What is the continuum?

Much effort in HIV prevention programs involves identifying disproportionately-impacted populations to target limited resources. Surveillance data is often used to identify patterns and trends in the HIV epidemic over time. Findings from the HIV Prevention Trials Network (HPTN) 052 clinical trial showed that treatment greatly reduced HIV transmission due to the substantial reduction in circulating HIV virus. Effective treatment requires successful HIV diagnosis as well as linkage and retention in HIV care - this is the HIV care continuum. To be the most impactful, public health strategies that address gaps in the HIV care continuum will require detailed information on disproportionately impacted populations.

HIVContinuum is an interactive map illustrating the HIV care continuum in several large cities in the United States. The maps depict the following five HIV care continuum elements:

  1. New HIV diagnoses
  2. Late HIV diagnoses
  3. Linkage to HIV care
  4. Engagement in HIV care
  5. Suppressed HIV viral load
  6. Users can filter each indicator by sex, race/ethnicity and age.
