Virological treatment failure and associated factors among adults on first-line antiretroviral therapy in West Hararghe, Ethiopia

Virological failure on first-line ART was found to be significantly high in West Hararghe. Factors such as undernutrition, non-disclosure of serostatus, interruption of ART doses, and the use of DTG-based regimens were identified as significant predictors of virological treatment failure. Healthcare providers should focus on the accelerated initiation of ART (preferably with a DTG-based regimen) and supplemental nutritional therapy for patients with undernutrition.
