Human immunodeficiency virus (HIV) is a sexually transmitted disease that can be deadly. HIV infection often goes undetected in patients who do not seek care. However, new research says that there may be new ways to use HIV care so that the virus becomes manageable.

For patients with human immunodeficiency virus (HIV), hepatitis C (HCV) can also be a problem. A new combination of medications, however, may effectively treat HCV in those with HIV.

HIV has been a national concern for years, but new data suggest that serious progress has been made.

According to new research, African-American and Latino people with HIV or AIDS were the least likely to take medication that could extend their lives. Researchers may now have some of the answers as to why.

Details of the passengers on the Malaysian Airlines plane shot down over Ukraine this week are starting to emerge. Among the lives lost were leading HIV/AIDS researchers on their way to the International AIDS Conference in Australia.

HIV can be hard to diagnose early because symptoms can be basic and flu-like. New research identified signs of HIV infection that may help doctors decide which patients need to be tested.

Once the HIV virus becomes resistant to a drug, that resistance is permanent. Drug resistance in HIV-infected children makes finding an effective treatment more difficult.

People at high risk for developing HIV can now take a medication to help prevent the disease. But to get the greatest protection from this medication, strict conditions must be followed.

Vaccinations can offer protection that prevents disease and saves lives. For HIV-infected patients, this protection may not last as long.
