Three global health experts - Gregg Alton JD, Executive Vice President, Gilead; Ambassador Eric Goosby MD: Global Health Science, UCSF; and Stefano Bertozzi MD PhD, Dean, School of Public Health, UC Berkeley - discuss the role and responsibilities of public and private organizations in the response to the global HIV and HCV epidemics. From policy advances to facilitate access to life saving antiretrovirals for millions of patients, to challenges in regulatory infrastructure, to the rocky path for point-of-care diagnostics and treatment monitoring technologies, to the recognition that treatment is prevention and key to any containment strategy – the lessons provided by the expansion and entrenchment of the HIV epidemic, and successes and failures in the public health response are unparalleled in the global health arena.
