International Health Regulations: WHO, National Authorities and Global Health Security

The International Health Regulations (IHR) are the product of more than a century and a half of attempts to reconcile epidemic control with the movement of people, goods and states across borders. Their institutional ancestry lies in the International Sanitary Conferences beginning in Paris in 1851, when European governments confronted a recurring problem: diseases such as cholera, plague and yellow fever could move along the same commercial and maritime routes that connected the major centres of the nineteenth-century world economy. Quarantine was therefore no longer merely a domestic administrative measure. It had become an instrument of international relations, capable of protecting populations while simultaneously obstructing trade, navigation and diplomatic intercourse.

The nineteenth-century sanitary regime emerged from this tension. The 1892 International Sanitary Convention represented an early attempt to establish common rules for cholera control, while the creation of the Office International d’Hygiène Publique in Rome in 1907 gave international public health a more permanent institutional form. After the establishment of the World Health Organization in 1948, the earlier sanitary conventions were progressively consolidated into a global framework. The International Sanitary Regulations of 1951 were subsequently revised and renamed the International Health Regulations in 1969, reflecting a widening conception of international disease control.

The decisive transformation came in the late twentieth and early twenty-first centuries. The eradication of smallpox demonstrated the possibility of coordinated international disease control, but the emergence of HIV/AIDS, viral haemorrhagic fevers, antimicrobial resistance and previously unrecognised infectious diseases exposed the limitations of a regulatory system centred on a relatively narrow catalogue of diseases. The SARS outbreak of 2002–2003, particularly the controversy surrounding delayed notification and restricted access to information from China, became a defining episode in the subsequent reconstruction of the international system. The lesson was institutional rather than merely epidemiological: an effective global health regime required states to detect unusual events within their territories, communicate them rapidly and permit international assessment before an outbreak became an international crisis.

The revised IHR were adopted by the World Health Assembly in 2005 and entered into force in 2007. Their architecture moved beyond a fixed list of diseases toward an all-hazards system, under which states are expected to develop capacities for surveillance, risk assessment, notification and response. The central legal concept became the public health emergency of international concern (PHEIC)—a mechanism through which an outbreak could acquire international significance even before its ultimate epidemiological consequences were fully known.

The IHR therefore operate at the intersection of national sovereignty and international obligation. States retain primary responsibility for public health within their territories, yet the consequences of an outbreak may extend far beyond national jurisdiction. The Regulations require states to maintain specified core capacities, establish systems for surveillance and response, notify WHO of events that may constitute international emergencies, and maintain designated National IHR Authorities and National IHR Focal Points capable of continuous communication with the WHO. The legal problem is consequently not the disappearance of sovereignty, but its coordination with a system in which disease can cross borders faster than conventional governmental procedures can respond.

The history of the IHR also demonstrates that notification is a political and economic act. Governments may face domestic embarrassment, commercial losses, restrictions on travel, disruption of trade and damage to tourism when an outbreak is disclosed. The rational state response to these incentives may therefore be to delay, minimise or control information. This creates one of the fundamental structural problems of global health governance: the state that reports an epidemic first may bear immediate economic and political costs, while the international community receives the principal benefit of early warning. The IHR attempt to institutionalise a mechanism through which national reporting becomes an international public good.

The 2009 H1N1 influenza pandemic produced the first PHEIC under the revised framework. Subsequent declarations concerning polio, Ebola and Zika demonstrated that the mechanism could be applied to different epidemiological and geographical circumstances. The West African Ebola epidemic of 2014–2016, particularly in Guinea, Liberia and Sierra Leone, exposed more fundamental weaknesses. The outbreak demonstrated that legal obligations cannot substitute for functioning laboratories, trained personnel, surveillance networks, hospitals, logistics, financing and trusted institutions. The declaration of a PHEIC on 8 August 2014 was followed by a large international mobilisation, including action through the United Nations Security Council and the United Nations Mission for Ebola Emergency Response (UNMEER).

The IHR consequently developed into more than a treaty concerning the reporting of infectious diseases. They became part of a wider architecture of global health security, encompassing epidemiological surveillance, emergency response, points of entry, international travel, trade, laboratory systems, information exchange and institutional preparedness. The experience of the Ebola crisis also exposed the inadequacy of self-reported preparedness assessments and strengthened arguments for independent evaluation, sustainable financing and stronger national health systems.

A further conflict concerns the relationship between pathogen information and international equity. The dispute involving Indonesia and H5N1 influenza virus samples in 2006 demonstrated that the sharing of biological materials cannot be separated from questions of sovereignty, pharmaceutical research, intellectual property and access to vaccines. The subsequent Pandemic Influenza Preparedness Framework of 2011 represented an attempt to connect pathogen sharing with benefit-sharing. The underlying question remains central to contemporary global health law: who supplies biological information, who develops commercial products from it, and who receives the resulting vaccines, medicines and technologies?

The modern IHR must also be understood within the expanding One Health framework. Zoonotic diseases emerge from interactions among humans, animals and ecosystems; antimicrobial resistance crosses hospitals, farms, food systems and national borders; environmental degradation can alter the geographical conditions under which pathogens circulate. International health security therefore increasingly intersects with veterinary surveillance, agriculture, environmental governance, food systems and ecological change.

The historical trajectory from Paris in 1851 to the WHO framework of the twenty-first century reveals a fundamental transformation. International epidemic governance began with quarantine and maritime sanitation, developed through conventions governing specific diseases, and ultimately became a comprehensive system for managing transnational biological risk. Its continuing challenge is institutional: how can sovereign states preserve jurisdiction over their territories while creating sufficient transparency, capacity, financing, scientific cooperation and mutual accountability to prevent a local outbreak from becoming a global crisis? The future development of the IHR will depend less upon the creation of abstract international authority than upon the construction of reliable mechanisms connecting national capacity, international notification, independent assessment, pathogen sharing, equitable access, emergency financing and global cooperation.

International Health Regulations: The Global Legal Core

International Health Regulations (IHR)

↔ Global Health Governance
↔ International Law
↔ Global Health Security
↔ WHO
↔ State Sovereignty
↔ Public Health Emergency of International Concern (PHEIC)
↔ International Disease Control

The IHR form the central legal architecture connecting national public-health systems with the international management of diseases and other health risks capable of crossing borders. The present framework places obligations on States Parties concerning prevention, surveillance, notification, verification, preparedness and response, while requiring WHO to maintain global early-warning and coordination functions. Historical Evolution of International Sanitary Law

International Sanitary Conferences, 1851

↔ Quarantine
↔ Cholera
↔ International Trade
↔ Maritime Health
↔ European Diplomacy

International Sanitary Convention, 1892

↔ Disease-Specific Regulation
↔ Quarantine Law
↔ International Navigation

Office International d’Hygiène Publique, Rome, 1907

↔ Permanent International Health Administration
↔ International Health Information
↔ Institutional Public Health

World Health Organization, 1948

↔ International Sanitary Regulations
↔ Global Disease Control
↔ Modern International Health Law

IHR Revision, 2005

↔ SARS
↔ Emerging Infectious Diseases
↔ All-Hazards Approach
↔ PHEIC
↔ National Core Capacities

The historical movement is therefore:

Quarantine → International Sanitation → Disease Notification → International Health Administration → Global Surveillance → Health Emergency Governance

Sovereignty and International Obligation

State Sovereignty

↔ Territorial Jurisdiction
↔ National Public Health Authority
↔ International Responsibility

Sovereignty

→ gives the State primary authority over health within its territory

International Disease Spread

→ creates consequences beyond territorial jurisdiction

IHR

→ connects national jurisdiction with international notification and cooperation

This produces one of the fundamental structures of the IHR:

Sovereignty → Responsibility → Notification → International Cooperation

The IHR therefore do not simply replace national authority with international authority. They create a framework in which national authority becomes part of an international disease-control system.

Detection → Assessment → Notification → Response

Disease Detection

↔ Surveillance
↔ Laboratories
↔ Health Information Systems
↔ Human Resources

Risk Assessment

↔ Epidemiological Intelligence
↔ Annex 2
↔ Public Health Risk

Notification

↔ National IHR Focal Point
↔ WHO
↔ International Early Warning

Response

↔ Emergency Management
↔ Health Services
↔ Containment
↔ International Assistance

The operational logic of the IHR can therefore be represented as:

Detect → Assess → Notify → Verify → Respond → Contain → Recover → Learn

The Regulations require States to maintain capacities to detect, assess, notify and respond, while WHO maintains international surveillance and coordination functions.

National Core Capacities

Legislation and Policy

↔ Legal Authority
↔ IHR Implementation
↔ Government Coordination

IHR Coordination

↔ National IHR Focal Point
↔ WHO Contact Points
↔ Intergovernmental Communication

Financing

↔ Preparedness
↔ Emergency Response
↔ Health-System Capacity

Laboratory Capacity

↔ Diagnosis
↔ Pathogen Identification
↔ Genomic Surveillance

Surveillance

↔ Early Warning
↔ Epidemiology
↔ Disease Detection

Human Resources

↔ Field Epidemiology
↔ Laboratory Workforce
↔ Emergency Medical Workforce

Health Emergency Management

↔ Preparedness
↔ Incident Management
↔ Emergency Operations

Health Services

↔ Hospitals
↔ Clinical Response
↔ Infection Prevention and Control

Risk Communication

↔ Public Trust
↔ Community Engagement
↔ Misinformation Management

Points of Entry

↔ Airports
↔ Ports
↔ Ground Crossings
↔ International Travel

WHO’s current monitoring framework identifies 15 capacities, including legislation, coordination, financing, laboratories, surveillance, human resources, emergency management, health services, risk communication, points of entry, zoonoses, food safety, chemical events and radiation emergencies.

Hard Capacity ↔ Soft Capacity

Hard Capacity

↔ Laboratories
↔ Hospitals
↔ Emergency Infrastructure
↔ Medical Countermeasures
↔ Surveillance Technology

Soft Capacity

↔ Coordination
↔ Leadership
↔ Risk Communication
↔ Community Engagement
↔ International Cooperation

Infrastructure without coordination → weak response

Information without trust → weak compliance

Surveillance without workforce → weak detection

Law without implementation → formal preparedness

The IHR therefore operate through both physical capacity and institutional capacity. WHO describes the framework as encompassing laboratories, emergency plans and procedures alongside multisectoral cooperation and risk communication.

Public Health Emergency of International Concern

PHEIC

↔ Exceptional International Risk
↔ WHO Director-General
↔ Emergency Committee
↔ Temporary Recommendations
↔ International Coordination

PHEIC Determination

→ epidemiological information
→ international spread
→ potential international consequences
→ Emergency Committee advice
→ WHO Director-General determination
→ temporary recommendations

PHEIC

↔ International Travel
↔ Trade
↔ Border Measures
↔ Public Communication
↔ Emergency Diplomacy

The PHEIC mechanism represents the point at which an epidemiological event becomes an international governance problem. The WHO Director-General determines whether the conditions for a PHEIC exist, with advice from an Emergency Committee.

Public Health ↔ International Commerce

Disease Control

↔ Quarantine
↔ Travel Restrictions
↔ Border Health

International Commerce

↔ Ports
↔ Airports
↔ Supply Chains
↔ Trade

IHR

↔ Health Protection
↔ Freedom of International Traffic
↔ Economic Continuity

The underlying legal balance is:

Maximum necessary health protection + Minimum unnecessary interference with international traffic and trade

This makes the IHR simultaneously a public-health instrument and an international economic-governance instrument.

WHO ↔ States Parties

States Parties

→ detect
→ assess
→ notify
→ respond
→ maintain capacities

WHO

→ receive information
→ verify information
→ conduct global surveillance
→ coordinate international response
→ provide technical assistance
→ support capacity development

Thus:

State Surveillance → WHO Early Warning → International Assessment → Coordinated Response

WHO’s authority is therefore intertwined with the quality and speed of national information systems. National IHR Focal Point

National IHR Focal Point

↔ State Government
↔ Ministries
↔ WHO
↔ Emergency Communication
↔ International Notification

Focal Point

→ national coordination
→ continuous communication
→ notification
→ verification
→ transmission of public-health information

This creates an institutional bridge:

Local Event → National Authority → National IHR Focal Point → WHO → International System

One Health

Human Health

↔ Animal Health
↔ Environmental Health

Zoonotic Disease

↔ Wildlife
↔ Livestock
↔ Agriculture
↔ Human Population
↔ Ecosystem Change

One Health

↔ IHR
↔ Zoonotic Surveillance
↔ Food Safety
↔ Antimicrobial Resistance
↔ Environmental Governance

The IHR’s capacity framework already connects human health security with zoonotic events, food safety and other biological hazards, making One Health a natural extension of international health preparedness.

Pathogen → Information → Countermeasure

Pathogen Surveillance

↔ Laboratory Science
↔ Genomic Data
↔ Epidemiological Intelligence

Pathogen Information

↔ Scientific Research
↔ Data Sharing
↔ International Cooperation

Scientific Knowledge

↔ Vaccines
↔ Diagnostics
↔ Therapeutics
↔ Medical Countermeasures

Medical Countermeasures

↔ Manufacturing
↔ Technology
↔ Supply Chains
↔ Equitable Access

The modern health-security system therefore extends beyond notification:

Pathogen → Sample → Data → Knowledge → Countermeasure → Manufacturing → Distribution

Preparedness ↔ Capacity ↔ Financing

Preparedness

↔ National Capacity
↔ Infrastructure
↔ Workforce
↔ Laboratories
↔ Emergency Planning

Capacity

↔ Financing
↔ Institutional Continuity
↔ Training
↔ Exercises

Financing

↔ Preparedness
↔ Response
↔ Resilience

A recurring structural problem is the difference between formal preparedness and operational preparedness. The IHR framework requires capacities to exist and function; monitoring systems therefore increasingly emphasise evaluation, testing and continuous improvement rather than merely the existence of plans.

Self-Assessment ↔ Independent Assessment

State Self-Assessment

↔ National Reporting
↔ SPAR
↔ Capacity Measurement

External Evaluation

↔ Joint External Evaluation
↔ Independent Verification
↔ Institutional Accountability

Preparedness Measurement

↔ Indicators
↔ Capability Levels
↔ Performance
↔ Gap Identification

The evolution is:

Declaration of Capacity → Measurement → External Evaluation → Stress Testing → Corrective Action

WHO’s current SPAR system measures 15 capacities and uses indicators and capability levels to assess implementation.

Pandemic Governance

Emerging Disease

↔ Surveillance
↔ Zoonoses
↔ Laboratory Capacity

Outbreak

↔ Notification
↔ Risk Assessment
↔ International Cooperation

Pandemic

↔ PHEIC
↔ Emergency Governance
↔ International Supply Chains
↔ Vaccines
↔ Travel
↔ Economic Disruption

Pandemic Governance

↔ IHR
↔ WHO
↔ National Governments
↔ Scientific Institutions
↔ Pharmaceutical Industry
↔ International Organizations

The IHR therefore sit inside a much larger pandemic governance architecture, rather than constituting the whole of global pandemic governance.

Human Rights ↔ Health Security

Health Measures

↔ Proportionality
↔ Necessity
↔ Non-Discrimination

Individual Rights

↔ Privacy
↔ Personal Data
↔ Informed Consent
↔ Human Dignity

International Health Security

↔ Collective Protection
↔ Individual Rights

The central tension becomes:

Collective Biological Security ↔ Individual Liberty

The IHR expressly contain safeguards concerning personal data, informed consent and non-discrimination in the application of health measures.

Information Governance

Disease Information

↔ Surveillance
↔ Verification
↔ Notification

Information

↔ Scientific Evidence
↔ Risk Assessment
↔ Public Communication

Information Failure

↔ Delayed Notification
↔ Uncertainty
↔ Misinformation
↔ Delayed Response

Information Governance

↔ Health Security
↔ International Trust
↔ State Sovereignty

The deeper principle is:

Information is the first infrastructure of epidemic control.

A laboratory may identify a pathogen, but without communication, verification and institutional transmission, knowledge cannot become international action.

Border Health

Points of Entry

↔ Airports
↔ Ports
↔ Ground Crossings

Border Health

↔ Surveillance
↔ Travel Documentation
↔ Passenger Health
↔ Conveyance Sanitation

Border Health

↔ International Trade
↔ Migration
↔ Tourism
↔ Supply Chains

Thus:

Global Mobility → Disease Mobility → Border Surveillance → International Health Regulation

Zoonoses ↔ Food Safety ↔ Antimicrobial Resistance

Zoonotic Disease

↔ Animal Health
↔ Wildlife
↔ Human Health

Food Safety

↔ Agriculture
↔ Livestock
↔ Food Supply Chains
↔ Public Health

Antimicrobial Resistance

↔ Human Medicine
↔ Veterinary Medicine
↔ Agriculture
↔ Pharmaceutical Use

One Health

↔ Zoonoses
↔ Food Safety
↔ AMR
↔ Environmental Change

This cluster expands health security from hospitals into the human–animal–environment system.

Compliance ↔ Capacity

Legal Compliance

↔ Treaty Obligations
↔ National Legislation
↔ Notification
↔ Reporting

Operational Compliance

↔ Laboratories
↔ Workforce
↔ Surveillance
↔ Emergency Response

Compliance Gap

↔ Weak Institutions
↔ Insufficient Financing
↔ Infrastructure Deficits
↔ Political Incentives

The distinction is fundamental:

Legal obligation ≠ Operational capability

A State may formally accept an international obligation while lacking the institutional capacity necessary to execute it. The history of IHR implementation demonstrates why law, finance, infrastructure and administrative capacity must be analysed together.

Global Health Security ↔ National Security

Biological Threat

↔ Public Health
↔ Economic Security
↔ Social Stability

Pandemic

↔ Supply Chains
↔ Food Security
↔ Energy Demand
↔ Labour
↔ Migration
↔ National Economy

Global Health Security

↔ Human Security
↔ Economic Security
↔ National Security
↔ International Security

The conceptual movement is:

Disease → Health Crisis → Social Disruption → Economic Disruption → Strategic Crisis
