Acquired immune deficiency syndrome

1. See the article on safe sex to learn how to reduce the chance of acquiring or spreading HIV, and other sexually transmitted diseases.
2. Try not to use intravenous drugs. If IV drugs are used, do not share needles or syringes. Many communities now have needle exchange programs, where used syringes can be disposed of and new, sterile needles obtained for free. These programs can also provide referrals to addiction treatment.
3. Avoid contact with another person's blood when the HIV status of the bleeding individual is unknown. Protective clothing, masks, and goggles may be appropriate when caring for people who are injured.
4. Anyone who tests positive for HIV can pass the disease to others and should not donate blood, plasma, body organs, or sperm. An infected person should warn any prospective sexual partner of their HIV-positive status, should not exchange body fluids during sexual activity, and should use whatever preventive measures (such as condoms) will afford the partner the most protection.
5. HIV-positive women who wish to become pregnant should seek counseling about the risk to unborn children, and medical advances which may help prevent the fetus from becoming infected. Use of certain medications can dramatically reduce the chances that the baby will become infected during pregnancy.
6. Mothers who are HIV-positive should not breast feed their babies.
7. Safe-sex practices, such as latex condoms, are highly effective in preventing HIV transmission. HOWEVER, there remains a risk of acquiring the infection even with the use of condoms, if the condom breaks. Abstinence is the only sure way to prevent sexual transmission of HIV.

The riskiest sexual behavior is unprotected receptive anal intercourse -- the least risky sexual behavior is receiving oral sex. Performing oral sex on a man is associated with some risk of HIV transmission, but this is less risky than unprotected vaginal intercourse. Female-to-male transmission of the virus is much less likely than male-to-female transmission. Performing oral sex on a woman who does not have her period carries low risk of transmission.
