Genital Herpes: Diagnosis and Treatment
Medically reviewed by Dr Vafa Derakshan, MBBS, FRACGP · AHPRA MED0001663310 · Last reviewed: 23 September 2026
Genital herpes is very common. Australian guidelines estimate 70 to 80% of adults carry HSV-1 and 12 to 15% carry HSV-2, and most infections are so mild or symptom-free that they're never diagnosed. When outbreaks happen, treatment helps them heal faster.
Symptoms
Sores or blisters on or around the genitals or anus, redness with itching or tingling, or painful splits in the skin. Outbreaks can come back.
How it's diagnosed
The best test is a swab taken from a sore while it's present, so book while you have symptoms. We'll send a pathology request to your phone. Blood tests for herpes aren't recommended for people without symptoms, because they don't give useful answers.
Treatment online
Herpes is treated with antiviral tablets. For a first episode, treatment usually lasts 5 to 10 days and shouldn't wait for test results. For later outbreaks, you can take a short course, or daily suppressive treatment if outbreaks are frequent. Your doctor can send an eScript to your phone.
Partners
Herpes isn't a notifiable condition and formal contact tracing isn't recommended. Your doctor can talk through how to tell partners and ways to lower the chance of passing it on.
When to be seen urgently
If you can't pass urine, go to an emergency department. It can happen with a first episode and needs urgent treatment. If you're pregnant, especially in the last trimester, tell your antenatal care team, as specialist advice may be needed.
Frequently asked questions
Can I get herpes treatment online?
Yes. Your doctor can assess you by phone or video and send an eScript for antiviral tablets, for a first episode, recurrences or daily suppression.
Is there a cure for herpes?
There's no cure, but antiviral treatment shortens outbreaks, and daily suppressive treatment can reduce how often they happen.
Can I get a blood test for herpes?
Guidelines don't recommend herpes blood tests for people without symptoms. The most useful test is a swab from a sore while it's present.
Do I need to tell my partners?
Formal contact tracing isn't recommended for herpes, but your doctor can help you work out how to talk to partners.
