The model was used to project the HIV infections averted over 20\u00a0years (2016\u20132036) from the intervention to increase self\u2010testing, compared with current testing rates.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Running the intervention once would avert\u00a0&lt;\u00a02.2% infections over 20\u00a0years.
