The document discusses the functional cure for HIV, highlighting the significant reduction in mortality due to the increased use of antiretroviral therapy (ART) and presenting global statistics on HIV prevalence and incidence for the year 2011. It details the role of the CCR5 gene mutation in HIV infection susceptibility and explores case studies, particularly focusing on the Berlin Patient, who underwent stem cell transplantation from a CCR5-delta32 homozygous donor, suggesting a potential path toward a functional cure for HIV. Additionally, the study outlines the results of ongoing research into HIV reservoirs and their implications for treatment outcomes.
