What is Herpes Type 2?

Herpes Type II, HSV-2 is a sexually transmitted infection caused by the herpes simplex viruses. Most genital herpes is caused by HSV-2, which means there is no cure for it. Medicines only shorten the duration of the flare ups.

1. 1 million new cases per year and 45 million people infected in the United States.

2. How common is genital herpes?

One in six Americans 12 and older has genital herpes. There are more individuals in the U.S. living with genital herpes than with any other STI; this is because a person who acquires a herpes infection remains infected for life.  It is caused by 2 main types of herpes simplex viruses:

HSV-1 - primary infection mostly in childhood causing oral herpes or cold sores.

HSV-2 – Historically, genital herpes was mainly caused by HSV-2, but the trend appears to be changing. 22% of the U.S. population or about 50 million people have HSV-2 infections.

3. What are the symptoms of herpes?

Most people infected with HSV-2 are not aware of their infection. If signs and symptoms occur during the outbreaks, they can be quite pronounced. The first outbreak usually occurs within two weeks after the virus is transmitted, and the sores typically heal within two to four weeks.

Blisters & sores - Small blisters appear and burst within a day or so to form ulcers. These can be very painful clusters, which are raw and may break open. In some cases, the sores may be minor and go unnoticed but can still be passed on to a partner. The sores will come and go; some people have frequent outbreaks, while others go years between outbreaks.

Flu-like symptoms - fatigue, fever, aches, general run-down feeling, nausea 2-7 days after exposure.

You can get treatment for the symptoms, but you cannot cure the disease. You have it for life.  Reoccurrences cause physical and emotional stress.

More than 90% infected with HSV-2 have recurrence during first year.

4. How do you get Herpes Type II?

Mainly direct contact with infected body fluids, such as semen and vaginal fluids.  Occurs when the virus enters through small cuts/abrasions on the genitals, lips, mouth, or skin.  The virus causes a lesion at the point of entry and also travels “up” peripheral nerves to enter the nervous system where it resides for long periods of time. (Source: CDC Fact Sheet: Genital Herpes.  Accessed 6/25/10).

5. What is the treatment for Herpes Type II?

There is no treatment that can cure herpes, but antiviral medications can shorten and prevent outbreaks during the period of time the person takes the medication.  In addition, daily suppressive therapy for symptomatic herpes can reduce, but not eliminate the transmission to partners.

You can infect others even if you are having no symptoms or problems at the time.

Right before or during an outbreak, a person is highly contagious.  50% of people infected are not aware they are infected.  (Source:  FM Cowan, AM Johnson, R Ashley, British Medical Journal, 1994)

6. How does Herpes Type II affect an unborn baby?

If an infected woman has a baby, 30-50% of vaginally delivered infants become infected. The baby picks up the infection during the birth process. The baby may be mentally retarded or have neurological problems, though it’s rare. Doctors can deliver the baby by C-section to avoid infecting the baby. 50% cases of newborn infection occurs to mothers with no known history of genital infection. (Source: Harger JH.

7. Can condoms protect a person from Herpes Type II?

Condoms have been shown to be ineffective in the prevention of Herpes. Since the virus is transmitted by skin-to-skin contact, condoms are likely to be less effective in reducing the transmission of herpes than they are for infections transmitted by body fluids.  Condoms do not cover all the skin in the genital area and sex with an infected person can result in an infection, even when condoms are used. Condoms, if used consistently and correctly still leave a 50% or more chance of transmission. (Source:  British Medical Journal, 1994 and the U.S. Department of Health and Human Services, May 2001)

8. How can herpes be prevented?

The most effective way to avoid transmission of sexually transmitted diseases, including genital herpes, is to abstain from sexual activity  until marriage, and your spouse does the same.
