Achieving Viral Suppression in 90% of People Living with Human Immunodeficiency Virus on Antiretroviral Therapy in Low- and Middle-Income Countries: Progress, Challenges, and Opportunities

Abstract

Although significant progress has been made, the latest data from low- and middle-income countries show substantial gaps in reaching the third "90%" (viral suppression) of the UNAIDS 90-90-90 goals, especially among vulnerable and key populations. This article discusses critical gaps and promising, evidence-based solutions. There is no simple and/or single approach to achieve the last 90%. This will require multifaceted, scalable strategies that engage people living with human immunodeficiency virus, motivate long-term treatment adherence, and are community-entrenched and €'supported, cost-effective, and tailored to a wide range of global communities.
