  • One model found that targeted HIV counseling and testing performed better than opt-out testing in terms of expense, number of newly diagnosed HIV-infected patients, and reduction of HIV transmission[Holtgrave 2007]
  • Revised CDC guidelines advocate that clinical judgment should be used to decide the content, extent, and timing of counseling
  • Another model suggested that nearly universal annual screening of adults with immediate initiation of ART for all those infected would reduce incidence significantly and bring the HIV epidemic to a halt[Granich 2009]
