Which organization leads international public health and global health efforts under the United Nations?

• A. World Health Assembly
• B. UNICEF
• C. World Health Organization (WHO)
• D. International Red Cross

Answer: (C)

The question targets understanding which body leads international public health within the United Nations system. The World Health Organization is the specialized UN agency charged with directing and coordinating global health efforts. It sets international health standards, supports disease surveillance and control, and provides technical assistance and emergency response coordination to countries around the world. The decision-making body within WHO is the World Health Assembly, but that body operates under the organization, not as the leading agency itself. UNICEF focuses on child health and welfare, not the broad umbrella of global health leadership, and the International Red Cross is a separate humanitarian network, not a UN health agency. So, the World Health Organization is the correct lead for international public health within the UN.
