During 2017, nearly 250 UN Volunteers worldwide served in assignments that are clearly linked to medical professions. They bolstered the work of 23 UN partner entities, including the World Health Organization (WHO), the United Nations Populations Fund (UNFPA), UN Refugee Agency (UNHCR), United Nations Development Programme (UNDP) and UNAIDS, as well as 13 UN peacekeeping missions. Through their assignments, they contribute significantly to Sustainable Development Goal (SDG) 3, which targets achieving healthy lives and wellbeing for all.
