Human Immunodeficiency Virus 1 (HIV-1): Viral Latency, the Reservoir, and the Cure.

An estimated 37 million people globally suffer from Human Immunodeficiency Virus-1 (HIV-1) infection with 1.7 million newly acquired infections occurring on average each year. Although crucial advances in combined antiretroviral therapy (ART) over the last two decades have transformed an HIV-1 diagnosis into a tolerable and controlled condition, enabling over 20 million people living with HIV-1 to enjoy healthy and productive lives, no cure or vaccine yet exists. Developing a successful cure strategy will require a firm understanding of how viral latency is established and how a persistent and long-lived latent is generated. The latent reservoir remains the primary obstacle for cure development and most putative cure strategies proposed fundamentally address its eradication or permanent suppression.
