Models to Identify HIV/AIDS Cases
The first stage of the HIV care continuum is testing and screening for HIV. It is estimated that approximately 14% of people living with HIV in the U.S. are unaware of their HIV-positive status and that only 50% of people who know their status are engaged in regular HIV care.
Conducting testing and screening to diagnose and identify HIV-positive individuals is recommended by the Centers for Disease Control and Prevention and the U.S. Preventive Services Task Force as an effective tool to decrease the risk of spreading HIV and to connect people to treatment to minimize progression of the disease. The National HIV/AIDS Strategy highlights evidence that suggests when people test positive for HIV they are more likely to take precautions to prevent others from acquiring the virus. People who test positive during screening can be linked to treatment and counseling services, and knowledge of one's HIV status may lead to decreased risk-taking behavior.
Models to identify HIV/AIDS cases can be implemented in both clinical and community settings.
