This Guidance Note is provided for general relief workers and volunteers, health care and protection workers, programme managers, and any other personnel helping those affected by the Haiti earthquake. It provides guidance to organisations working in Haiti about how they can most appropriately communicate with communities, their own personnel and the media. The Guidance Note focuses mainly on the acute phase of the response (including early recovery) and provides basic guidance for action. Please use the IASC Guidelines for more detailed information on the appropriate response in all sectors.
