Strugging to a monumental re-assessing the final phases of the smallpox eradication program in India, 1960-1980

Chronicle of a consolidated success: smallpox eradication policies in Brazil (1962-1973)

The aim of this article is to understand actions taken towards smallpox eradication in Brazil, in the framework of the Smallpox Eradication campaign that took place in the 1960s and 1970s. The article argues that, in addition to the bifurcated needle and the lyophilized vaccine, epidemiological surveillance - based on the construction of instruments and protocols for health surveillance - was the third key element that guaranteed the eradication of the disease. The hypothesis is that the actions taken towards the control and eradication of smallpox contributed to the construction of new health institutions within Brazil. As an exercise of socio-historical analysis, this research was based on documentary sources (reports, newsletters and legislation), interviews with professionals directly involved in the eradication of smallpox, and part of the intellectual production on the subject.

Control, containment and health education in the smallpox-vaccination campaigns in Mexico in the 1940s

This article examines some of the changes that the Mexican vaccination programs underwent starting in 1943, the year when the National Smallpox Campaign (Campaña Nacional contra la Viruela) was established. It analyzes why a uniform and coordinated vaccination method was adopted to counter the outbreaks of this endemic disease, especially in central Mexico; the actions of its numerous and heterogeneous staff; and the reasons why smallpox vaccination was considered critical to establish a culture of prevention. In summary, the article examines why selective vaccination was chosen and the expansion of the health-education programs, topics that have been seldom addressed in historical research.

Political will and international collaborative frameworks in infectious diseases

The last few decades have been marked by a rapid expansion in the world?s population, along with an increasingly dynamic mobility of individuals. This accelerated global inter-connectedness enabled microorganisms to reach virtually any location worldwide more rapidly and efficiently than ever before, reshaping the global dynamics of pathogens. As a result, a local infectious disease outbreak anywhere in the world may almost instantaneously assume global dimensions, and should therefore be considered a global priority. The history of several infectious diseases illustrates that in addition to prophylactic and therapeutic medical interventions, the interplay of social, economic, and political factors makes a fundamental contribution to the outcome of infectious disease outbreaks. Furthermore, this multi- and cross-disciplinary interconnectedness is a key determinant of the outcome of efforts to eradicate vaccine-preventable infectious diseases. A combined framework that incorporates teachings provided by previous outbreaks, and integrates medical and biomedical interventions with contributions made by social, economic, and political factors, emerges as vital requirement of successful global public health initiatives.
