COHP, person from a country of high prevalence with no other identifiable risk factor available. IDU, current/former injecting drug user. Late diagnosis defined as CD4 count < 350 cells/μl at diagnosis or AIDS defining illness at diagnosis. “On HAART” means the patient was on HAART for the entire duration of the study, “suppressed” was defined as all viral loads in 2012 < 50 copies/ml, with one test result of 50–499 copies/ml allowed if previous and subsequent viral load results were < 50 copies/ml.
