Recurrent grouped painful genital blisters or ulcers with a prodrome of tingling/burning are suggestive; HSV-2 generally recurs and sheds more often genitally than HSV-1. This guide explains genital HSV-2 symptoms, the names you may hear, and how testing can clarify overlapping signs. Genital HSV-2, genital herpes type 2 or herpes simplex. Genital herpes can be caused by either HSV type.
What causes genital HSV-2?
Herpes simplex virus type 2 is a virus. It is also known as genital herpes type 2; HSV-2. A laboratory result should be interpreted in context: detecting an organism does not always mean it is causing the current symptoms.
| Cause | Herpes simplex virus type 2 |
|---|---|
| How it spreads / is acquired | skin-to-skin sexual contact; transmission can occur during asymptomatic viral shedding |
| When symptoms may appear | Symptoms may appear within days of acquisition, but the first recognised outbreak can occur much later and many infections are unrecognised. |
| Useful distinguishing clue | Recurrent grouped painful genital blisters or ulcers with a prodrome of tingling/burning are suggestive; HSV-2 generally recurs and sheds more often genitally than HSV-1. |
| Common symptom overlap | HSV-1, syphilis, chancroid, folliculitis, dermatitis and trauma |
Symptoms: common does not mean specific
Possible findings include painful blisters or ulcers, tingling, dysuria, tender nodes, systemic symptoms during a first episode, or no symptoms. None of these, alone, confirms genital HSV-2. Symptoms may be absent, may appear later than expected, or may improve while the infection or underlying problem remains.
What can look similar?
The differential diagnosis includes HSV-1, syphilis, chancroid, folliculitis, dermatitis and trauma. Coinfection is also possible, which is why a clinician may recommend more than one target or more than one sample site.
How is it diagnosed?
Lesion PCR from a fresh sore is the most sensitive direct test. Type-specific serology may help in selected situations but false positives and timing limitations require counselling.
When should you see a doctor promptly?
- Severe pelvic, abdominal or testicular pain
- Fever, faintness, rapidly worsening symptoms or pregnancy
- A new genital ulcer, blister or widespread rash
- Symptoms after sexual assault, or possible exposure to HIV

Questions readers ask

A fresh-lesion swab for a validated molecular test, commonly PCR.
