CDC Vital Signs: HIV Transmission along the Continuum of Care, 2016

March 18, 2019 – New analysis highlights the power of testing and treatment to end the HIV epidemic in the U.S.

Published on the first day of CDC’s 2019 National HIV Prevention Conference, a new CDC Vital Signs report shows that the vast majority (about 80 percent) of new HIV infections in the U.S. in 2016 were transmitted from the nearly 40 percent of people with HIV who either did not know they had HIV, or who received a diagnosis but were not receiving HIV care. Getting more people tested and in HIV care is a critical part of the proposed federal initiative, “Ending the HIV Epidemic – A Plan for AmericaExternal.”
