Antiretroviral therapy initiation within 7 and 8-30 days post-HIV diagnosis demonstrates similar benefits in resource-limited settings.

We estimated the optimum time to initiate antiretroviral therapy (ART) in a retrospective observational cohort. We observed that ART initiation 7 days or less ( n  = 817) and 8-30 days ( n  = 1009) were the most important factors with viral suppression, and had similar viral suppression rate, CD4 + T-cell count increase and fractions of individuals with links at least 4 and individuals linked to recent HIV infection in HIV molecular networks. This study provides real-world evidence on the benefits of rapid ART initiation in resource-limited setting.
