This document was developed under the auspices of USAID’sNutrition Leadership Council (NLC). It summarizes the likely impacts of the COVID-19 crisis on nutrition and proposes guiding principles for priority actions during the response and recovery phases. The crisis is creating shocks across multiple sectors and systems that are essential to improving and safeguarding nutrition. In a vicious cycle, shocks to nutritional status will increase morbidity and mortality and are likely to increase populations’ vulnerability to adverse outcomes.
