Introduction. The primary objective of national programs is the suppression of viral replication to undetectable levels and the sustaining of this virological response over time. The objective of the study was to analyze the duration of viral suppression in adult patients with HIV who started antiretroviral treatment in Peru during the period 2004-2006 with follow-up until 2012 using cumulative survival rate analysis. Methods. A retrospective observational study was conducted based on the historical cohort of patients who linked to the antiretroviral treatment national program during the period 2004 to 2006 in Peru with follow-up until December 31st, 2012. Results. Of the 6289 patients, 5142 (81.7%) initiated some treatment scheme and 4530 (72%) reached viral suppression which was sustained by variable time during the observation period. According to the cumulative survival rate 91.1% sustained viral suppression up to 1 year, 84.6% up to 2 years, 80.2% up to 3 years, 77.1% up to 4 years, 74.1% up to 5 years and 70.1% up to 6 years. Conclusions. The Peruvian cohort that began antiretroviral treatment in the initial phase of implementation of the national program, presented comparable results or above other Latin American countries in the duration of sustained viral suppression. The duration of viral suppression is a longitudinal indicator of the performance of national and local programs, which could also help to estimate the time of use of the therapeutic schemes of antiretrovirals and validate adherence.
