In a world increasingly shaped by complex health threats, from pandemics and climate change to conflict and chronic disease and despite these challenges, that some of which directly affect WHO and other UN agencies, the Organization continues to lead global efforts to strengthen health security.
Guided by science and driven by solidarity, WHO works tirelessly with partners, donors, and governments to overcome obstacles and ensure the continuity of life-saving health services.
A legacy of action
From its inception, WHO has served as the global authority on health, coordinating international efforts, providing technical assistance and responding to emergencies. Its Constitution outlines a clear mandate: to direct and coordinate international health work, assist governments in strengthening health services and eradicate epidemic and endemic diseases.
This mission has translated into tangible victories. WHO led the successful eradication of smallpox, a historic achievement that was declared by WHO on 8 May 1980, following a comprehensive global vaccination and surveillance campaign. Today, it continues to push for the elimination of diseases like polio, rubella, neonatal tetanus and trachoma, which have already been eliminated in 57 countries. Forty-seven countries are now malaria-free, a testament to the power of global cooperation.
WHO’s experience in managing pandemics and epidemics is unmatched. From cholera and Ebola to SARS and COVID-19, WHO works on the frontlines, detecting thousands of health emergencies and coordinating global responses. The recent adoption of the WHO Pandemic Agreement, with its commitment to multilateral action, scientific integrity and public health protection, was a historic milestone. As WHO Director-General Dr Tedros Adhanom Ghebreyesus said: “The world is safer today thanks to the leadership, collaboration and commitment of our Member States.”
The 1978 Declaration of Alma-Ata, which emphasized primary health care as the key to achieving "Health for All", is a landmark document in public health. It calls on governments and communities to eliminate barriers to health, including malnutrition, unsafe water and poverty. WHO continues to champion this vision, integrating health into broader development agendas and advocating for universal health coverage.
The International Health Regulations (IHR), first issued in 1969 and most recently amended in 2025, embody WHO’s commitment to global health security. These legally binding regulations require countries to work together to prevent and respond to cross-border health threats, with the WHO providing evidence-based guidance.
WHO is the global standard-setter for health policies and guidelines. From tobacco control and hepatitis to hypertension and immunization, its work saves millions of lives. The Expanded Programme on Immunization, launched in 1974, prevents 3.5 to 5 million deaths annually. And in 2021, the WHO introduced a malaria vaccine that promises to save thousands more lives.
Recognizing that health is both a casualty and a pathway to peace in conflict zones, in 2019, the WHO launched the Global Health for Peace Programme. In Gaza, where hospitals are under attack and supplies are scarce, WHO staff continue to serve. Their courage in facing the most dangerous conditions amplifies the urgent need to protect health workers and ensure humanitarian access.
To meet the demands of a changing world, WHO is undergoing a major transformation. It is embracing sustainable financing and integrating artificial intelligence into global health initiatives, harnessing innovation while upholding ethical standards.
A windmill of hope
WHO is not just an institution; it is a windmill of hope, turning challenges into opportunities and guiding nations towards a healthier future.
In today’s interconnected world, the health of one nation affects every other nation. WHO must be supported – not only financially but politically and morally – to remain strong, active and committed to global health security. Its ability to coordinate responses, set standards and deliver lifesaving interventions depends on the trust and backing of its Member States and partners. Investing in the WHO means investing in a safer, healthier future for everyone.
Let us reaffirm our commitment to WHO’s mission and recognize its indispensable role in safeguarding global health.
