Health emergency and disaster risk management (H-EDRM) is the intersection of health and disaster risk reduction (DRR). In recent years, H-EDRM research has emerged as an important interdisciplinary field. This field involves various aspects including emergency and disaster medicine, DRR, humanitarian response, community health resilience, and health system resilience. The public health prevention hierarchy consists of primary, secondary and tertiary prevention. These are the most essential public health principles which guide policy and program development. The objective of primary prevention is to prevent the onset of disease with strategies including health protection and health promotion. Health protection involves the establishment of policies, regulations and programs such as vaccinations, while health promotion is mainly concerned with health education and information sharing. This book unravels the recent studies in the field of health emergency and disaster risk management. It will serve as an invaluable resource for undergraduate and post graduate students, researchers and scholars.
