Genital and oral herpes are among the most common reasons travelers in Patong message us discreetly, often within hours of a new outbreak. The clinical priority is the same in every case: confirm what we are treating, start the right antiviral early, and put a plan in place for partners and future recurrences. Stigma is heavy with this diagnosis, and we work in a confidential, no-judgement setting.
What causes herpes and how it presents
Herpes is caused by herpes simplex virus, either type 1 (HSV-1) or type 2 (HSV-2). HSV-1 traditionally causes oral herpes (cold sores) and HSV-2 traditionally causes genital herpes, but with rising rates of oral sex, HSV-1 is now a frequent cause of genital infection as well. After the first infection, the virus lives dormant in a nerve cluster and reactivates from time to time. Around one in six Thai adults carries HSV-2, and many more carry HSV-1, but most have never had a clear outbreak.
A primary episode (the first ever infection) is usually the most severe. Painful clustered blisters break down into ulcers on the lips, mouth, vulva, penis, scrotum, anus or buttocks, often with fever, body aches and tender lymph nodes in the groin or neck. Some women develop pain on passing urine, and a few cannot empty the bladder at all. A primary episode typically takes 2 to 3 weeks to heal without treatment. A recurrence is milder and shorter, starting with a prodrome of tingling, itching or burning, followed by a small cluster of blisters and ulcers that crust over and heal in 5 to 10 days. Common triggers include stress, illness, sun exposure, menstruation and run-down immunity.
How we diagnose herpes at the clinic
The diagnosis usually starts with the pattern of the lesion: grouped small blisters or shallow ulcers in a typical location, with the right timeline. To confirm and to identify the type, we take a swab directly from an active blister or ulcer for PCR testing, which is the gold standard. If lesions have already healed, or if you have never had visible symptoms but a partner has been diagnosed, a type-specific IgG blood test can tell you whether you carry HSV-1, HSV-2 or both. We routinely run a full STI panel (HIV, syphilis, gonorrhoea, chlamydia) at the same visit because co-infection is common and changes management.
Antiviral treatment we use
Three oral antivirals are first-line: valacyclovir, acyclovir and famciclovir. They all work by blocking the virus from copying itself, so they cut the length and severity of the outbreak but do not eradicate the virus from the body. The regimen depends on whether this is a primary episode, a recurrence, or a pattern of frequent recurrences where daily suppression makes sense. Topical antiviral creams add little to oral therapy in genital herpes and we rarely prescribe them. Pain relief with paracetamol, ibuprofen and topical lidocaine 2 percent gel makes the first 48 hours much more bearable, and salt-water sitz baths help genital lesions heal cleanly.
| Scenario | Typical regimen | When we use it |
|---|---|---|
| Primary (first) episode | Valacyclovir 1 g twice daily for 7 to 10 days, or acyclovir 400 mg three times daily, or famciclovir 250 mg three times daily. | Start within 5 days, or while new blisters are still forming. |
| Episodic recurrence | Valacyclovir 500 mg twice daily for 3 days, or acyclovir 800 mg three times daily for 2 days, or famciclovir 1 g twice daily for 1 day. | Start at the prodrome (tingling or itching), before the blister forms. |
| Suppressive (daily) | Valacyclovir 500 to 1000 mg once daily, or acyclovir 400 mg twice daily. | Six or more outbreaks a year, or to reduce transmission to a sero-negative partner. |
| Pregnancy, from 36 weeks | Valacyclovir 500 mg twice daily until delivery. | Known genital HSV, to reduce neonatal infection. Active lesions at labour mean caesarean section. |
| Severe or immunocompromised | Higher doses, longer courses, occasionally intravenous acyclovir in hospital. | HIV, cancer treatment, transplant, or unable to take oral medication. |
Transmission, partners and sero-discordant couples
Herpes spreads by direct skin-to-skin contact, mostly during an outbreak but also through asymptomatic viral shedding between outbreaks. Condoms reduce but do not eliminate the risk, because the virus can shed from areas the condom does not cover. For couples where one partner has HSV and the other does not, the combination of condoms, avoiding sex during prodrome and visible outbreaks, and daily suppressive valacyclovir for the carrying partner cuts transmission by roughly half. We are happy to see partners together for testing and counselling, and we test the asymptomatic partner with a type-specific IgG blood test so the conversation is based on facts rather than fear.
When to see a doctor
Most herpes outbreaks are uncomfortable but uncomplicated. A small group of presentations need urgent assessment because they can cause lasting harm. Eye involvement (herpes keratitis) can threaten vision. Widespread vesicles in someone with eczema (eczema herpeticum) can become a life-threatening infection. People with HIV, cancer treatment or transplant medication can develop severe and persistent ulcers. A primary episode bad enough to stop you passing urine, or any suspicion of herpes around the time of delivery, also needs same-day review.
Eye pain, redness, light sensitivity or blurred vision with any blister near the eye or forehead (possible herpes keratitis, sight-threatening). Widespread vesicles spreading across the body in someone with eczema (eczema herpeticum). A severe primary episode with fever, inability to pass urine or unable to eat or drink. New blisters in someone with HIV, cancer treatment, transplant medication or another reason for immune suppression. Suspected herpes in pregnancy, especially in the last weeks before delivery, or in a newborn.
This is your first outbreak, you have more than 4 to 6 recurrences a year, your partner has been diagnosed, you are pregnant or planning to conceive, or you are not sure the ulcer is herpes at all. A 15-minute consultation confirms the diagnosis with PCR or blood test, starts antivirals, and sets a long-term plan including partner testing. WhatsApp +66 95 073 5550 for a same-day appointment or hotel-room visit.
Prevention and early self-care
Prevention rests on three pillars: knowing your status, treating outbreaks early, and protecting partners. Anyone with a new sexual partner benefits from a full STI screen including type-specific HSV serology. During an outbreak, avoid sexual contact from the first tingle until lesions have fully crusted and healed, wash hands carefully after touching the area, and never touch the eye before washing. Daily suppressive valacyclovir is the single most effective step for someone with frequent outbreaks or a sero-negative partner. In pregnancy, suppressive antivirals from 36 weeks markedly reduce the risk to the baby, and active genital lesions at the time of delivery are managed with caesarean section.
Summary
Herpes is common, lifelong but very treatable, and rarely a reason to feel ashamed. The clinical priorities are confirming the type with PCR or blood test, starting the right antiviral at the right time, and putting a plan in place for partners, pregnancy and recurrences. Eye involvement, eczema herpeticum, severe primary episodes and any herpes near delivery are the situations that need same-day in-person assessment.
“A herpes diagnosis is far more common than people realise, and it does not define anyone who has it. Our job is to confirm the type, ease the current outbreak, and give patients and their partners a clear long-term plan, all in one private visit.”

Frequently asked questions
How quickly does treatment work for a first herpes outbreak?
An untreated primary episode usually lasts 2 to 3 weeks. Valacyclovir 1 g twice daily started within 5 days, or while new blisters are still forming, typically eases pain within 48 hours and cuts total healing time by several days. Pain relief and salt-water sitz baths help during the worst phase.
Can I get tested for herpes without any visible symptoms?
Yes. A type-specific IgG blood test detects past infection with HSV-1, HSV-2 or both, and is the test we use for asymptomatic exposure, partner sero-status and pre-pregnancy planning. PCR from a swab is only useful if an active blister or ulcer is present.
Will I pass herpes to my partner if I am on antivirals?
The risk falls by roughly half with daily suppressive valacyclovir, combined with consistent condom use and avoiding sex during prodrome and visible outbreaks. The risk is not zero, because asymptomatic shedding still occurs. We test the asymptomatic partner so both of you make decisions with real information.
Is genital herpes always HSV-2?
No. HSV-1 is now a common cause of genital herpes through oral sex. The type matters because genital HSV-1 tends to recur far less often than genital HSV-2, and that affects whether daily suppressive therapy is worthwhile. The PCR swab tells us the type at the same time as confirming the diagnosis.
Can the clinic come to my hotel for herpes treatment?
Yes. A doctor can visit your hotel anywhere in Patong, Kalim, Kamala, Karon and Surin to assess the lesion in private, take a PCR swab, draw blood for type-specific serology and dispense the antiviral on the spot. WhatsApp +66 95 073 5550 to arrange.
When is herpes an emergency?
Eye pain or blurred vision with any blister near the eye, widespread vesicles in someone with eczema, a severe primary episode that stops you passing urine, any outbreak in pregnancy near delivery, or new blisters in a newborn or immunocompromised patient should be seen the same day. These can mean herpes keratitis, eczema herpeticum or disseminated infection, all of which need urgent treatment.
