BACKGROUND: Epidemiology's role as the 'diagnostic' arm of public health has submitted epidemiological reasoning and practice to the crossfire of oppositional social values and demands. In Latin America, the visible signs of extreme social and political authoritarianism and inequity, as well as the growing unfairness of the World economy, inspired a culture of social critique and a corresponding academic reform movement, which nurtured a profound social awareness among health scientists. Aims The authors' aim is to call attention to the need to overcome this scientific North/South divide. An imperative, at a moment when the demolition of health standards under the pressures of global economic acceleration and 'unhealthy health policies,' confront us all with the common challenge of cross-fertilizing the strengths of academic traditions from both South and North. METHODS: The present paper offers a fresh perspective from the South about the relevance of progressive Latin American public health (termed 'collective health') by highlighting a number of its hard scientific contributions which, unfortunately, remain almost unknown to mainstream medical and public health researchers outside Latin America. RESULTS: An armed form of structural greed has now placed the world on the brink of destruction. At the same time, however, fresh winds blow in the continent. CONCLUSION: This paper is an invitation to confront the menacing forces producing our unhealthy societies and an opportunity to form fraternal partnerships on the intercultural road to a better world, where only an epidemiology of dignity and happiness will make sense.
