This interim guidance note has been developed in response to the outbreak of COVID-19 and its likely impact on humanitarian operations around the world, building on work done by the Grand Bargain Localisation Workstream. It provides guidance as to how the international humanitarian community can adapt its delivery modalities in response to COVID-19 consistent with existing commitments on localisation of aid, strengthening partnerships with local and national actors, and operating effectively in an environment affected by COVID-19. It is relevant to all countries covered by the COVID-19 Global Humanitarian Response Plan (GHRP).
