A question that has been coming up in a lot of different forms lately is the title of this post: What are HIV+ patients dying of? In high-income settings, for people who are getting treatment, the answer seems to be known, by those in the know, and perhaps the definitive work is Causes of Death in HIV-1–Infected Patients Treated with Antiretroviral Therapy, 1996–2006: Collaborative Analysis of 13 HIV Cohort Studies.

Left unanswered is what is going on with people who are not getting treatment, who are not diagnosed, and who are not living in Europe or North America.
