Disaster epidemiology: challenges for public health action.

Better epidemiologic knowledge of the causes of death and types of injuries and illnesses caused by disasters is clearly essential to determine appropriate relief supplies, equipment and personnel needed to respond effectively to such situations. The overall objective of disaster epidemiology is to scientifically measure and describe the health effects of disasters and contributing factors to these effects, with the goals of assessing the needs of disaster-affected populations, efficient matching of resources to needs, further prevention of adverse health effects, evaluation of program effectiveness, and contingency planning. In addition, the epidemiologist has an important role to play in providing informed advice about the probable health effects which may arise in the future, in establishing priorities for action and in emphasizing the need for accurate information as the basis for relief decisions. This presentation outlines a number of important areas where epidemiologists can contribute to making disaster management more effective.
