Although this document is intended primarily as a backdrop for interventions involving refugees, it is also suitable as a guide for ensuring adequate vitamin C intake in most emergency settings. It reviews the strategies and past experiences of the prevention of scurvy in refugee situations, and analyses factors influencing their success or failure. It reviews the constraints to the adoption of the recommendations. Innovative ways of improving vitamin C intakes are recommended and interventions are proposed for field-testing. Also included are a literature review of the epidemiology of scurvy and its signs and symptoms, the properties and functions of vitamin C, and a discussion of food sources of this vitamin and its stability. The recommended daily allowance (RDA) for vitamin C, including "minimum" as distinct from "optimum" intakes, is also discussed.
