Genital Herpes and HIV

Having genital herpes can increase the risk of being infected with HIV, the virus that causes AIDS, and it can cause serious problems for people living with HIV (human immunodeficiency virus).

People who have genital herpes sores are more likely to be infected with HIV during intercourse. When you develop a sore, the immune system tries to heal it, so there are many immune cells concentrated in that spot. Those are the cells that HIV infects. If HIV in semen, vaginal fluid, or blood comes in contact with a herpes sore, the risk for infection is high.

Pregnancy and Genital Herpes

Pregnant women with genital herpes should be careful -- but not overly worried -- about passing the virus on to the baby. A mother can infect her baby during delivery, often fatally. But if a woman had genital herpes before getting pregnant, or if she is first infected early in pregnancy, the chance that her baby will be infected is very low -- less than 1%. Women with genital herpes are examined carefully for any symptoms before giving birth. If sores or signs that an outbreak is coming show...

The Compound Effect of Genital Herpes and HIV

HIV and the genital herpes virus are a troublesome duo. One can worsen the effects of the other. Research shows that when the herpes virus is active, it may cause HIV to make more copies of itself (the process called replication) than it would otherwise. The more HIV replicates, the more of the body's infection-fighting cells it destroys, eventually leading to AIDS (acquired immune deficiency syndrome).

People infected with both HIV and the herpes virus may have longer-lasting, more frequent, and more severe outbreaks of herpes symptoms, because a weakened immune system can't keep the herpes virus under control as well as a healthy immune system can.

Genital Herpes and HIV Treatment Issues

It's more difficult to treat genital herpes if you also have HIV. Higher doses of antiviral drugs are often needed to treat herpes in people with HIV. Also, many people with HIV have strains of the herpes virus that are resistant to treatment with the standard antiviral drugs.

If you take antiviral drugs for genital herpes and the treatment isn't working, your doctor can test the virus you have for resistance. If the virus is resistant, there are other possible treatment alternatives, including the drugs Foscarnet and Vistide. These drugs can be given through an IV, or a Vistide gel can be applied to the herpes sores.

If you have HIV, ask your doctor if you should be tested for genital herpes. If you already know that you have herpes and HIV, discuss treatment options with your doctor.
