HIV infection, the virus that causes AIDS, is preventable. According to the CDC, HIV is transmitted through semen, blood, breast milk and vaginal fluid. Before having sex, you should know your partner history and risk factors. If you think you have put yourself at risk, talk to your doctor or your local health department about getting tested.
Practice Abstinence
Abstinence is a sure way to prevent a sexually transmitted HIV infection. Do not engage in sex until you are in a monogamous relationship and you each know each other's HIV status.
Condoms
Use a latex or polyurethane condom consistently and correctly every time you have sex, be it vaginal, oral or anal. When engaging in oral sex, a dental dam or plastic wrap should be used.
Do Not Inject Drugs
Injecting illicit drugs can be harmful and cloud your judgment about sexual activity. Additionally, dirty needles can be infected with HIV. If you do inject drugs use clean needles. And if you use these drugs, seek treatment so that you can stop.
Do Not Share Personal Items
Items that might carry traces of HIV-infected blood include razors and toothbrushes. It is not a good idea to share these items with someone who might be infected with HIV.
Pregnant Women
Pregnant women should be screened and tested if they are risk for HIV. Knowing their status can help a health care provider increase the chances that HIV will not be transmitted to the baby.
Protective Barriers
You should treat anything contaminated with bodily fluids or blood as potentially infectious. Use gloves, gowns, aprons and eyewear when handling or touching items or persons that are soiled with bodily fluids or blood. Wash your hands after exposure to prevent transmission of disease.
