More than 33 million people around the world are currently living with human immunodeficiency virus (HIV). While huge progress has been made in increasing access to HIV treatment in the past decade and new HIV infections have substantially declined in some regions, the pandemic continues to outpace efforts to control it. The number of newly infected people each year outnumbers those who gain access to treatment by two to one.

Defeating HIV will require a comprehensive response, and effective programs must be scaled up to treat people already infected and prevent new infections. New tools are also needed to defeat the pandemic, and investment in research and development for new products remains essential. UCSF researchers address issues across the range of HIV/AIDS studies.
