Projected outcomes under different testing strategies.

* Model-projected new HIV infections in the UK between 2013 and 2022 under status quo testing and treatment levels, and projected number of averted infections with increased testing and treatment in parentheses. Three scenarios for the reduction in risky sexual behavior following HIV diagnosis are given.** Incremental costs and quality-adjusted life years (QALYs) discounted to the present, are relative to the status quo, assuming a 25% reduction in risky sexual behavior following HIV diagnosis.†Strategies that are dominated, i.e., have higher costs but generate fewer health benefits than a combination of other strategies.
