What the literature leaves open
PHEIC versus “Pandemic” The declaration of a PHEIC and the subsequent classification as a pandemic are commonly conflated in public discourse. Legally they differ. The PHEIC is explicitly regulated in Article 12 IHR (2005) and represents the highest formal alert level under international law. It activates a procedural mechanism and authorises the Director-General to issue temporary recommendations. The “pandemic declaration” by contrast has no explicit legal basis in the WHO Constitution or the IHR. It is a communicative act by which the Director-General characterises the scope and severity of global spread. It therefore lacks the procedural safeguards, defined criteria, and binding effects associated with a PHEIC. As the WHO’s Legal Counsel stated during the COVID-19 outbreak, “the IHR contain no legal definition of ‘pandemic’; it is a descriptive term used for risk communication”. 4 / 10 Björn Paulini · The Legal Mandate of the WHO in Declaring a Pandemic Absent a codified trigger, the pandemic declaration falls into the realm of soft-law normative guidance. Its authority rests on expertise and reputation rather than on treaty obligation. 3.2 Soft Law as Theoretical Frame Soft law occupies an intermediate position between political statements and binding legal instruments. It encompasses resolutions, declarations, codes of conduct, and guidelines that, although not binding, influence state conduct through legitimacy, expertise, and expectation (Burris & Lin, 2021; Quintana, 2020). The WHO’s pandemic declaration illustrates this mechanism. It creates a normative expectation of action by signalling that the global health situation has reached a qualitatively new stage requiring coordination and solidarity. The theoretical literature identifies three functions of soft law in global governance: gap-filling (issues without consensus for hard law); flexibility (adaptation to scientific and political uncertainty); norm entrepreneurship (shaping customary practice and institutional identity). Applied to the WHO, soft law enables rapid communication and mobilisation while blurring the lines of accountability. Given the enormous political and economic consequences of a pandemic declaration — affecting trade, mobility, and human rights — its non-binding character raises the question whether such authority should remain wholly discretionary. 3.3 The COVID-19 Case During COVID-19, the WHO’s decision sequence followed the IHR mechanism only up to the PHEIC phase. On 22–23 January 2020 the Emergency Committee failed to reach consensus; the Director-General therefore refrained from declaring a PHEIC.
The Legal Mandate of the WHO in Declaring a Pandemic: Between Soft Law and Binding Obligations · 2026 · DOIThis review has several limitations. First, it was designed as a structured narrative review rather than a formal systematic review, and is therefore inherently more susceptible to selection bias. Second, although we applied explicit search concepts and inclusion/exclusion criteria, we prioritized policy-relevant, implementation-focused, and high-yield literature, which may have led to underrepresentation of some region-specific or disease-specific studies. Third, we did not perform a formal risk- of-bias assessment or quantitative meta-analysis. Accordingly, this manuscript should be interpreted as a policy- and implementation-oriented synthesis rather than an exhaustive evidence appraisal.

What’s in a word? The framing of health at the regional level: ASEAN, EU, SADC and UNASUR · 2015 · DOIIt finds that characteristics associated with NPI support vary widely by region, possibly because of cultural variation and prior experience, and that minority groups tend to be less supportive of NPIs when arrest is the consequence of noncompliance.
Predicting support for non‐pharmaceutical interventions during infectious outbreaks: a four region analysis · 2014 · DOIIt seeks to contribute, first, to strengthening the field of LMIC health policy analysis by highlighting gaps in the literature and generating ideas for a future research agenda and, second, to thinking about the value and applicability of qualitative synthesis approaches to the health policy analysis field.
Mapping the existing body of health policy implementation research in lower income settings: what is covered and what are the gaps? · 2014 · DOINCD control and monitoring of programme funding should occur at the country and regional levels, since insufficient data on global health financing makes comprehensive auditing of funds nearly impossible.
The authors show how the relatively new method of respondent-driven sampling can be used successfully in an Australian setting to recruit people who inject drugs (PWID); however, as they argue, the capacity of respondent-driven sampling to produce population estimates remains unclear.

Half a Century of Wilson & Jungner: Reflections on the Governance of Population Screening · 2020 · DOIConclusion Men in the community of rural Jérémie, Haiti, have limited knowledge of illness and disease, which may stem from insufficient resources being allocated to their health care.
Therefore, in order to improve the health of both the men and their family members in this community, novel and targeted approaches to disseminate important health information to these men should be further investigated and readily implemented.
