"This document presents the key issues to be considered in the process of setting up and implementing public health alert, response and operational plans for MGs. It sets out methods for assessing the needs of the MG, determining the ability of existing systems to meet those needs, and modifying and strengthening those systems where required. It provides advice about prevention, detection and management of public health incidents, as well as the integration of the full range of public health activities into the MG planning process. It addresses the many different types of MG, provides case studies of the work undertaken for public health activities at various MGs, and supporting papers and additional resources to support the information here. This document has been developed primarily for public health professionals, as well as key policy makers, planners and executive personnel. In addition to those in the health sector, there are many outside authorities involved in contributing to healthy outcomes at MGs, who will also find this document useful. It is further anticipated that it will be a valuable resource for event promoters and managers, emergency service personnel, government bodies, and any organizations or individuals who contribute to the organization of MGs. Wide distribution should be encouraged, providing it is understood that while many factors influence the wellbeing of those attending MGs, the detailed contents of this document are directed principally at managing public health issues that influence health and safety at a MG."--Page 12.
