The United Nations International Children's Emergency Fund (UNICEF) was formed in 1946 to provide humanitarian assistance to children in developing countries. It aims to develop community services to promote children's health and well-being in areas such as nutrition, immunization, water and sanitation, education, and child protection. UNICEF operates in 191 countries through country programs and national committees, guided by a 36-member executive board. It focuses on issues like nutrition, immunization, HIV prevention, water and sanitation, education, and protecting children from violence.
