51 health emergencies in one year: the world normalizes its fragility
2024 and 2025 have already accumulated 51 health emergencies in 89 countries according to the World Health Organization, an unprecedented level that transforms the exception into the norm. Meanwhile, 339 million people require humanitarian assistance, representing 4% of the world’s population. This collision between the multiplication of health crises and the explosion of humanitarian needs is drawing a new geopolitical landscape where vulnerability becomes structural.
The Global Preparedness Monitoring Board (GPMB) confirms in its 2024 report what epidemiologists anticipated: epidemic cycles are accelerating and states remain in denial about investment. This normalization of emergencies reveals a troubling paradox: the more alerts multiply, the less proportionate reaction they provoke.
The essentials
- 51 health emergencies declared by the WHO in 2024-2025 in 89 countries
- 339 million people require humanitarian assistance, a record figure according to the UN
- The GPMB documents the acceleration of epidemic cycles but notes the insufficiency of preventive investments
- Global surveillance capacities remain below the needs identified after the COVID-19 pandemic
Health emergencies become the new geopolitical norm
Analysis of WHO data reveals a heavy trend: what was considered exceptional before 2020 now constitutes the standard rhythm of global health alerts. The 51 declared emergencies affect all continents with particular concentration in sub-Saharan Africa and Southeast Asia.
This multiplication is explained by the convergence of several structural factors. Climate change is expanding the areas of propagation for tropical disease vectors. Accelerated urbanization in Africa and Asia creates conditions conducive to transmission. Deforestation and agricultural expansion multiply contacts between human populations and animal pathogen reservoirs.
The WHO distinguishes three categories of emergencies within these 51 declarations: outbreaks of known diseases in new geographic areas, resurgences of epidemics thought to be under control, and the emergence of variants resistant to existing treatments. This typology reveals that the threat no longer comes solely from unknown pathogens, but from the degradation of prevention systems in the face of already-identified agents.
The paradox of information saturation amid the multiplication of crises
The 339 million people requiring humanitarian assistance represent an increase of 23% compared to 2023 according to the latest estimates from the United Nations Office for the Coordination of Humanitarian Affairs. This exponential growth in needs collides with an international response capacity that is stagnating.
The phenomenon of “compassion fatigue” documented by humanitarian organizations partly explains this inadequacy. The more emergencies multiply, the more media and political attention becomes dispersed. Institutional and private donors struggle to maintain a level of engagement proportional to the scale of needs. This saturation creates a vicious circle: underfunded crises become bogged down and generate new health vulnerabilities.
The GPMB analysis also points to a geographic bias in the international response. Health emergencies in Africa and Asia systematically receive less attention and funding than those affecting Europe or North America, creating structural imbalances in global response capacity.
Preventive investment remains trivial compared to curative costs
The GPMB’s 2024 report estimates at 31 billion dollars per year the investments necessary to establish an effective global surveillance and prevention system. This sum represents less than 3% of the 1.1 trillion dollars that the COVID-19 pandemic cost the global economy in 2020 according to estimates from the International Monetary Fund.
Yet concrete commitments remain far below identified needs. The Pandemic Preparedness Accord negotiated under the WHO’s auspices has only mobilized 7.2 billion dollars in financing pledges since its launch. This gap reveals a persistent inability of states to view health investment as a matter of national security.
Public health economists have documented this paradox for decades: every dollar invested in prevention saves between 8 and 15 dollars in curative costs depending on the pathology. But this economic logic runs into short political cycles and the difficulty of politically valuing avoided catastrophes. Leaders prefer to fund visible hospitals rather than invisible surveillance systems.
Global surveillance capacities show structural delays
The GPMB’s technical assessment reveals that only 27% of countries possess the epidemiological surveillance capacities recommended by the International Health Regulations. This proportion has remained stagnant since 2019 despite the lessons supposedly learned from the COVID-19 pandemic. Sub-Saharan Africa and Central Asia concentrate the most glaring deficits with less than 15% effective coverage.
Modern epidemiological surveillance relies on the integration of human, animal, and environmental data according to the “One Health” approach promoted by the WHO. This integration requires substantial investments in genetic sequencing technologies, communication networks, and specialized personnel training. The countries most vulnerable to epidemic emergences are precisely those lacking these technical capacities.
The COVID-19 Technology Access Pool (C-TAP) initiative launched by the WHO aimed to make surveillance and diagnostic technologies accessible. But its record remains mixed: only 23 technologies have been shared since 2020, primarily basic diagnostic tools. Patents on cutting-edge technologies remain largely concentrated in Northern countries, perpetuating capacity imbalances.
Technological innovations struggle to compensate for political failures
Paradoxically, tools for epidemiological surveillance have never been more powerful. Artificial intelligence now makes it possible to detect weak epidemic signals by analyzing data from social networks, pharmacies, and internet searches. Platforms like HealthMap at Boston Children’s Hospital or BlueDot in Canada anticipate epidemic outbreaks several weeks in advance.
These innovations, however, run into political and economic obstacles. Access to data remains fragmented by national sovereignties and commercial interests. The most sophisticated algorithms require investments that only the wealthiest states can finance, widening the preparedness gap with the most exposed areas.
The antimalarial vaccine saves one child in eight illustrates this tension: biomedical innovations progress, but their deployment remains hampered by market logic and public funding failures. Technology alone is insufficient to bridge the gap between available technical capacities and political will to invest.
Health geopolitics redraws traditional alliances
The accumulation of health emergencies is progressively transforming global geopolitical architecture. Countries that develop response capacities become unavoidable strategic actors, regardless of their traditional economic weight. Senegal and Rwanda are thus emerging as regional hubs for epidemiological surveillance in Africa through targeted investments in biotechnologies.
This redistribution creates new dependencies and opportunities for influence. China is massively funding biosecurity laboratories in Africa and Southeast Asia, positioning its pharmaceutical companies in emerging markets. The European Union is responding with the Global Health EDCTP initiative which aims to finance decentralized clinical trials in Southern countries.
The United States maintains its influence through the Centers for Disease Control and Prevention (CDC), which trains health personnel in 60 countries, but this vertical approach shows its limits when faced with more integrated strategies. The emergence of these new health balances questions the relevance of traditional multilateral organizations when dealing with issues requiring rapid and technical responses.
This geopolitical reconfiguration could accelerate if surveillance capacities become selection criteria for international investments and tourism. Some analysts anticipate the emergence of permanent “health passports” that would condition international mobility to the epidemiological capacities of destination and origin countries.
The normalization of health emergencies is silently transforming the world order. The 51 emergencies of 2024-2025 probably represent only a preview of the rhythm that will become permanently established. The question is no longer whether the world will adapt to this new situation, but which countries and organizations will develop the capacities to gain a strategic advantage from it rather than suffer it.
