Implementing IHR (2005): Strategies for Global Health Security

When disease outbreaks occur, they don’t respect borders. The 2014 Ebola epidemic in West Africa resulted in over 11,000 deaths and cost approximately $2.2 billion in economic losses, demonstrating how quickly a local outbreak can become a global health crisis. This is precisely why the International Health Regulations (IHR) 2005 exist-to ensure countries worldwide can detect, assess, and respond to health threats before they spread. But having regulations on paper is one thing; implementing them effectively is quite another.

Understanding the IHR implementation framework 🔗

The IHR is a legally binding agreement between 196 countries that defines how nations should collectively manage disease outbreaks and other public health emergencies. The regulations came into force in June 2007, requiring all member states to develop core public health capacities within five years. However, by 2012, only 42 of 194 states parties declared they had met their core capacity requirements, and by 2014, fewer than one-third of countries were fully prepared to detect and respond to outbreaks.

The gap between commitment and implementation became painfully clear during the Ebola outbreak. This reality sparked renewed international efforts to strengthen global health security through more rigorous implementation strategies.

Seven strategic actions for effective implementation 🔗

To help countries navigate the complexities of IHR implementation, the World Health Organization developed seven strategic areas of work that form the foundation of national preparedness efforts:

Foster global partnerships 🔗

In an interconnected world, no country can tackle health threats alone. Global partnerships enable countries to share technical expertise, provide mutual support during crises, and promote transparency. These partnerships extend beyond health ministries to include sectors like agriculture, trade, education, and defense-all essential for building comprehensive alert and response systems.

Strengthen national disease prevention, surveillance, control and response systems 🔗

Countries must develop robust surveillance systems that can detect acute public health events in a timely manner. This includes establishing laboratory networks, training epidemiologists, and implementing real-time disease monitoring systems that function from community level to national coordination centers.

Strengthen public health security in travel and transport 🔗

Airports, seaports, and ground crossings serve as critical entry points for potential health threats. The IHR requires countries to maintain core capacities at designated points of entry, including the ability to screen travelers, manage sick individuals, and implement necessary health measures without causing unwarranted disruption to international traffic.

Strengthen WHO global alert and response systems 🔗

Each country must designate a National IHR Focal Point that remains accessible 24/7 for communications with WHO. In the United States, for example, the HHS Secretary’s Operations Center monitors IHR communications continuously and coordinates event assessments across government agencies.

Strengthen the management of specific risks 🔗

Different types of health threats require specialized approaches. Countries must develop targeted strategies for managing chemical hazards, radiation emergencies, zoonotic diseases, antimicrobial resistance, and other specific risks that could trigger public health emergencies.

Sustain rights, obligations and procedures 🔗

Implementation requires embedding IHR requirements into national legislation and administrative procedures. This includes protecting travelers’ rights, ensuring informed consent, preventing discrimination, and maintaining data privacy while managing public health responses.

Conduct studies and monitor progress 🔗

Countries must regularly assess their IHR capacities through annual self-assessment reports using the State Party Self-Assessment Annual Reporting (SPAR) tool. These assessments track progress across 15 capacities and 35 indicators, providing a clear picture of preparedness strengths and gaps.

Navigating implementation challenges 🔗

Despite clear frameworks, countries face significant obstacles in achieving full IHR compliance. Understanding these challenges is crucial for developing effective solutions.

Resource constraints and funding gaps 🔗

Many countries struggle to allocate sufficient domestic resources for building core capacities. While states parties committed to providing funding for IHR implementation, national budgets often prioritize immediate health needs over preparedness for uncertain future threats. Finding resources to support health system capacity building remains one of the most persistent challenges, particularly in countries with limited economic means.

Weak accountability mechanisms 🔗

The IHR relies primarily on self-assessment and voluntary external evaluation rather than enforcement mechanisms. This approach respects national sovereignty but can lead to inconsistent reporting. A recent study identified 135 implementation challenges, including inadequate governance, insufficient cooperation between countries, and lack of enforcement accountability.

Multisectoral coordination difficulties 🔗

Effective IHR implementation requires coordination across multiple government sectors-health, agriculture, defense, finance, customs, and more. However, inadequate compliance of states with IHR obligations, particularly on preparedness, contributed to COVID-19 becoming a protracted global health emergency. Breaking down silos between sectors and establishing functional coordination mechanisms remains a significant hurdle.

Technical capacity gaps 🔗

Many countries lack sufficient laboratory capacity, trained epidemiologists, and modern surveillance infrastructure. The 2024 SPAR data revealed that multisectoral engagement-a critical component of preparedness-actually declined from 76% in 2023 to 73% in 2024, highlighting ongoing struggles with coordination and capacity.

Learning from success: Taiwan’s JEE implementation 🔗

While challenges are numerous, some countries have demonstrated remarkable success in implementing IHR core capacities. Taiwan’s experience with the Joint External Evaluation (JEE) process offers valuable lessons for other nations.

Strategic preparation and stakeholder engagement 🔗

Taiwan’s success began with extensive preparatory work. Following the devastating SARS outbreak in 2003, the country committed to strengthening its health security. When WHO developed the JEE tool in February 2016, Taiwan voluntarily engaged at least 19 government agencies to conduct a comprehensive external evaluation.

The key to Taiwan’s success was a 10-month preparation period that included advocacy of the One Health concept among stakeholders, securing high-level political commitment, and building a culture of transparency and accountability. This groundwork ensured that when external evaluators arrived, all sectors were prepared to participate meaningfully.

The pilot visit approach 🔗

Taiwan’s implementation strategy included an innovative pilot visit by external experts before the full evaluation. During this visit, experts met with individual team members responsible for specific JEE elements, clarified questions, and discussed how responses should be drafted. This approach reduced anxiety, avoided misunderstandings, and helped team members take ownership of the process.

Multisectoral collaboration in action 🔗

The evaluation process involved representatives from health, agriculture, defense, border control, environmental protection, and nuclear power sectors. Each agency contributed expertise to address elements beyond traditional health ministry responsibilities. This whole-of-government approach ensured comprehensive assessment of all IHR core capacities.

Transparency and continuous improvement 🔗

Taiwan published its JEE results in October 2016, becoming only the eighth country to do so. Rather than viewing the evaluation as a one-time exercise, Taiwan developed a four-year implementation plan with an annual budget of $7.5 million to address identified gaps. The government also proposed establishing post-JEE monitoring mechanisms at the highest political level to ensure sustained progress.

Regional success stories: Africa’s JEE experience 🔗

The African region provides another compelling case study in IHR implementation. Between 2015 and the present, all 47 countries in the WHO African Region plus the island of Zanzibar completed Joint External Evaluations. This achievement required deploying 360 subject matter experts from 88 different organizations across 607 deployment instances.

Key lessons from the African experience include the importance of country leadership and ownership, conducting orientation workshops before self-assessment, involving One Health stakeholders throughout the process, and ensuring dedicated staff for coordination and report writing. The region’s success demonstrates that with proper support and commitment, even resource-constrained settings can make significant progress in implementing IHR core capacities.

Building toward global health security 🔗

The COVID-19 pandemic revealed both the strengths and weaknesses of global IHR implementation. While some countries demonstrated robust preparedness and rapid response capabilities, others struggled with basic detection and reporting functions. The pandemic underscored that global health security depends on the preparedness of every nation-a chain is only as strong as its weakest link.

Moving forward, successful IHR implementation requires sustained political commitment at the highest levels, adequate and predictable financing, functional multisectoral coordination mechanisms, and regular monitoring through tools like SPAR and JEE. Countries must view IHR implementation not as a compliance exercise but as a fundamental investment in protecting their populations and contributing to global health security.

The path from regulations to action is neither quick nor easy, but the stakes could not be higher. As infectious disease threats continue to emerge and spread with increasing speed, the world needs every country to fulfill its IHR commitments. By learning from successful implementations, addressing known challenges, and maintaining sustained commitment, nations can build the resilient health systems necessary to prevent the next pandemic.

What do you think? How can countries with limited resources effectively balance competing health priorities while building IHR core capacities? What role should international partners play in supporting nations that struggle to meet implementation deadlines?
