Refugees face significant threats to their physical safety, health, and livelihoods. Standardized care for refugees comprises a range of services and treatments to address their basic need for survival, such as the provision of food, water, basic medical care, and the control of epidemics. These services are commonly provided by international humanitarian organizations in collaboration with United Nations (UN) agencies. Over the last several decades, the level of care for refugees has expanded beyond the provision of emergency services to encompass a broad range of more complex and specialized services, including those to address sexual, reproductive, and mental health. Provisions outlining care for refugees are established in international law, and involve legal obligations for UN member states to ensure minimal assistance for survival.
