On 22 July 1946, the International Health Conference in New York adopted the Constitution of the World Health Organization, defining health as a state of complete physical, mental, and social well-being and establishing a multilateral agency dedicated to the attainment by all peoples of the highest possible level of health. Nearly five decades later, in the autumn of 1994, an international commission announced that indigenous transmission of wild poliovirus had ceased across the Western Hemisphere, ending three years of case investigations after the August 1991 detection in Junín, Peru. Both documents represent moments of international consensus in public health, yet they embody contrasting modes of governance: one established universal constitutional principles and regulatory powers, while the other certified an empirical absence through strict verification criteria.
This study investigates what the 1946 charter and the 1994 certification report required and how long elapsed before their mandates took operational effect. It asks three related questions: 1. What regulatory and institutional commitments did the 1946 Constitution and the 1994 polio certification report establish at the hour of their adoption? 2. How long did each instrument require to achieve formal validity or operational proof, and how did contemporary authorities structure the intervening period? 3. How do the modern decision records published by Skeptron, a studio in the RISCON family, record these temporal intervals, and what aspects of institutional responsibility do they preserve or omit?
In addressing these questions, this study contributes temporal evidence to established histories of international health. Historians have traced the organizational evolution of the World Health Organization, documenting its oscillations between broad social visions and vertical disease eradication campaigns (Cueto, Brown, and Fee 2019), the technical shift in smallpox eradication from mass vaccination to surveillance and containment (Fenner et al. 1988), and the three-year acute flaccid paralysis surveillance and laboratory audit criteria developed to certify the interruption of wild poliovirus transmission in the Americas (Robbins and de Quadros 1997). This study contributes an inquiry into institutional time: the 625-day passage between the signature of the WHO Constitution in July 1946 and its legal force in April 1948, alongside the multi-year surveillance duration separating the final detected polio case in 1991 from regional certification in 1994.
The documentary materials brought together here pair the operative articles and constitutional preambles of post-war Geneva with the technical surveillance summaries prepared in Atlanta and Washington. Alongside these historical publications stand two analytical reconstructions formulated by Skeptron, which dissect the formal bench dates, the distinction between collective treaties and separate accessions, the three-year surveillance threshold, and the evidentiary limits of post hoc retrospective judgment.
The study is organized into six chapters. Chapter 2 reviews the historical and theoretical literature on international health architecture, disease eradication certification, and the tensions between sanitary regulations and commercial sovereignty. Chapter 3 outlines the data and methods, detailing the status of the primary texts, the structure of Skeptron's decision records, and the pre-registered hypotheses in the study's ledger. Chapter 4 examines the 1946 Constitution, analysing its preamble principles, the regulatory mechanism established under Articles 21 and 22, and the 625-day interval required to bring the charter into force. Chapter 5 evaluates the 1994 polio eradication certification, detailing the criteria established by the independent certification commission, the role of active surveillance for acute flaccid paralysis, and the significance of the multi-year surveillance threshold. Chapter 6 compares the two episodes, exploring the distinction between aspirational constitutionalism and empirical certification, the temporal structure of international health acts, and the limits of modern decision records. The Conclusion summarizes the findings, discusses the study's historiographical limits, and presents the ledger's quantitative findings.
