Type 2 Infection
What is Herpes Simplex Virus Type 2 Infection?
Herpes Simplex Virus Type 2 is a common sexually transmitted infection that primarily affects the genital area. HSV-2 causes recurring outbreaks of painful sores or blisters on or around the genitals, rectum, or mouth. The virus stays in your body for life once you contract it.
More than 1 in 6 people aged 14 to 49 in the United States have HSV-2 infection. Many people with HSV-2 do not know they have it because they never develop symptoms or the symptoms are so mild they go unnoticed. The virus spreads through skin-to-skin contact during vaginal, anal, or oral sex, even when no visible sores are present.
Understanding your HSV-2 status helps you protect your health and prevent transmission to sexual partners. Regular testing allows you to make informed decisions about your sexual health and seek treatment when needed.
Symptoms
- Painful blisters or open sores on or around the genitals, rectum, or thighs
- Itching, tingling, or burning sensation in the genital area before sores appear
- Pain during urination
- Flu-like symptoms during initial infection, including fever, body aches, and swollen lymph nodes
- Vaginal discharge in women
- Headache and fatigue during outbreaks
Many people with HSV-2 have no noticeable symptoms or very mild symptoms that they mistake for other skin conditions. Some people never experience an outbreak even though they carry the virus. This is why blood testing is important for knowing your true status.

Causes and risk factors
HSV-2 spreads through direct contact with infected skin or bodily fluids during sexual activity. You can contract the virus from a partner who has HSV-2 even if they do not have visible sores. The virus sheds from the skin periodically, which means it can spread between outbreaks. Condoms reduce transmission risk but do not eliminate it completely because they may not cover all affected areas.
Risk factors include having multiple sexual partners, starting sexual activity at a young age, being female, and having another sexually transmitted infection. A weakened immune system makes outbreaks more frequent and severe. Having HSV-1, which causes oral herpes, does not protect you from getting HSV-2. Stress, illness, surgery, and menstruation can trigger recurrent outbreaks in people who already have the virus.
How it's diagnosed
HSV-2 is diagnosed through blood tests that detect antibodies your immune system makes in response to the virus. IgG antibodies indicate a past or current infection, while IgM antibodies suggest a recent or active infection. Blood tests can identify HSV-2 even when you have no symptoms or visible sores. This type-specific testing distinguishes HSV-2 from HSV-1.
Rite Aid offers confidential HSV-2 antibody testing as an add-on to our preventive health panel. Get tested at any Quest Diagnostics location nationwide and receive your results securely online. When sores are present, your doctor may also take a swab sample from the sore for laboratory testing to confirm active infection.
Treatment options
- Antiviral medications like acyclovir, valacyclovir, or famciclovir to reduce outbreak frequency and severity
- Daily suppressive therapy for people with frequent outbreaks or to reduce transmission risk to partners
- Pain relief with over-the-counter medications and warm baths during outbreaks
- Keeping the affected area clean and dry to promote healing
- Avoiding sexual contact during outbreaks and using condoms between outbreaks
- Managing stress through regular exercise, adequate sleep, and relaxation techniques
- Eating a nutrient-rich diet to support immune function
- Avoiding known outbreak triggers like excessive sun exposure or certain foods

Frequently asked questions
No, HSV-2 cannot be cured because the virus remains in your nervous system for life. However, antiviral medications can manage symptoms, reduce outbreak frequency, and lower transmission risk. Many people with HSV-2 live healthy lives with proper treatment and self-care.
Type-specific HSV-2 IgG antibody tests are about 95% accurate when performed at least 12 to 16 weeks after potential exposure. Testing too early may produce false negative results because your body needs time to develop detectable antibodies. IgM tests can help identify recent infections but are less reliable than IgG tests.
Yes, HSV-2 can spread through asymptomatic viral shedding when no sores or symptoms are present. Studies show that people with HSV-2 shed the virus on about 10% of days even without symptoms. Daily antiviral medication reduces asymptomatic shedding and transmission risk by about 50%.
Wait at least 12 to 16 weeks after potential exposure for the most accurate blood test results. Your immune system needs this time to produce enough antibodies for detection. If you develop symptoms sooner, see a doctor for a swab test of any sores that appear.
Most people with HSV-2 can have healthy pregnancies and babies. The main risk is transmission to the baby during vaginal delivery if you have an active outbreak. Your doctor may recommend daily antiviral medication in late pregnancy and cesarean delivery if sores are present at delivery time.
Common outbreak triggers include stress, illness, fatigue, weakened immune system, menstruation, sun exposure, and skin trauma. Identifying your personal triggers helps you take preventive steps. Some people experience frequent outbreaks while others rarely have symptoms after the initial infection.
Yes, telling sexual partners about your HSV-2 status is important for their health and your relationship. This conversation allows partners to make informed decisions and take protective measures. Many people with HSV-2 maintain healthy sexual relationships through honest communication, condom use, and suppressive therapy.
HSV-2 rarely causes serious complications in healthy adults beyond genital sores. However, people with weakened immune systems may develop severe infections. HSV-2 also increases the risk of contracting HIV because the sores provide entry points for the virus.
Use condoms correctly during every sexual encounter, limit your number of sexual partners, and ask partners about their STI status before sexual contact. Avoid sexual activity when your partner has visible sores. Consider asking partners to get tested before beginning a sexual relationship.
