A targeted approach for routine viral load monitoring in Malawian adults on antiretroviral therapy

Objectives WHO recommends HIV viral-load (VL) testing six months after antiretroviral therapy (ART) initiation and every 12 months thereafter, but cost prohibits routine, universal VL testing in many developing countries. We sought to devise a targeted approach to routine VL monitoring that could reduce cost and identify those at low risk for virologic failure (VF).
