If you have herpes, you’re not alone. Millions of Americans have it. Herpes has no cure. But you can control it and learn how to protect yourself and others from outbreaks.

What Is Herpes?

Herpes is a chronic (lifelong) virus. It can cause sores and discomfort. You get it from contact with someone who carries the virus. If sores occur on the lips, you have oral herpes. If sores occur on the penis or around the vagina or anus, you have genital herpes.

Herpes Outbreaks

  • The first outbreak of herpes sores is usually the most severe. Then the body’s immune system (specifically the white blood cells) produces antibodies. These antibodies help neutralize the herpes virus and help make future attacks less severe.

  • Some people have only one outbreak of sores. More commonly, an outbreak occurs every 3 to 12 months. Some people have periods of frequent outbreaks (every few weeks). Outbreaks of herpes sores may occur less frequently over time.

  • Herpes sores may appear without a cause. Outbreaks are more likely when the immune system is weak. Other viral infections (such as a cold) can cause outbreaks. Stress from a poor diet, fatigue, or emotional upset can lead to outbreaks of sores.

To Help Prevent Outbreaks

  • The best way to prevent sores is to boost your immune system. To do this:

    • Get plenty of sleep.

    • Reduce stress and tension.

    • Eat a balanced diet. Your healthcare provider may suggest taking supplements to help assure that you get all the nutrients you need.

  • To prevent oral herpes outbreaks, avoid overexposure to wind, sun, and extreme temperatures. Use sunscreen and lip balm.

  • Ask your healthcare provider about medications that can help prevent outbreaks.

How Herpes Spreads to Others

Herpes can be spread during an outbreak. But even without sores present, you can still “shed” the virus and infect others. You can take steps to prevent this.

To Protect Yourself and Others:

  • If you have an oral sore, avoid kissing and oral-genital contact.

  • If you have a genital sore, avoid intercourse. Also avoid oral-genital contact.

  • Wash your hands after touching a sore.

  • Use a condom each time you have sex. You can pass the virus even when sores aren’t present. If you’re unsure about the timing of certain kinds of physical contact, ask your healthcare provider.

  • Tell any new partners that you have herpes.
