Which single intervention would do the most to improve the health of those living on less than $1 per day? Interview by Gavin Yamey.

Abstract

Background to the debate: <i>PLoS Medicine</i> is participating in the Council of Science Editors' global theme issue on poverty and human development on October 22, 2007 (http://www.councilscienceeditors.org/globalthemeissue.cfm). Over 200 scientific and medical journals are taking part. For our theme issue, we asked a wide variety of commentators worldwide—including clinicians, medical researchers, health reporters, policy makers, health activists, and development experts—to name the single intervention that they think would improve the health of those living in poverty. We also asked four individuals living in poor, rural agricultural communities in the Santillana district, province of Huanta, Ayacucho, Peru to give us their response to the question, “What do you think would do the most to improve your health and the health of your family?” (The four community members were Severino Rojas Poma, Mercedes Vargas Soto, Julián De La Cruz Chahua, and Martín Rojas Poma). Our October 2007 Editorial discusses this debate further.
