WHO Commission on the social determinants of health: a bold new venture.

The author reflects on the significance of the World Health Organization (WHO) Commission on Social Determinants (CSDH). Accordingly, with CSDH, the two worlds of science and policy have collided in an exceptionally productive way, stressing that the commission's searchlight has been sweeping. The author implies that CSDH has framed new strategies for international, national and even local stakeholders in trying to reach out in creating coalitions as well as collaborations at a variety levels.
