Human Immunodeficiency Virus (HIV) Infection - Prevention

Prevention

You can keep from getting HIV by avoiding behaviors that might result in contact with infected blood, semen, or vaginal fluids.

• Practice safe sex to prevent HIV. Always use a condom during sexual activity, unless you are in a relationship with one partner who does not have HIV or other sex partners.
• If you do have sex with someone who has HIV, it is important to practice safe sex and to be regularly tested for HIV.
• Reduce your number of sex partners, preferably to one partner.
• Talk with your sex partner or partners about their sexual history, as well as your own sexual history. Find out whether your partner has engaged in high-risk behaviors.
• Avoid alcohol and drugs, which can impair both your judgment and your immune system. People who know and understand safer sex practices may not practice them when they are under the influence of alcohol or drugs.
• Do not share intravenous (IV) needles, syringes, cookers, cotton, cocaine spoons, or eyedroppers with others if you use drugs.

If you are HIV-positive (infected with HIV) or have engaged in sex or needle-sharing with someone who could be infected with HIV, take precautions to avoid spreading the infection to others.

• Tell your sex partner or partners about your behavior and whether you are HIV-positive.
• Follow safe sex practices, such as using condoms.
• Do not donate blood, plasma, semen, body organs, or body tissues.
• Do not share personal items, such as toothbrushes, razors, or sex toys, that may be contaminated with blood, semen, or vaginal fluids.

An HIV-infected pregnant woman can prevent or reduce the risk of spreading HIV to her baby if she takes the medicine zidovudine (ZDV, formerly AZT) during pregnancy and if she does not breast-feed her baby. The baby should also receive ZDV after birth.

If you do not regularly engage in high-risk behaviors for HIV, such as having unprotected sex or injecting drugs, and you feel you have been exposed this way, contact your doctor as soon as possible. He or she may recommend medicine if your exposure was within the past 72 hours.⁵
