Following Trump's withdrawal of the US from the WHO, concerns about funding arose, as the US was the largest contributor in 2024. The WHO relies on member state fees and voluntary contributions, with significant portions allocated to health services and disease prevention. Dr. Tedros Adhanom Ghebreyesus stated the organization can adapt to the funding loss. WHO employee Tania Cernuschi launched the '1 Dollar, 1 World' campaign to raise funds, aiming for $1 billion, but has only raised about $70,076.95 so far.
