What is the World Health Organization: a deep dive into its role, funding, and impact
The World Health Organization (WHO) is one of the most influential international organizations in the field of public health, playing a central role in coordinating global efforts to combat diseases, improve healthcare systems, and promote well-being worldwide.
Origins of the WHO
Established in 1948 as a specialized agency of the United Nations, the WHO has been at the forefront of addressing major health crises, including pandemics, chronic diseases, and health inequalities. With 194 member states, the organization operates as a global platform where governments collaborate on health policies, share critical data, and set international health standards. The WHO’s influence extends across multiple areas, from disease eradication campaigns to health emergency responses and the establishment of medical guidelines that shape healthcare practices in both developed and developing nations.
At its core, the WHO functions as a vast network of experts, policymakers, and health professionals working together to address the most pressing health challenges of our time.
The organization is headquartered in Geneva, Switzerland, and operates through six regional offices, each responsible for addressing the specific health needs of their respective areas. These include the Regional Office for Africa, the Regional Office for the Americas, the Regional Office for the Eastern Mediterranean, the Regional Office for Europe, the Regional Office for South-East Asia, and the Regional Office for the Western Pacific. Each of these regional offices acts as a bridge between the central leadership of the WHO and the diverse healthcare systems of its member states, tailoring global strategies to the unique needs of different populations.
By collaborating with national governments, non-governmental organizations, and other UN agencies, the WHO ensures that its policies and initiatives are implemented effectively on the ground.

What does the World Health Organization do
One of the WHO’s primary functions is to provide leadership on global health matters, particularly during times of crisis. Throughout its history, the organization has been instrumental in responding to epidemics and pandemics, including smallpox, HIV/AIDS, SARS, Ebola, and, most recently, COVID-19. Its role in coordinating international efforts during the COVID-19 pandemic underscored both the strengths and challenges of global health governance.
The WHO was responsible for issuing early warnings, disseminating critical research findings, and guiding national governments on measures such as lockdowns, mask mandates, and vaccine distribution. Despite facing criticism regarding its initial response to the outbreak, the WHO remained central to international collaboration, facilitating vaccine equity through initiatives like COVAX and ensuring that lower-income countries had access to life-saving medical resources.
Beyond emergency responses, the WHO also plays a crucial role in setting health standards and providing technical assistance to member states. One of its key functions is the development of international health regulations, which serve as legally binding agreements to prevent the spread of diseases across borders.
The organization also establishes essential medical guidelines, such as those concerning maternal and child health, nutrition, and mental health. By publishing the International Classification of Diseases (ICD), the WHO provides a standardized framework for diagnosing and tracking illnesses, which is used by healthcare professionals and researchers worldwide. Additionally, it conducts extensive research on non-communicable diseases such as cancer, diabetes, and cardiovascular conditions, helping shape policies that promote healthier lifestyles and reduce the global burden of preventable diseases.

Funding of the World Health Organization: how it works
Funding is a critical aspect of the WHO’s operations, as it relies on a combination of assessed contributions from its member states and voluntary donations from governments, philanthropic organizations, and private entities. While its budget allows it to carry out extensive health programs, the organization has often faced financial constraints that limit its ability to respond rapidly to crises.

The reliance on voluntary contributions has led to concerns about potential donor influence on the WHO’s priorities, as certain governments and corporations contribute significant amounts to specific projects, which may affect the organization’s impartiality. Nonetheless, the WHO remains a vital force in global health, striving to maintain its independence while ensuring that funds are allocated to the most urgent health issues.
In addition to addressing infectious diseases and public health emergencies, the WHO has a strong focus on long-term health initiatives aimed at improving healthcare accessibility and equity. The organization works closely with countries to strengthen their health systems, ensuring that even the most vulnerable populations have access to essential medical services. This includes advocating for universal health coverage, a goal that seeks to eliminate financial barriers to healthcare and ensure that individuals receive the care they need without suffering economic hardship.
The WHO also supports vaccination programs, maternal and child health initiatives, and efforts to combat malnutrition, all of which contribute to improving life expectancy and quality of life worldwide.
The impact of the WHO is evident in many of its landmark achievements. One of the organization’s greatest successes was the eradication of smallpox in 1980, marking the first and only time in human history that a disease has been completely eliminated through coordinated global efforts. This achievement demonstrated the power of international collaboration and the effectiveness of widespread vaccination campaigns.

Similarly, the WHO has been instrumental in reducing cases of polio through aggressive immunization programs, bringing the world closer to eradicating another devastating disease. The organization has also made significant progress in the fight against malaria, tuberculosis, and HIV/AIDS, working alongside governments and NGOs to provide treatment and prevention strategies that have saved millions of lives.
Despite its accomplishments, the WHO is not without controversy. The organization has faced criticism over its handling of various health crises, with some arguing that it is too bureaucratic and slow to act in emergencies.

The response to the Ebola outbreak in West Africa (2014–2016) was widely criticized for delays in declaring an international emergency, which may have contributed to the rapid spread of the virus. Similarly, debates continue over the WHO’s role in managing the COVID-19 pandemic, with some nations questioning its relationship with China in the early days of the outbreak. However, these criticisms highlight the complexities of global health governance, where political considerations, scientific uncertainties, and logistical challenges often collide.
Looking ahead, the WHO faces numerous challenges, particularly in an era where global health threats are becoming more complex. The rise of antimicrobial resistance, climate change-related health crises, and the growing burden of mental health disorders are just a few of the pressing issues that require sustained international cooperation.
Additionally, misinformation and vaccine hesitancy have emerged as significant barriers to public health efforts, making the WHO’s role in health communication more critical than ever. The organization must continue to adapt to these evolving challenges while maintaining its credibility and authority as the world’s leading health agency.
The World Health Organization stands as a pillar of global health, dedicated to protecting and improving the well-being of people across the world. While it operates within a challenging landscape marked by political pressures, funding constraints, and unpredictable health crises, its contributions to public health are undeniable.
From eradicating diseases to guiding nations through pandemics, the WHO remains a crucial force in shaping the future of healthcare. As global health challenges become more interconnected, the organization’s ability to coordinate international responses and set health standards will continue to be essential in safeguarding the well-being of future generations.
WHO under attack: from Donald Trump to Javier Milei
Donald Trump’s criticism of the World Health Organization (WHO) arose from multiple fronts during his presidency, primarily focusing on the organization’s management of the COVID-19 outbreak.
Trump accused the WHO of being too closely aligned with China, suggesting that it failed to act swiftly or transparently regarding the virus’s origin and spread. He also claimed that the U.S. was unfairly shouldering a large portion of WHO’s budget without receiving commensurate benefits, arguing that this financial dependency compromised the organization’s independence and possibly led it to favor certain political agendas, notably those of China.
Trump’s latest decision to cut funding and eventually exit the WHO was part of his broader “America First” policy, emphasizing national sovereignty over international cooperation. This move was also politically motivated, aimed at appealing to his voter base by taking a hardline stance against international bodies. Additionally, there was a personal element to his criticism, particularly towards WHO Director-General Tedros Adhanom Ghebreyesus, whom Trump accused of favoritism.
Similarly, Javier Milei, the current President of Argentina, has mirrored Trump’s stance on the WHO, reflecting his anarcho-capitalist and nationalist views. Milei criticized the WHO for what he perceives as overreach during the global health crisis, particularly objecting to recommendations that led to lockdowns which he believed were economically detrimental and lacked sufficient scientific backing.
His decision to pull Argentina out of the WHO was explicitly linked to Trump’s actions, signaling a disdain for what he views as globalist agendas that infringe on national sovereignty. Milei’s actions align with his broader critique of international agreements and organizations, including his opposition to the Paris Climate Accord. His move against the WHO serves not only as a statement on health policy but also as part of his political strategy to appeal to voters who prioritize national autonomy and libertarian economic principles.
The criticisms from both leaders have broader implications for global health governance, potentially undermining international cooperation and weakening the WHO’s ability to respond to global health crises. Their actions have contributed to a narrative of skepticism towards international health organizations among certain political demographics, questioning the balance between national and international authority in health matters. This could lead to a push for reforms within the WHO to address criticisms concerning transparency, independence, and operational effectiveness. However, it also highlights an ongoing debate about the role of global versus national interests in managing public health emergencies.
