“Beginning in 2012, ONE set out to write an annual accountability report, tracking just how much (or how little) progress was being made toward [ending AIDS]. And in this year’s report … we find encouraging news: if current rates of acceleration are sustained, we will achieve the beginning of the end of AIDS by 2015,” Erin Hohlfelder, ONE’s policy director for global health, writes in the Bill & Melinda Gates Foundation’s “Impatient Optimists” blog. She examines the factors behind this progress as well as challenges ahead, and writes, “[M]aking the beginning of the end of AIDS a reality requires new resources, new political commitment, and new energy. We hope that the findings of this report call attention to where the world has collectively fallen short, but that it also provides a source of encouragement and inspiration” (11/26).
