As a World Bank staff member, I feel privileged to have participated in two landmark global public health events.
In June 2001 at a UN General Assembly Special Session, world leaders collectively acknowledged—for the first time—that a concerted global response was needed to arrest the HIV/AIDS pandemic. This led to the establishment of the Global Fund  and bilateral initiatives such as PEPFAR , which helped fund a scaled-up response to HIV/AIDS , as well as to malaria and tuberculosis. The net result for the most part has been impressive: a dramatic expansion in access to treatment that has saved millions of lives, a significant reduction in the vertical transmission of HIV (mother to child), technological progress resulting in cheaper, more effective treatments, and better knowledge about HIV transmission to guide prevention efforts—while highlighting the need to revamp health systems  to make the effort sustainable.
I’m in New York this week at the UN Summit on Non Communicable Diseases (NCDs), where more than 30 heads of state, 100 ministers, international agencies, and civil society organizations are discussing a pressing global health issue: NCDs . This is a policy nod in the right direction, as NCDs have been largely ignored in development circles even though they cause two-thirds of all deaths in the world (most of them prematurely) and long-lasting ill health and disability, and due to NCDs’ chronic nature, increase the risk of impoverishing millions of people who lack or have limited access to health systems.
In spite of the high expectations for the Summit, there is a sober realization that we are living in a different world than in 2001. Because the severity of the economic slowdown and fiscal deficits—particularly in the developed world—may constrain international assistance in the upcoming years, there is a growing understanding that countries will need “to do more with less” and that they “cannot treat their way out of the NCD challenge” as stressed in a World Bank report launched prior to the Summit.
So, I am optimistic that the post-Summit will bring forward some sound and effective approaches to deal with NCDs. The last ten years of global public health history offer multiple lessons to guide the response, particularly to avoid the false dichotomies of communicable versus non-communicable diseases, prevention versus treatment, and vertical programs versus health systems—they are mutually reinforcing. And, the World Bank, as a multisectoral institution, is well-positioned to assist countries in adapting (I would like to stress adapting and not adopting.) those lessons to their respective institutional and cultural realities—particularly in dealing with some of the social determinants of behaviors (e.g., smoking) and biological risks (e.g., obesity, hypertension due to poor diets high in trans fats, saturated fats, salt, and sugary drinks) that are associated with the onset of NCDs, as well as to strengthen the health services centered around a strong primary care system and universal health financing arrangements.
