Scientists have been trying to create a successful vaccine for AIDS for decades. Now, a new study on mice shows that an injection of protective antibodies may be the best way to fight the deadly disease.

Last summer, a breakthrough in AIDS prevention was announced: A trial of a vaginal gel had successful results. But a new trial has been scrapped after the gel was found to be ineffective.

For women living with HIV, the disease isn't the only burden they have to cope with. They also have to deal with the stigma of being infected.

If you have HIV, you should already be very cautious about your health. According to a new study, HIV puts you at higher risk for cancer. But you have some control: Lifestyle choices also contribute to risk.

If you're sexually active with multiple partners, listen up: More Americans are picking up sexually transmitted diseases (STDs). However, fewer people are infected with syphilis.

If your long-term partner has HIV, you're at a high risk for infection. But medical research is creating options to safeguard yourself and your partner against transmitting the virus.

Last year, there was fanfare in the HIV/AIDS community when scientists created a vaginal gel to prevent HIV infection. Now, a group of researchers is making headway with a rectal gel.

People with HIV/AIDS are living longer lives now, but they still have compromised immune systems. Patients and their doctors need to be wary of secondary infections.

If you're a sexually active teen, your doctor should offer to test you for HIV at least once by the time you're 18. That's the new recommendation from the American Academy of Pediatrics.

For the past 30 years, scientists have had no success developing a vaccine for AIDS. Their track record may change with the discovery of a powerful new anti-HIV antibody.
