nPEP with a 28-day course of daily oral HIV medications lowers the risk of acquiring HIV after a potential exposure to the virus through sexual contact or from needle sharing or a needle stick.
Interventions with demonstrated potential to lower the risk of acquiring an HIV infection.
The HIV care continuum consists of several steps required to achieve a suppressed viral load in the blood: linkage to and engagement in clinical care and taking HIV medications.
