WHO’s Role in Global Health: A Comprehensive Overview
In the mid-19th century, when pandemics like plague, cholera, and yellow fever were devastating the increasingly interconnected world, the need for an international approach to public health became evident, eventually leading to the formation of the World Health Organization (WHO).
The inception of this global health agency can be traced back to 1851, when physicians, scientists, and government leaders from around the world convened in Paris for an international health conference. This marked the beginning of what would later become WHO. Since its establishment in 1948, WHO has been working tirelessly to improve the health and well-being of people worldwide, from medical science laboratories to conflict zones, supported by scientific guidance and financial aid from 194 member countries, including the United States, which recently announced its decision to withdraw from the organization.
### WHO’s Impact on Global Health
The brief answer to the question, “What has WHO done for the world?” is, “A lot.” The organization currently provides medical services in over 150 locations worldwide, achieving significant milestones in public health.
### Emergency Response in Crisis Situations
In the face of crises, armed conflicts, disease outbreaks, and climate change, WHO has delivered vaccines and medical supplies to areas affected by wars, from Gaza to Sudan and Ukraine. In 2023, WHO reported that 1,200 attacks on medical personnel, patients, hospitals, and ambulances occurred in 19 countries and regions, resulting in 700 deaths and around 1,200 injuries.
WHO teams often reach areas where others cannot, evacuating injured patients from conflict zones and providing essential medical equipment and services. A notable example includes WHO’s efforts in Gaza, where they administered polio vaccines to children in response to an outbreak after 25 years.
### Efforts to Combat Health Crises
WHO teams analyze thousands of reports daily, monitoring diseases from Avian flu to COVID-19. The organization works relentlessly to control the spread of infectious diseases, eliminate them, and enhance access to essential medical services. This includes increasing hospital capacities and training medical workers to treat various conditions, from childbirth to treating war injuries.
### Disease Eradication
Under the right public health policies, WHO has played a significant role in the eradication of several diseases, including neglected tropical diseases, waterborne illnesses, sexually transmitted diseases, and mother-to-child transmitted disorders, all of which can be prevented with vaccines. In 2024, WHO celebrated several milestones, with seven countries (Brazil, Chad, India, Jordan, Pakistan, Timor-Leste, and Vietnam) eliminating diseases like leprosy and trachoma.
Brazil, Jamaica, and St. Vincent and the Grenadines also succeeded in preventing the mother-to-child transmission of HIV and syphilis, while Namibia reached a milestone in eliminating mother-to-child transmission of HIV and hepatitis.
### Advancements in Artificial Intelligence and Digital Health
WHO is also working in the field of artificial intelligence (AI) and digital health, striving to make this technology safe and effective for health-related applications. In 2023, the organization released guidelines on AI for diagnosing and treating diseases such as cancer and tuberculosis, outlining necessary regulatory steps to avoid unethical data collection, protect online medical privacy, and combat misinformation.
### Tackling Climate and Health Crises
Climate-related health crises now affect 3.5 billion people, or nearly half the global population. In 2023, extreme heat, weather events, and air pollution resulted in record deaths, putting immense pressure on healthcare systems and the workforce. WHO is working to protect public health from the broader effects of climate change, focusing on risks like extreme heat and epidemic outbreaks, while also helping countries adapt to climate impacts on sectors like water and food.
### WHO’s 3 Billion Targets
WHO is also working towards its “Three Billion Targets,” which aim to extend health coverage, improve emergency protection, and ensure better well-being for an additional 1 billion people by 2025. These targets align with the organization’s mission to make healthcare accessible, especially in the wake of international health crises.
### Leadership of WHO
WHO’s headquarters are in Geneva, Switzerland, and its current Director-General is Dr. Tedros Adhanom Ghebreyesus. The organization operates with a biennial budget of $6.83 billion for 2024, funded by its member countries and donors. The “World Health Assembly,” the decision-making body of WHO, consists of member nations that meet annually to establish priorities and policies. Through these efforts, WHO’s secretariat works to improve global health and well-being, continually evolving to meet emerging challenges.
WHO remains a critical player in the global health landscape, addressing the needs of vulnerable populations, responding to emergencies, and driving health innovations to improve the lives of millions worldwide.
