                                       programme. Patients failing second-line ART are referred for specialist assessment that includes
                                       viral load (VL) and genotype testing prior to recommending third-line medicines. Adherence

                                       possibility of third-line ART failure and transmission of untreatable HIV in resource-limited settings.

                                       We report the case of an adolescent girl born in July 2000. She tested positive for HIV infection in
                                       2009 and was enrolled into care at Newlands Clinic on 30 July 2009. She is the last born in a family
                                       of three children, a paternal orphan and stays with her mother. She was vertically infected, and
                                       her mother is accessing ART at the same treatment centre. Both her siblings are HIV negative. She
                                       commenced first-line ART on 28 August 2009. Table 1 summarises ART regimens received over
