Grouped painful blisters that break into shallow ulcers are suggestive, yet mild herpes may resemble a cut, ingrown hair or irritation. This guide explains genital HSV-1 symptoms, the names you may hear, and how testing can clarify overlapping signs. Genital HSV-1, genital herpes type 1 or herpes simplex. HSV-1 also causes many cold sores, but infection site matters.
What causes genital HSV-1?
Herpes simplex virus type 1 is a virus. It is also known as genital herpes type 1; HSV-1. 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 1 |
|---|---|
| How it spreads / is acquired | skin-to-skin contact, including oral-to-genital transmission during oral sex, even when symptoms are not obvious |
| When symptoms may appear | A first recognised outbreak can develop within days, but many people notice symptoms much later or never recognise an outbreak. |
| Useful distinguishing clue | Grouped painful blisters that break into shallow ulcers are suggestive, yet mild herpes may resemble a cut, ingrown hair or irritation. |
| Common symptom overlap | HSV-2, syphilis, chancroid, folliculitis, contact dermatitis and trauma |
Symptoms: common does not mean specific
Possible findings include painful blisters or ulcers, tingling, burning, painful urination, tender nodes, flu-like symptoms during a first episode, or no recognised symptoms. None of these, alone, confirms genital HSV-1. 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-2, syphilis, chancroid, folliculitis, contact 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?
Swab a fresh blister or ulcer for PCR as early as possible. A negative swab from an old/healed lesion does not exclude infection. Type-specific blood testing has limitations and must be interpreted carefully.
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

Appearance alone cannot confirm or exclude an infection. Clinical galleries may show intimate body areas. Photographs remain on the original publisher’s website.
Questions readers ask
Can HSV-1 cause genital herpes?
