What is the United States withdrawal from the WHO
The phrase US withdrawal from the WHO refers to the United States starting and then reversing its exit from the World Health Organization. This status clarifier explains the timeline, stated reasons, conditions for rejoining, and implications for global health governance and domestic public health operations.
Official process and timeline
Notice of withdrawal and effective date
Under the WHO Constitution, a member state may withdraw by notifying the Director-General. The United States submitted a formal notification in mid-2020, with the withdrawal set to take effect one year later, on July 6, 2021. This established a 12-month notice period as required by the instrument.
| Date or Period | Event | Why It Matters |
|---|---|---|
| July 6, 2020 | Formal notification of withdrawal submitted | Initiated the one-year notice clock under the WHO Constitution |
| July 6, 2021 | Withdrawal became effective | United States became a nonmember state; no participation in decision-making or World Health Assembly sessions |
| January 2025 | New administration announced intent to rejoin | Reentry process restarted by submitting a notice of intention to reverse withdrawal |
| May 2025 | Formal rejoining completed | Status restored as a full member with voting and payment obligations subject to assessed contributions and conditions |
Stated reasons for withdrawal and rejoining
Reasons cited in 2020
In 2020, authorities pointed to concerns about transparency and responsiveness during the COVID-19 response, shared decision-making and governance issues, and financial considerations, including assessed contributions and conditions attached to some voluntary funding. These issues were framed as affecting the perceived effectiveness of U.S. engagement within the organization.
Conditions for rejoining stated in 2025
When rejoining was announced, the stated prerequisites emphasized clearer alignment on shared governance, greater transparency in operations and emergency declarations, adherence to processes that respect member-state views, and predictable, rules-based funding arrangements that avoid mandatory earmarks.
Implications for global health and U.S. interests
Risks and trade-offs of nonmembership
- Reduced influence on global health norms, standards, and emergency responses
- Limited access to real-time data, technical guidance, and coordinated outbreak response
- Potential delays in vaccine and therapeutic allocation decisions affecting U.S. interests during cross-border health threats
- Continued obligations for assessed contributions upon rejoining, including any arrears accumulated during nonmembership
Benefits of membership
Membership provides access to WHO-led initiatives in surveillance, disease control, and health system support; a seat in decisions that shape international health regulations; and mechanisms for coordinating multinational responses to pandemics and cross-border health risks.
Key definitions
