While there is currently no cure for HIV, advances in treatment have made it possible for people with HIV to live long and healthy lives. We also now have more tools to halt the epidemic through treatment, prevention and education. Still, a cure would facilitate the global eradication of HIV/AIDS. For this reason, NIAID invests in basic and clinical research aimed at developing a safe, affordable and scalable cure for HIV and AIDS. Watch a video to learn about the approaches NIAID is taking to achieve a cure for HIV.
Many people involved in HIV cure research acknowledge that, much like the best treatments for HIV, a cure may consist of a combination of agents and approaches. Because of the nature of HIV infection, a cure for HIV can be defined in two ways: treatment-free remission and viral eradication.
Many people living with HIV who adhere to regular antiretroviral therapy (ART) maintain undetectable levels of the virus in their blood. While these individuals have effectively no risk of sexually transmitting HIV and are less likely to experience most symptoms and complications of HIV infection, latent virus remains in certain cells known collectively as the HIV reservoir. If people with ART-suppressed HIV stop taking their medication, virus from the reservoir rebounds to high levels. Sustained ART-free remission, sometimes called a functional cure, would allow a person living with HIV to keep latent virus suppressed without daily medication.

In a viral eradication cure scenario, HIV would be completely absent from an individual’s body. Viral eradication is generally expected to require two experimental strategies to be used in tandem. The first step would prompt latent HIV to replicate so that the cells in the HIV reservoir express HIV proteins. The second step would enhance the immune system of the person living with HIV or employ other agents to recognize and kill the cells expressing HIV proteins, thereby clearing the virus from the body.
