Herpes

What Is Herpes?

Herpes simplex virus (HSV) is a viral infection that causes painful blisters on or around the genitals (or mouth). There are two types: HSV-1 (usually oral) and HSV-2 (usually genital), though either can infect either area. Once you have it, the virus stays in your body for life, but it's totally manageable. You won't have symptoms constantly—outbreaks come and go, and you can live completely normally between them.

How Do You Get It?

Herpes spreads through skin-to-skin contact with someone who has the virus, usually during sexual contact. You're most contagious when you have visible blisters, but transmission can happen even without symptoms (called shedding). You can get it from someone with genital herpes even if they don't currently have an outbreak.

Symptoms

• Painful blisters or ulcers on the genitals, anus, or mouth—first outbreak is usually the worst
• Tingling, burning, or itching before blisters appear (this is called a prodrome—it's a warning sign)
• Flu-like symptoms with the first outbreak: fever, headache, muscle aches, swollen lymph nodes
• Painful urination or difficulty peeing when blisters are present
• First outbreak lasts 7-10 days; later outbreaks are usually shorter (3-5 days) and less severe
• Outbreaks can be triggered by stress, illness, hormonal changes, or physical irritation

Testing & Diagnosis

Herpes is diagnosed by visual inspection during an outbreak, or through a blood test (serology) that detects antibodies to HSV-1 or HSV-2. A swab of a blister can also confirm the diagnosis.

Irish clinics offering tests:

• Your GP (free)
• Sexual Health Clinics (free on the HSE)
• Brook Ireland (sexual health service for young people)
• Private sexual health clinics

If you think you have herpes, get tested during an outbreak for the most accurate diagnosis—it's harder to confirm without active blisters.

Treatment & Management

There's no cure for herpes, but antiviral medications make it very manageable. They reduce the severity and length of outbreaks and can lower the risk of transmission to partners.

What to expect:

• Antiviral medications: aciclovir, valaciclovir, or famciclovir—usually taken for 7-10 days during an outbreak
• Suppressive therapy: taking antivirals daily to reduce outbreak frequency and transmission risk (often recommended if you have frequent outbreaks or a partner who's HSV-negative)
• Pain relief: over-the-counter paracetamol or ibuprofen, ice packs, loose clothing
• Keep the area clean and dry during outbreaks
• Avoid sexual contact until blisters are completely healed

Living with Herpes

Herpes is a chronic condition, but it's not serious or dangerous. Most people with herpes have occasional outbreaks and live completely normal lives—including having sex, having relationships, and having children. Between outbreaks, you're symptom-free. The virus doesn't damage your organs or cause long-term health problems.

Open communication with sexual partners is important so they can make informed decisions about their own risk. If your partner is HSV-negative and you want to reduce transmission risk, you can take daily antivirals and use condoms.

Prevention

• Avoid sex during outbreaks—this is the best way to prevent transmission
• Condoms—reduce but don't eliminate transmission risk (herpes can be transmitted from areas not covered by condoms)
• Antiviral suppressive therapy—significantly reduces transmission risk for partners
• Open communication with partners about your status
• Don't have oral sex if you have oral herpes blisters

Support & Resources

Herpes is really common—loads of people have it. There's nothing to be ashamed of. Irish sexual health clinics see it constantly and can give you straightforward information about management and living with the virus. If you're worried about disclosing to a partner, your clinic can help you figure out what to say and when.

Many people find that once they've had a few outbreaks and learned their triggers, they develop a routine that makes it very manageable. You can absolutely have healthy relationships, fulfilling sex lives, and children if you have herpes.
