What is antiretroviral treatment (ART) for HIV prevention?

HIV antiretroviral treatment (ART) acts as HIV prevention by reducing the amount of HIV in serum and genital secretions. This helps people living with HIV stay healthier and reduces their risk of transmitting the virus to uninfected sexual partners.  (For information on CDC guidance and recommendations for ART for prevention of HIV transmission, refer to:

HIV negative persons also may take ART before or after HIV exposure(s) to help prevent HIV infection.  To learn more about this, explore HIV pre-exposure prophylaxis (nPrEP) and non-occupational post- exposure prophylaxis (nPEP).  (Refer to: and

What are some strategies to improve ART for HIV prevention?

Who is involved to make it work?

The effectiveness of ART for HIV prevention depends upon clinicians and other providers who collaborate to:

  • Identify new cases of HIV infection through testing
  • Link newly diagnosed persons to care, and assist them with remaining in care and adherent to ART
  • Re-link people who have dropped out of care
  • Combat stigma that affects patients’ commitment to remaining in care
  • Establish and manage efficient systems of care
