The United States of America is the top donor and partner to WHO, contributing through assessed contributions and voluntary funding. The United States contributed US$ 1.284 billion during the 2022–2023 biennium, enabling work by WHO, the United States and other countries and partners to identify and respond to emergencies, stop disease threats from spreading across borders and advance other key global health priorities. Contributions help keep the United States and the world safe from threats while supporting better health and well-being for populations around the world, with a focus on the most vulnerable.

WHO is grateful to all the institutions of the Government of the United States of America that contribute with funding and expertise, including the U.S. Department of State, U.S. Department of Health and Human Services, the Centers for Disease Control (CDC), the Environmental Protection Agency (EPA), the United States President’s Emergency Plan for AIDS Relief (PEPFAR) and U.S. Agency for International Development (USAID).

The United States and WHO are driving global health improvements through the Global Action Plan to Accelerate Primary Healthcare, focusing on strengthening health systems and advancing universal health coverage. Efforts include boosting investments in resilient health-care systems and expanding the global health workforce to ensure preparedness and health gains worldwide.

In Africa, the United States supported WHO’s launch of the Health Workforce Investment Charter to address critical health worker needs. In the Americas, the United States and PAHO trained over 263 000 health workers through the Americas Health Corps, targeting 500 000 trained professionals by 2027. Additionally, USAID and WHO collaborated to enhance labor standards for health workers under the WHO Global Health and Care Worker Compact, ensuring better protection and equitable employment for community-health workers. These initiatives highlight the country’s commitment to empowering health workforces and strengthening global health systems.

The U.S. Department of Health and Human Services, through the FDA, supports the African Vaccine Regulatory Forum (AVAREF) to conduct clinical trials for vaccines and other medical products that are a public health priority for the continent, bolstering Africa’s capacity for vaccine and medical product regulation. This initiative ensures timely evaluation of vaccines during public health emergencies, such as the mpox outbreak.

Through collaboration with WHO’s regulatory strengthening program and the Global Benchmarking Tool, FDA assistance has helped multiple African countries enhance their regulatory systems, with six additional countries achieving Maturity Level 3 since 2022. The support from the United States towards these efforts are vital for advancing public health priorities across the continent and enhancing global health security.

The United States and WHO are partnering to strengthen digital health systems in in low- and middle-income countries, enhancing equitable access to care. In Africa, integrating immunization data into DHIS2 platforms in 12 countries has enabled real-time health tracking, helping identify underserved populations and “zero-dose” children. GIS-based mapping through the WHO Geolocated Health Facilities Data initiative has further supported countries like Nigeria, Ethiopia, and Mozambique in addressing health disparities and improving interventions, also reaching thousands of unvaccinated children in Chad and Cameroon.

The USA–WHO collaboration also plays a pivotal role in combating global HIV, advancing the 95-95-95 targets to end HIV as a public health threat by 2030. By fostering the use of longitudinal, person-centered data and implementing WHO recommendations on testing, treatment, and PrEP for prioritized populations, this partnership ensures accountability and improved service delivery. Coordination with global partners like UNAIDS and the Global Fund extends the impact of these critical efforts.

The United States is supporting WHO’s ongoing reforms to enhance efficiency, accountability, and transparency, ensuring the organization remains fit to address global health challenges. Key reforms include budget and management improvements to optimize resource use and drive impactful results.

Significant strides have also been made in preventing and responding to sexual exploitation, abuse, and harassment (PRSEAH). WHO has implemented over 90% of the 150 actions outlined in its Management Response Plan, including revising policies to close accountability gaps and establish a Prevention of and Response to Sexual Misconduct (PRSM) department. With support from the United States, WHO adopted a victim-centered approach, introduced mandatory staff training, and uses ClearCheck background screening for new hires.

Operationally, PRSEAH measures are now integrated into WHO’s health emergency responses, including mpox and Marburg plans. Dedicated teams and tools have strengthened emergency preparedness and response capacities across WHO and its partners. Sustaining these reforms is essential to maintaining WHO’s effectiveness and safeguarding vulnerable populations.
