Measuring HIV Incidence and Prevalence in Washington, DC Challenges and Opportunities
Availability of high-quality data are essential for obtaining reliable estimates of HIV incidence and prevalence. Any estimates from one method alone are subject to substantial uncertainty/potential bias depending upon the assumptions on which the tool/method are based. More reliable estimates of HIV incidence and prevalence can be made by critically synthesizing multiple data sources using several procedures. When independent methods reach similar conclusions, confidence in the findings is bolstered. Triangulation/periodically corroboration of different methods/different data sources will strengthen interpretation and identify variations in HIV risks. This presentation briefly reviewed the epidemics of HIV/AIDS in Washington, DC and the United States, discussed a variety of methods to measuring HIV incidence/prevalence, including CDC advances in methods (extended back-calculation and BED-CEIA based estimation), and methods and data sources in Washington, DC for measuring HIV incidence/prevalence.
