8. HIV Treatment Cascade: Majority in U.S. Have Uncontrolled Virus

alt

On the HIV treatment cascade front, the Centers for Disease Control and Prevention reported in December that less than one-third of people living with HIV in the U.S. have an undetectable viral load, with most of the drop-off attributable to people who had been diagnosed with HIV but did not go on to receive further care

According to CDC's Vital Signs report, of the 1.2 million people living with HIV in the U.S. in 2011, 86% had been diagnosed, 40% were engaged in HIV medical care, 37% were prescribed antiretroviral therapy (ART), and 30% had achieved viral suppression. The report highlighted some notable disparities, including lower rates of HIV diagnosis and viral suppression for young adults. Likewise, a study at Kaiser Permanente found the continuum of care varies by sex and age.

A survey of treatment cascades in high-income countries, presented at the International Congress on Drug Therapy in HIV Infection in Glasgow, showed that Australia and northern European countries are doing better than North America at retaining people in HIV care and achieving viral suppression.
