s (ARVs) are given to slow down the HIV reproduction, which in turn increases quality of life and survival. If the patient's viral load (the amount of HIV in the blood) rebounds after being suppressed by ARVs, the virus has likely developed resistance to the ARVs. As more and more mutations conferring drug resistance develop in the HIV's genome, it becomes difficult to select an ARV that will meaningfully suppress HIV replication and keep the patient's viral load low. Salvage therapy, in this context, is the attempt to contain the replicating HIV once the usual line of treatments have been exhausted. When at least one regimen containing
