Genital herpes is one of the conditions I see most often in the clinic. Because the painful genital ulcer is such a characteristic sign, the diagnosis is usually not difficult. What patients actually want answered is different: where did it come from, why has it happened to me, can it be cured, and how do I stop it coming back? This article takes those questions in turn.

The two strains of فيروس الهربس البسيط

1. HSV-1 — usually lives around the mouth and causes oral ulcers, but can also cause genital herpes.
2. HSV-2 — usually lives in the genital area, and is the main cause of genital herpes.

How it behaves in the body

The virus is transmitted by direct skin-to-skin contact. After the first exposure, painful genital ulcers or clusters of vesicles appear. Symptoms of a first episode settle over a couple of weeks, but the virus does not leave — it withdraws into the nervous system and lies dormant there. When immunity dips — through illness, sleep deprivation or sustained stress — the virus reactivates and symptoms return, usually more briefly and more mildly than the first time. That cycle continues for life, which is why herpes is often described as a never-ending infection.

There is one fact about transmission that is more important than everything else on this page, and it is the one most often missed. The virus can be passed on when there are no sores and nothing to see or feel. This is called asymptomatic shedding, and it means a person can transmit herpes without knowing they have it and without having done anything careless. It is not a rare quirk: when sensitive testing is used, virus is detectable on the skin of the great majority of people carrying HSV-2, on roughly one day in five to one day in ten, and the large majority of infected people have never been diagnosed and have no idea. That combination is why most new infections come from someone with no symptoms at the time rather than from someone with a visible sore. If you take one thing from this article, take that one — it changes how you think about protecting a partner, and it changes how you think about where your own infection came from.

Where did I get it, and when?

This is the question that causes the most distress in my clinic, and it is often asked with a particular fear behind it — that a partner must have been unfaithful. So let me answer it as plainly as I can.

A first outbreak does not mean a recent infection. The virus can sit dormant for months or years before it produces symptoms for the first time, and because of asymptomatic shedding it can be passed on by someone who has never had a single sore in their life and has no idea they carry it. A new diagnosis is therefore not evidence of anything about your relationship, and I would ask you not to treat it as such before you have had that conversation properly. It is also worth saying that this infection is extremely common worldwide — far more common than the number of people who talk about it — and having it says nothing about your character or your judgement.

Timing can sometimes be narrowed down, but not always, and not from the outbreak alone. If it matters to you, say so at your appointment rather than working it out from the internet.

Diagnosis and treatment

The diagnosis can often be made clinically when the appearance is characteristic. Where confirmation is needed, the options are a Tzanck smear taken directly from a vesicle, or HSV PCR — the most accurate method, which also identifies whether the strain is HSV-1 or HSV-2.

Antiviral treatment with Acyclovir, Valacyclovir or Famciclovir shortens the duration of symptoms and the period during which the virus can be transmitted. Left untreated, an episode resolves on its own over a matter of weeks — so the purpose of treatment is not to cure the infection but to shorten and soften each episode, and to reduce the risk to a partner.

Starting early is what makes the difference. These medicines work by stopping the virus multiplying, so they help most when taken as soon as an episode begins — ideally at the first warning sensation of tingling, itching or burning, before the blisters appear, rather than several days in when the ulcers are already established. For anyone with recurrent outbreaks, it is worth asking your doctor for a supply to keep at home so you can start immediately rather than waiting for an appointment. That single arrangement changes the experience of this condition more than almost anything else.

Where outbreaks are frequent, suppressive therapy — a low dose taken every day rather than only during episodes — reduces both how often they occur and the chance of passing the virus to a partner. It is worth knowing the size of that second effect rather than assuming it: daily suppressive treatment roughly halves the risk of transmission to an uninfected partner. That is a real and worthwhile reduction, and it is also not zero — which is exactly why it is used alongside condoms and honest conversation rather than instead of them. If a couple is making decisions on this, the halving is the number to plan around. It is a reasonable thing to ask about if outbreaks are affecting your life or your relationship, and it does not have to be permanent.

There is currently no approved vaccine against HSV. Because genital herpes is associated with other sexually transmitted infections, a comprehensive STI screen is worth doing at the same time rather than testing for herpes alone.

Two situations that need mentioning to a doctor specifically

Pregnancy. If you or your partner is pregnant, or planning to be, genital herpes must be raised with the obstetric team rather than managed quietly. The concern is not the mother but the baby: herpes passed to a newborn around the time of delivery is a serious infection. It is uncommon, and it is largely preventable when the team knows in advance — they can plan antiviral treatment late in pregnancy and make an informed decision about delivery. A first episode occurring during pregnancy matters more than a long-standing infection, so the history is worth giving in full. Nobody can plan around something they have not been told.

HIV testing. Genital ulcers of any cause break the skin barrier, and having them raises the risk of acquiring HIV if exposed. This is a practical reason to include HIV in the screen rather than a judgement about anybody. HIV testing is not done in the urology clinic here — at Bangkok Hospital Headquarters it is handled by the Infectious Diseases department, and I refer patients there. Testing and treatment for other sexually transmitted infections, and HPV vaccination, are available with me.

And one thing that genuinely does need urgent care rather than an appointment: if a severe first episode makes it impossible to pass urine, go to an emergency department the same day — in Thailand you can call 1669. A severe outbreak can cause enough pain and local nerve irritation to stop the bladder emptying, and that needs treating rather than enduring. Severe headache with neck stiffness and light sensitivity during an outbreak also needs same-day assessment.

الأسئلة المتكررة

هل يمكن الشفاء من الهربس التناسلي؟

لا. الهربس التناسلي الناجم عن فيروس الهربس البسيط (HSV) غير قابل للشفاء. بمجرد الإصابة، يظل الفيروس مقيماً بشكل دائم في الجهاز العصبي في حالة خاملة (سبات). ومع ذلك، فإنه قابل للإدارة بشكل كبير. تعمل الأدوية المضادة للفيروسات مثل الأسيكلوفير والفالاسيكلوفير على تقليل شدة ومدة النوبات بفعالية، وتسريع الشفاء، وتقليل خطر انتقال الفيروس إلى الشركاء.

السؤال 2: كيف تنتقل الهربس التناسلي؟

ينتقل الهربس التناسلي بشكل أساسي عن طريق الاتصال المباشر من الجلد إلى الجلد مع إفرازات المصاب أو القروح النشطة أثناء النشاط الجنسي. ينتشر فيروس الهربس البسيط من النوع الثاني (HSV-2)، الذي يسبب الهربس التناسلي بشكل رئيسي، عن طريق الاتصال التناسلي. يمكن لفيروس الهربس البسيط من النوع الأول (HSV-1)، الذي يسبب الهربس الفموي عادةً، أن يسبب الهربس التناسلي أيضًا عن طريق الاتصال الفموي التناسلي. والأهم من ذلك، يمكن أن يحدث الانتقال حتى عندما لا يعاني الشخص المصاب من قروح مرئية، وهي ظاهرة تعرف باسم "الإفراز الفيروسي اللاعرضي".

Q3: Does a first outbreak mean I was infected recently, or that my partner was unfaithful?

No, and this is worth understanding before difficult conversations happen. The virus can lie dormant for months or years before producing symptoms for the first time, so a first outbreak does not date the infection. Because the virus can also be passed on when there are no sores at all, it can be transmitted by someone who has never had symptoms and does not know they carry it. A new diagnosis is therefore not evidence of infidelity. Genital herpes is also far more common than the number of people who discuss it, and having it reflects nothing about a person’s character or judgement. If the timing genuinely matters to you, raise it at your appointment rather than trying to work it out alone.

Q4: Why does herpes genitalia keep coming back?

After the initial infection, the HSV virus hides in the nervous system in a dormant state, kept inactive by the immune system. When the immune system is weakened due to illness, excessive stress, sleep deprivation, or other medical conditions, the virus reactivates and travels back to the genital skin, causing a new outbreak. Recurrent episodes are usually shorter and milder than the first. This reactivation cycle can repeat throughout a person’s lifetime, which is why herpes is described as a never-ending viral infection.

Q5: When should I start antiviral treatment for an outbreak?

As early as possible. Antivirals work by preventing the virus from multiplying, so they help most when started at the very first warning sensation — the tingling, itching or burning that many people learn to recognise before any blister appears — rather than several days later when ulcers have formed. If you have recurrent outbreaks, ask your doctor about keeping a supply at home so you can begin immediately instead of waiting for an appointment. For frequent recurrences, daily suppressive therapy is an alternative that reduces both outbreak frequency and transmission risk to a partner.

Q6: How is herpes genitalia diagnosed?

Herpes genitalia can be diagnosed clinically when the characteristic painful genital ulcers or vesicular clusters are visible and the patient has a known history. Laboratory confirmation options include a Tzanck smear (direct swab from the lesion) or HSV PCR when direct swabbing is possible. HSV PCR is the most accurate diagnostic method and can also identify whether the strain is HSV-1 or HSV-2.

Q7: I have herpes and I am pregnant, or planning to be. What should I do?

Tell your obstetric team, and tell them early. The concern is not the mother’s health but the risk of passing the infection to the baby around the time of delivery, which is a serious infection in a newborn. It is uncommon and largely preventable when the team knows in advance, because they can plan antiviral treatment in late pregnancy and make an informed decision about how you deliver. A first episode occurring during pregnancy carries more weight than a long-standing infection, so give the full history rather than a summary. This applies equally if your partner has genital herpes and you do not.

Q8: Should I be tested for HIV as well?

It is worth including. Genital ulcers of any cause break the skin barrier and raise the risk of acquiring HIV if exposed, so testing is a practical precaution rather than a judgement. HIV testing is not performed in the urology clinic — at Bangkok Hospital Headquarters it is handled by the Infectious Diseases department, and patients are referred there. Testing and treatment for other sexually transmitted infections, and HPV vaccination, are available in the urology clinic.

Q9: What symptoms during an outbreak need urgent care?

Being unable to pass urine is the main one. A severe first episode can cause enough pain and local nerve irritation to stop the bladder emptying, and that needs same-day treatment rather than endurance — go to an emergency department, or call 1669 in Thailand. A severe headache with neck stiffness and sensitivity to light during an outbreak also needs same-day assessment. Otherwise, an outbreak that is unusually severe, not settling, or occurring alongside a condition that weakens the immune system should be reviewed promptly rather than managed at home.

Q10: How can I prevent herpes genitalia outbreaks?

Maintaining a healthy immune system is the most important factor in preventing recurrent outbreaks. This includes adequate sleep, stress management, regular exercise, and a healthy diet. For patients with frequent recurrences, suppressive antiviral therapy (daily low-dose Acyclovir or Valacyclovir) significantly reduces outbreak frequency and roughly halves the risk of transmission to an uninfected partner. Halving is a worthwhile reduction but it is not elimination, so suppressive therapy is used alongside condoms rather than instead of them. Consistent condom use also reduces, though does not eliminate, transmission risk, because the virus can be shed from skin that a condom does not cover.

Q11: Can I discuss this by video consultation?

Yes, and many patients prefer to for this particular condition. Bangkok Hospital Headquarters offers a Telemedicine service, arranged in advance by email to the Urology department at bhquro@bdms.co.th. It suits reviewing a known diagnosis, discussing suppressive therapy, and talking through what to tell a partner. A first episode is better seen in person, because confirming the diagnosis and swabbing a lesion cannot be done remotely, and because other causes of genital ulcers need to be excluded. Samitivej Sriracha is in-person only, booked through the Urology department line 088-022-1445.
