Why Another Pandemic Remains a Real Global Threat

The COVID-19 crisis revealed how vulnerable the world is to fast-spreading infectious diseases, yet many of the systemic weaknesses it exposed remain largely unresolved.¹ While attention has shifted to other priorities, the probability and potential impact of another devastating pandemic are still uncomfortably high.² This article explores why concern remains justified, what is changing at the global level, and how a more realistic approach to pandemic preparedness could save tens of millions of lives.

Why Future Pandemics Are Not a Remote Risk

Far from being a once-in-a-century fluke, large outbreaks are becoming more likely due to converging biological, environmental, and political trends.

Drivers that increase pandemic risk

• Rising spillover from animals to humans – Population growth, deforestation, and intensive farming increase contact between humans and wildlife, raising the chance that novel pathogens jump species.
• Climate change – Warming temperatures expand the habitats of disease-carrying mosquitoes and other vectors, altering patterns of transmission and enabling pathogens to reach new regions.¹
• Urbanization and global travel – Dense cities and rapid air travel allow local outbreaks to become global threats in days.
• Political fragility and conflict – Weakened health systems, displacement, and mistrust can turn containable outbreaks into humanitarian disasters.
• Advancing biotechnology – Powerful tools like synthetic biology and gene editing enable faster vaccine development but also lower barriers to engineering dangerous pathogens.⁴

According to a high-level panel convened for the G20, the frequency and diversity of infectious disease outbreaks continue to increase, while financing and political attention for pandemic preparedness are eroding.⁴ This widening gap between risk and readiness is the core reason serious people remain worried about the next pandemic.

Natural, accidental, and deliberate threats

Future pandemics could emerge through three broad pathways:

• Natural emergence – A novel virus arises in animals and spills over into human populations.
• Laboratory accidents – Mistakes or poor safety practices release a dangerous pathogen into the community.
• Deliberate misuse – State or non-state actors intentionally create or release harmful biological agents.⁴

Scientific advances bring immense benefits, but dual-use capabilities make it easier both to detect threats and to create them. Balancing innovation with safety and governance is now a central challenge for global biosecurity.

What We Learned from COVID-19 — and Still Haven’t Fixed

COVID-19 catalyzed unprecedented scientific collaboration and vaccine development, yet it also highlighted fundamental failures in preparedness and response.

Successes that show what is possible

• Rapid vaccine development – Safe and effective vaccines were created and authorized in under a year, far faster than previous records, thanks to decades of mRNA research and coordinated trials.¹
• Data sharing and genomic surveillance – Sequencing centers around the world shared viral genomes, enabling quicker detection of variants and informing public health measures.¹
• Emergency response capacity – Many countries built temporary infrastructure for testing, tracing, and hospital surge capacity, demonstrating what can be done under pressure.

These successes prove that with enough attention, funding, and coordination, humanity can respond quickly to novel threats. The question is whether that urgency will be sustained between crises.

Failures that left millions vulnerable

Despite scientific breakthroughs, the world suffered massive loss of life, economic damage, and long-term health consequences. Key failures included:

• Slow and fragmented early responses – Many governments delayed action, allowing exponential spread before basic measures like testing and masking were widely implemented.
• Weak public health infrastructure – Under-resourced health systems struggled to scale up testing, contact tracing, and intensive care capacity.
• Inequitable access to vaccines and treatments – High-income countries secured most early vaccine supplies, while low-income countries waited much longer, deepening existing inequalities.²
• Misinformation and mistrust – Conflicting messages and politicization undermined adherence to public health advice.
• Economic and social disruption – Lockdowns and border closures had profound effects on livelihoods, education, and mental health.

A 2025 global report warns that inequality is now a key driver of vulnerability: surviving the next pandemic could depend heavily on where you live and what resources your country can mobilize.⁹

New Global Efforts: The WHO Pandemic Agreement and Beyond

Recognizing that the status quo was not acceptable, governments and international organizations have launched new frameworks to strengthen collective preparedness.

The WHO Pandemic Agreement

In May 2025, Member States at the World Health Assembly adopted a new Pandemic Prevention, Preparedness and Response Agreement (often called the WHO Pandemic Agreement).³ This legal instrument aims to address critical gaps exposed by COVID-19 and to coordinate global action before and during future crises.

The Agreement works in tandem with the revised International Health Regulations, updated in 2024, which outline how countries should detect and report public health emergencies of international concern.¹ Together, they form a legal backbone for more coordinated global responses.

Financing the global pandemic safety net

Institutions and expert panels have stressed that without reliable funding, even strong legal frameworks will fail. A G20 High Level Independent Panel concluded that global pandemic preparedness stands “at a precipice” as aid and domestic allocations decline.⁴ Their recommendations emphasize:

• Integrating pandemic preparedness into national budgets rather than treating it as an emergency add-on.⁴
• Expanding the role of multilateral development banks and dedicated facilities like The Pandemic Fund to support country-level capacity building.⁸
• Financing security measures to reduce the risk of deliberate or accidental biological events, not just natural outbreaks.⁴

The Pandemic Fund, hosted by the World Bank, helps low- and middle-income countries strengthen core capabilities such as surveillance, laboratories, and emergency operations centers.⁸ However, current resources remain far below what independent experts estimate is needed to manage global biological risks effectively.

Strategic planning for specific threats

The World Health Organization has also released a 2025–2030 strategic plan to help countries manage coronavirus threats, including COVID-19 and MERS, within broader infectious disease control.⁵ The plan focuses on:

• Integrating COVID-19 management into routine health services rather than treating it solely as an emergency.
• Strengthening laboratory and genomic surveillance capacities.
• Ensuring sustainable access to vaccines and treatments for high-risk groups.⁵
• Promoting equity and resilience so that systems can flex between routine care and crisis response.

These efforts underscore a growing recognition: the line between “ordinary” disease control and “emergency” pandemic response is increasingly blurred. Health systems must be able to shift gears quickly.

Core Pillars of Serious Pandemic Preparedness

Turning concern into meaningful action requires investing in a set of mutually reinforcing pillars that can reduce both the probability and the impact of future pandemics.

1. Early detection and transparent reporting

Speed is the single most valuable asset in stopping outbreaks. Effective systems share several features:

• Robust surveillance networks – Continuous monitoring of hospitals, clinics, and laboratories to detect unusual clusters of illness.
• Genomic sequencing – Routine sequencing of pathogens to spot new variants or novel viruses.
• Rapid, honest reporting – Countries need both technical capacity and political incentives to report threats quickly, even when there may be economic or reputational costs.
• Integrated data platforms – Real-time data sharing within and across borders, supported by clear standards and privacy protections.

2. Strong, flexible health systems

Pandemics hit hardest where health systems are already fragile. Resilient systems share several traits:

• Trained and adequately paid health workers across primary care, public health, and specialized services.
• Reliable supply chains for essential medicines, oxygen, and personal protective equipment.
• Emergency operations centers and clear incident management systems.
• Capacity to rapidly scale up hospital and intensive care services when needed.

Strengthening these foundations improves everyday health outcomes while also serving as insurance against catastrophic outbreaks.

3. Research, development, and innovation

Scientific advances during COVID-19 showed the lifesaving potential of sustained research and development (R&D). The 2025 WHO Pandemic Agreement explicitly highlights the need for continuous investment in R&D infrastructure, skills, and clinical trials as a core component of preparedness.¹ Priorities include:

• “Prototype” vaccines and antiviral platforms for families of viruses with pandemic potential.
• Broad-spectrum therapeutics and monoclonal antibodies.
• Rapid, affordable diagnostic tests that can be deployed at scale.
• Safe, secure use of AI and computational tools to accelerate discovery while managing dual-use risks.⁴

4. Risk communication and community trust

No public health measure works without public cooperation. Managing future pandemics will require:

• Clear, consistent messaging from trusted institutions.
• Pre-established channels to reach vulnerable and marginalized groups.
• Engagement with community leaders, civil society, and local health workers.
• Proactive strategies to counter misinformation and build media literacy.

Trust must be built before crises, not invented in the middle of them.

5. Fair distribution of tools and benefits

Unequal access to vaccines, diagnostics, and therapeutics during COVID-19 was not only unjust; it also allowed the virus to circulate and mutate, prolonging the pandemic.² A more equitable system requires:

• Advance agreements on sharing pathogen samples and the benefits derived from them, such as vaccines and treatments.
• Financing mechanisms that support manufacturing and delivery in low- and middle-income countries.
• Intellectual property and licensing models that enable rapid scaling while preserving incentives for innovation.

The Pandemic Agreement’s focus on equitable access and coordinated financing is a step toward correcting these structural imbalances.³

What Governments, Institutions, and Individuals Can Do

Pandemic preparedness is often framed as the responsibility of health ministries and international organizations, but meaningful progress requires coordinated action from many actors.

Actions for governments and policymakers

• Formally endorse and implement international instruments like the WHO Pandemic Agreement and the revised International Health Regulations.¹
• Integrate pandemic preparedness into national security and development strategies, with multi-year funding commitments.⁴
• Invest in laboratories, surveillance systems, and training programs, especially at the local and regional levels.
• Support responsible biotechnology by setting and enforcing biosecurity and biosafety standards for research and industry.
• Collaborate across borders and political divides, recognizing that pathogens ignore sovereignty.

Roles for multilateral organizations and donors

• Scale up financing through mechanisms like The Pandemic Fund and other global health initiatives.⁸
• Support regional manufacturing hubs for vaccines and diagnostics.
• Provide technical assistance and capacity building for countries with limited resources.
• Monitor and transparently report on global preparedness gaps, as boards and independent panels have begun to do.²

How individuals and professionals can contribute

• Public understanding – Stay informed about infectious disease risks and support evidence-based public health measures.
• Professional choices – People in medicine, biology, data science, policy, and communication can choose careers or projects that directly strengthen preparedness and biosecurity.
• Civic engagement – Citizens can advocate for sustained investment in health systems and global cooperation, rather than short-term crisis responses.

Frequently Asked Questions (FAQs)

Q: If we handled COVID-19, why is there still so much concern about the next pandemic?

COVID-19 was devastating despite unprecedented scientific advances; millions died, health systems were overwhelmed, and economies suffered large losses. Expert panels and global health authorities report that core vulnerabilities and financing gaps remain unresolved, while the drivers of new outbreaks are intensifying.¹²⁴

Q: What is the main purpose of the WHO Pandemic Agreement?

The Agreement is designed to strengthen global prevention, preparedness, and response by addressing gaps revealed during COVID-19, including weak coordination, unreliable funding, and highly unequal access to vaccines, diagnostics, and treatments.¹³

Q: How does climate change affect the risk of pandemics?

Climate change alters temperature and rainfall patterns, expanding the range of disease-carrying vectors like mosquitoes and changing the distribution and seasonality of infectious diseases. It also contributes to ecosystem disruption that can increase the likelihood of new pathogens emerging.¹

Q: Are advances in biotechnology making pandemics more or less likely?

Biotechnology enables faster development of vaccines, diagnostics, and treatments, which can greatly reduce the impact of outbreaks. At the same time, tools like synthetic biology and gene editing lower technical barriers to engineering pathogens, increasing concern about accidental or deliberate biological events. Effective regulation and biosecurity practices are essential to capture benefits while limiting risks.⁴

Q: What can low- and middle-income countries do if they lack resources?

Countries with fewer resources can prioritize building core public health capacities, engage in regional cooperation, and seek support from mechanisms such as The Pandemic Fund and WHO technical programs. International agreements increasingly recognize the need for financial and technical assistance to ensure that all countries can meet minimum preparedness standards.³⁸
