Table 3. Contribution of four components of an HIV prevention package to infections prevented.

Prevention package component percent infections prevented due
to addition of component (95% CI)1
ART (50% coverage of eligible persons) 3.4 (2.2, 4.5)
PREP (50% coverage of eligible persons) 11.7 (8.4, 15.0)
UAI (15% reduction) 21.0 (20.0, 22.0)
HIV testing increase 4.9 (1.8, 7.9)
% prevented with all 4 components2 33.9 (31.5, 36.3)

Components include ART (50% ART coverage of eligible persons from among those not already receiving ART at baseline); PREP (50% acceptance of PREP among eligible persons); UAI reduction (15% reduction), and HIV testing increase (50% reduction of persons who never have an HIV test).

1

The percent infections prevented due to component i refers to the percentage decrease in the 5 year cumulative HIV incidence with the HIV package that includes all four components compared to the HIV prevention package that includes three of the four components leaving out component i.

2

The total percent infections prevented refers to the percentage decrease in the 5 year cumulative incidence with the 4 component HIV package compared to no prevention interventions (none of the components). The total percent is not the column sum of the individual components.
